71508251 ÷ 631 
Our goal is to divide 71508251 by 631.

On to step 1:
7 divided by 631 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 631

On to step 2:
631 goes into 71 0 times with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Append the next digit (5) from the dividend to 71 and continue with: 715 / 631

Step 3:
631 can be fit into 715 1 times, resulting in a remainder of 84.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 631 from 715 and we're left with 84.
Include the next digit (0) from the dividend after 84, then repeat: 840 / 631

Let's proceed to step 4:
631 can be fit into 840 1 times, resulting in a remainder of 209.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 209 after subtracting 631 from 840.
Append the next digit (8) from the dividend to 209 and continue with: 2098 / 631

Going ahead to step 5:
When dividing 2098 by 631, we get 3 with a remainder of 205.
Use 3 as the next digit of our solution. 
Result so far: 113.0
If we take 1893 away from 2098, we end up with 205.
Grab the next digit (2) from the dividend, add it to 205, then carry on: 2052 / 631

Let's proceed to step 6:
If we divide 2052 by 631, we get 3 and a remainder of 159.
Put 3 as the next digit of the answer. 
Result so far: 1133.0
Subtract 1893 from 2052 to get 159.
Include the next digit (5) from the dividend after 159, then repeat: 1595 / 631

Step 7:
The number 631 fits into 1595 2 times, leaving a remainder of 333.
Use 2 as the next digit of our solution. 
Result so far: 11332.0
The remainder is 333 after subtracting 1262 from 1595.
Include the next digit (1) from the dividend after 333, then repeat: 3331 / 631

Step 8:
3331 divided by 631 is 5 with a remainder of 176.
Use 5 as the next digit of our solution. 
Result so far: 113325.0
If we subtract 3155 from 3331, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 9:
If we divide 1760 by 631, we get 2 and a remainder of 498.
Put 2 as the next digit of the answer. 
Result so far: 113325.2
If we subtract 1262 from 1760, we get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Let's proceed to step 10:
The number 631 fits into 4980 7 times, leaving a remainder of 563.
Put 7 as the next digit of the answer. 
Result so far: 113325.27
Subtract 4417 from 4980 to get 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

On to step 11:
631 goes into 5630 8 times with a remainder of 582.
The next digit of our result is 8. 
Result so far: 113325.278
Subtracting 5048 from 5630 leaves us with 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Moving on to step 12:
When dividing 5820 by 631, we get 9 with a remainder of 141.
Write down 9 as next digit of the result. 
Result so far: 113325.2789
If we take 5679 away from 5820, we end up with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 13:
The number 631 fits into 1410 2 times, leaving a remainder of 148.
Record the quotient 2 as the next digit in the result. 
Result so far: 113325.27892
Subtracting 1262 from 1410 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 14:
If we divide 1480 by 631, we get 2 and a remainder of 218.
Record the quotient 2 as the next digit in the result. 
Result so far: 113325.278922
Subtract 1262 from 1480 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

The final result is 113325.278922 with a remainder of 2.18e-05.
