We divide 86072012 by 631
Our goal is to divide 86072012 by 631.

Advancing to step 1:
When dividing 8 by 631, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 631

On to step 2:
The number 631 fits into 86 0 times, leaving a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (0) from the dividend, attach it to 86 and continue: 860 / 631

Advancing to step 3:
631 can be fit into 860 1 times, resulting in a remainder of 229.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 631 from 860 and we're left with 229.
Fetch the next digit (7) from the dividend, attach it to 229 and continue: 2297 / 631

Advancing to step 4:
631 can be fit into 2297 3 times, resulting in a remainder of 404.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 1893 from 2297, we get 404.
Fetch the next digit (2) from the dividend, attach it to 404 and continue: 4042 / 631

Advancing to step 5:
631 goes into 4042 6 times with a remainder of 256.
Write down 6 as next digit of the result. 
Result so far: 136.0
Deduct 3786 from 4042 and we're left with 256.
Grab the next digit (0) from the dividend, add it to 256, then carry on: 2560 / 631

On to step 6:
2560 divided by 631 is 4 with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 1364.0
The remainder is 36 after subtracting 2524 from 2560.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 631

Going ahead to step 7:
The number 631 fits into 361 0 times, leaving a remainder of 361.
The number 0 becomes the next digit in our result. 
Result so far: 13640.0
If we subtract 0 from 361, we get 361.
Grab the next digit (2) from the dividend, add it to 361, then carry on: 3612 / 631

Step 8:
631 goes into 3612 5 times with a remainder of 457.
Use 5 as the next digit of our solution. 
Result so far: 136405.0
Deduct 3155 from 3612 and we're left with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Going ahead to step 9:
When dividing 4570 by 631, we get 7 with a remainder of 153.
The number 7 becomes the next digit in our result. 
Result so far: 136405.7
If we take 4417 away from 4570, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Advancing to step 10:
If we divide 1530 by 631, we get 2 and a remainder of 268.
The number 2 becomes the next digit in our result. 
Result so far: 136405.72
Deduct 1262 from 1530 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 11:
If we divide 2680 by 631, we get 4 and a remainder of 156.
Put 4 as the next digit of the answer. 
Result so far: 136405.724
If we take 2524 away from 2680, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 12:
When dividing 1560 by 631, we get 2 with a remainder of 298.
Put 2 as the next digit of the answer. 
Result so far: 136405.7242
If we take 1262 away from 1560, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 13:
631 can be fit into 2980 4 times, resulting in a remainder of 456.
The next digit of our result is 4. 
Result so far: 136405.72424
Deduct 2524 from 2980 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 14:
631 can be fit into 4560 7 times, resulting in a remainder of 143.
Record the quotient 7 as the next digit in the result. 
Result so far: 136405.724247
If we take 4417 away from 4560, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 15:
631 goes into 1430 2 times with a remainder of 168.
The number 2 becomes the next digit in our result. 
Result so far: 136405.7242472
If we subtract 1262 from 1430, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 16:
The number 631 fits into 1680 2 times, leaving a remainder of 418.
Put 2 as the next digit of the answer. 
Result so far: 136405.72424722
Deduct 1262 from 1680 and we're left with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

After the division, we end up with 136405.72424722 and a remainder of 4.18e-07.
