Step-by-step explanation

1. Parse fraction to decimal repeating input

$\frac{81}{47}$

Operation detected: fraction to decimal repeating conversion.

$\frac{81}{47}$

Normalize numerator and denominator from the input.

$\frac{81}{47}$

Rewrite the fraction as a long-division setup.

$81 \div 47$

Plan: generate digits while tracking remainders to detect repetition.

$81 \div 47$

Parse the fraction and set up long division before generating decimal digits.

2. Execute long-division cycle transcript

$\frac{81}{47}$

At each cycle: multiply remainder by 10, divide by denominator, record digit and new remainder.

$\frac{81}{47}$

$\frac{340}{47} = d i g i t 7, r e m a \in d e r 11$

This cycle contributes one new decimal digit.

$11$

$\frac{110}{47} = d i g i t 2, r e m a \in d e r 16$

This cycle contributes one new decimal digit.

$16$

$\frac{160}{47} = d i g i t 3, r e m a \in d e r 19$

This cycle contributes one new decimal digit.

$19$

$\frac{190}{47} = d i g i t 4, r e m a \in d e r 2$

This cycle contributes one new decimal digit.

$2$

$\frac{20}{47} = d i g i t 0, r e m a \in d e r 20$

This cycle contributes one new decimal digit.

$20$

$\frac{200}{47} = d i g i t 4, r e m a \in d e r 12$

This cycle contributes one new decimal digit.

$12$

$\frac{120}{47} = d i g i t 2, r e m a \in d e r 26$

This cycle contributes one new decimal digit.

$26$

$\frac{260}{47} = d i g i t 5, r e m a \in d e r 25$

This cycle contributes one new decimal digit.

$25$

$\frac{250}{47} = d i g i t 5, r e m a \in d e r 15$

This cycle contributes one new decimal digit.

$15$

$\frac{150}{47} = d i g i t 3, r e m a \in d e r 9$

This cycle contributes one new decimal digit.

$9$

$\frac{90}{47} = d i g i t 1, r e m a \in d e r 43$

This cycle contributes one new decimal digit.

$43$

$\frac{430}{47} = d i g i t 9, r e m a \in d e r 7$

This cycle contributes one new decimal digit.

$7$

$\frac{70}{47} = d i g i t 1, r e m a \in d e r 23$

This cycle contributes one new decimal digit.

$23$

$\frac{230}{47} = d i g i t 4, r e m a \in d e r 42$

This cycle contributes one new decimal digit.

$42$

Cycle transcript shortened for readability; continue using the same pattern.

$14$

A remainder repeated, so digits from that point form the repeating cycle.

$1. (7234042553191489361702127659574468085106382978)$

A repeated remainder appears, so the repeating block is $7234042553191489361702127659574468085106382978$ .

3. Conclude decimal representation

$81 / 47 = 1. (7234042553191489361702127659574468085106382978)$

$1. (7234042553191489361702127659574468085106382978)$

Conclusion: the fraction converts to a repeating decimal.

$1. (7234042553191489361702127659574468085106382978)$

Study tip: keep parentheses around repeating digits to preserve exact value.

$1. (7234042553191489361702127659574468085106382978)$

Write the repeating decimal with parentheses: $1. (7234042553191489361702127659574468085106382978)$ .
