We look at the division of 891570 by 9 
We want to divide 891570 by 9.

Let's proceed to step 1:
8 divided by 9 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 9

Let's proceed to step 2:
If we divide 89 by 9, we get 9 and a remainder of 8.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 81 from 89 leaves us with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 9

Going ahead to step 3:
The number 9 fits into 81 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 99.0
Deduct 81 from 81 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 9

Going ahead to step 4:
When dividing 5 by 9, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 990.0
If we subtract 0 from 5, we get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 9

On to step 5:
If we divide 57 by 9, we get 6 and a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 9906.0
Deduct 54 from 57 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 9

On to step 6:
30 divided by 9 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 99063.0
The remainder is 3 after subtracting 27 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 9, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 99063.3
If we take 27 away from 30, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
30 divided by 9 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 99063.33
The remainder is 3 after subtracting 27 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The quotient of the division is 99063.33, and the remainder is 0.003.
