71693510 divided by 31 
Our goal is to divide 71693510 by 31.

On to step 1:
31 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 31

Step 2:
71 divided by 31 is 2 with a remainder of 9.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 62 from 71 to get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 31

Going ahead to step 3:
If we divide 96 by 31, we get 3 and a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtract 93 from 96 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 31

Advancing to step 4:
When dividing 39 by 31, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 231.0
If we take 31 away from 39, we end up with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 31

On to step 5:
31 goes into 83 2 times with a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 2312.0
Subtracting 62 from 83 leaves us with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 31

Moving on to step 6:
The number 31 fits into 215 6 times, leaving a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 23126.0
Subtracting 186 from 215 leaves us with 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 31

Advancing to step 7:
31 goes into 291 9 times with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 231269.0
The remainder is 12 after subtracting 279 from 291.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 31

Moving on to step 8:
120 divided by 31 is 3 with a remainder of 27.
The next digit of our result is 3. 
Result so far: 2312693.0
If we subtract 93 from 120, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
When dividing 270 by 31, we get 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 2312693.8
If we take 248 away from 270, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
31 goes into 220 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 2312693.87
If we take 217 away from 220, 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.

Going ahead to step 11:
30 divided by 31 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 2312693.87
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
The number 31 fits into 300 9 times, leaving a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 2312693.8709
Deduct 279 from 300 and we're left 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.

Let's proceed to step 13:
When dividing 210 by 31, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 2312693.87096
Subtracting 186 from 210 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 14:
240 divided by 31 is 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 2312693.870967
Subtract 217 from 240 to get 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 15:
The number 31 fits into 230 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 2312693.8709677
If we take 217 away from 230, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 2312693.8709677 with a remaining 1.3e-07.
