83639739 ÷ 31 
We want to divide 83639739 by 31.

Going ahead to step 1:
8 divided by 31 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 31

Step 2:
The number 31 fits into 83 2 times, leaving a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 62 away from 83, we end up with 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 31

Moving on to step 3:
When dividing 216 by 31, we get 6 with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 26.0
If we subtract 186 from 216, we get 30.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 31

Step 4:
31 can be fit into 303 9 times, resulting in a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 269.0
Subtracting 279 from 303 leaves us with 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 31

Moving on to step 5:
31 goes into 249 8 times with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 2698.0
The remainder is 1 after subtracting 248 from 249.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 31

Step 6:
If we divide 17 by 31, we get 0 and a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 26980.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 31

Going ahead to step 7:
173 divided by 31 is 5 with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 269805.0
If we take 155 away from 173, we end up with 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 31

Step 8:
31 goes into 189 6 times with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 2698056.0
Subtracting 186 from 189 leaves us 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 9:
31 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 2698056.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
When dividing 300 by 31, we get 9 with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 2698056.09
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 11:
The number 31 fits into 210 6 times, leaving a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 2698056.096
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 12:
The number 31 fits into 240 7 times, leaving a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 2698056.0967
If we take 217 away from 240, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 13:
31 can be fit into 230 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 2698056.09677
If we subtract 217 from 230, we 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.

In conclusion, the division gives 2698056.09677 with a balance of 1.3e-05.
