631871 ÷ 53 
Our goal is to divide 631871 by 53.

On to step 1:
6 divided by 53 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 53

On to step 2:
63 divided by 53 is 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 53 from 63 to get 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 53

Step 3:
When dividing 101 by 53, we get 1 with a remainder of 48.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 53 from 101, we get 48.
Bring next digit (8) of the dividend behind the 48 and repeat the process: 488 / 53

Going ahead to step 4:
488 divided by 53 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 119.0
If we take 477 away from 488, we end up with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 53

Advancing to step 5:
When dividing 117 by 53, we get 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 1192.0
If we subtract 106 from 117, we get 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 53

Going ahead to step 6:
111 divided by 53 is 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 11922.0
Deduct 106 from 111 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
53 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 11922.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
53 goes into 500 9 times with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 11922.09
Subtracting 477 from 500 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
The number 53 fits into 230 4 times, leaving a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 11922.094
Subtract 212 from 230 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
When dividing 180 by 53, we get 3 with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 11922.0943
Subtracting 159 from 180 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 11:
210 divided by 53 is 3 with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 11922.09433
The remainder is 51 after subtracting 159 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 11922.09433, with a leftover of 5.1e-05.
