Penjelasan langkah demi langkah
1. Escreva o divisor, que é 9, e depois escreva o dividendo, que é 81, para preencher a tabela.
| TABLE_COL_WHOLE_DIGIT2_PLACE1 | TERM_TABLE_COL_DIVISION_ACTION | zehner | einser |
| / | |||
| 9 | 8 | 1 |
2. Divida os dígitos do dividendo pelo divisor um de cada vez, começando da esquerda.
Para dividir 8 por divisor 9, nos perguntamos: 'Quantas vezes podemos encaixar 9 em 8?
8/9=0
Escreva o quociente 0, acima do dígito que dividimos.
| TABLE_COL_WHOLE_DIGIT2_PLACE1 | TERM_TABLE_COL_DIVISION_ACTION | zehner | einser |
| / | 0 | ||
| 9 | 8 | 1 | |
Multiplicamos o quociente pelo divisor para obter o produto.
9*0=0
Escreva 0 abaixo dos dígitos que acabamos de dividir (8), para que possamos subtrair e obter o resto.
| TABLE_COL_WHOLE_DIGIT2_PLACE1 | TERM_TABLE_COL_DIVISION_ACTION | zehner | einser |
| × | 0 | ||
| 9 | 8 | 1 | |
| 0 |
Subtraia para obter o resto
8-0=8
Escreva o resto 8
| TABLE_COL_WHOLE_DIGIT2_PLACE1 | TERM_TABLE_COL_DIVISION_ACTION | zehner | einser |
| 0 | |||
| 9 | 8 | 1 | |
| - | 0 | ||
| 8 |
Como temos um resto da divisão anterior, trazemos o próximo dígito, que é (1), e adicionamos ao resto (8).
| TABLE_COL_WHOLE_DIGIT2_PLACE1 | TERM_TABLE_COL_DIVISION_ACTION | zehner | einser |
| 0 | |||
| 9 | 8 | 1 | |
| - | 0 | ||
| 8 | 1 |
Para dividir 81 por divisor 9, nos perguntamos: 'Quantas vezes podemos encaixar 9 em 81?
81/9=9
Escreva o quociente 9, acima do dígito que dividimos.
| TABLE_COL_WHOLE_DIGIT2_PLACE1 | TERM_TABLE_COL_DIVISION_ACTION | zehner | einser |
| 0 | 9 | ||
| 9 | 8 | 1 | |
| - | 0 | ||
| 8 | 1 | ||
Multiplicamos o quociente pelo divisor para obter o produto.
9*9=81
Escreva 81 abaixo dos dígitos que acabamos de dividir (81), para que possamos subtrair e obter o resto.
| TABLE_COL_WHOLE_DIGIT2_PLACE1 | TERM_TABLE_COL_DIVISION_ACTION | zehner | einser |
| × | 0 | 9 | |
| 9 | 8 | 1 | |
| - | 0 | ||
| 8 | 1 | ||
| 8 | 1 |
Subtraia para obter o resto
81-81=0
Escreva o resto 0
| TABLE_COL_WHOLE_DIGIT2_PLACE1 | TERM_TABLE_COL_DIVISION_ACTION | zehner | einser |
| 0 | 9 | ||
| 9 | 8 | 1 | |
| - | 0 | ||
| 8 | 1 | ||
| - | 8 | 1 | |
| 0 |
O resultado final é: 9
