We look at the division of 78752297 by 31 
Our goal is to divide 78752297 by 31.

Let's proceed 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
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 31

Let's proceed to step 2:
31 goes into 78 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 16 after subtracting 62 from 78.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 31

On to step 3:
If we divide 167 by 31, we get 5 and a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 155 from 167 to get 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 31

On to step 4:
125 divided by 31 is 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 254.0
If we take 124 away from 125, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 31

Moving on to step 5:
The number 31 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 2540.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 31

Moving on to step 6:
The number 31 fits into 122 3 times, leaving a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 25403.0
Subtracting 93 from 122 leaves us with 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 31

Moving on to step 7:
If we divide 299 by 31, we get 9 and a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 254039.0
Subtract 279 from 299 to get 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 31

On to step 8:
31 goes into 207 6 times with a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 2540396.0
Deduct 186 from 207 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.

On to step 9:
When dividing 210 by 31, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 2540396.6
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.

Step 10:
31 can be fit into 240 7 times, resulting in a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 2540396.67
The remainder is 23 after subtracting 217 from 240.
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 11:
31 goes into 230 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 2540396.677
Subtracting 217 from 230 leaves us 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 2540396.677 with a remaining 0.0013.
