We're dividing 99648749 by 31 
Our goal is to divide 99648749 by 31.

On to step 1:
When dividing 9 by 31, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 31

On to step 2:
If we divide 99 by 31, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 93 from 99 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 31

Step 3:
66 divided by 31 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Subtracting 62 from 66 leaves us with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 31

Step 4:
44 divided by 31 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 321.0
If we take 31 away from 44, we end up with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 31

Let's proceed to step 5:
31 can be fit into 138 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 3214.0
Deduct 124 from 138 and we're left with 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 31

On to step 6:
If we divide 147 by 31, we get 4 and a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 32144.0
Deduct 124 from 147 and we're left with 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 31

Going ahead to step 7:
The number 31 fits into 234 7 times, leaving a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 321447.0
If we take 217 away from 234, we end up with 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 31

Moving on to step 8:
31 goes into 179 5 times with a remainder of 24.
Write down 5 as next digit of the result. 
Result so far: 3214475.0
If we subtract 155 from 179, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
31 goes into 240 7 times with a remainder of 23.
The next digit of our result is 7. 
Result so far: 3214475.7
If we subtract 217 from 240, we 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 10:
If we divide 230 by 31, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 3214475.77
Subtract 217 from 230 to get 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 3214475.77 with a remaining 0.013.
