691638 divided by 57 
We want to divide 691638 by 57.

Step 1:
The number 57 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 57

Advancing to step 2:
If we divide 69 by 57, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 57 from 69 leaves us with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 57

On to step 3:
When dividing 121 by 57, we get 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 114 away from 121, we end up with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 57

Going ahead to step 4:
When dividing 76 by 57, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 121.0
If we subtract 57 from 76, we get 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 57

Step 5:
57 can be fit into 193 3 times, resulting in a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 1213.0
Subtracting 171 from 193 leaves us with 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 57

Step 6:
When dividing 228 by 57, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 12134.0
If we take 228 away from 228, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
If we divide 0 by 57, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12134.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 57 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12134.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 12134.0, and the remainder is 0.0.
