83880631 ÷ 99 
We want to figure out the number of times 83880631 can be divided by 99.

Moving on to step 1:
The number 99 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 99

Moving on to step 2:
If we divide 83 by 99, we get 0 and a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Include the next digit (8) from the dividend after 83, then repeat: 838 / 99

Let's proceed to step 3:
838 divided by 99 is 8 with a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 792 away from 838, we end up with 46.
Include the next digit (8) from the dividend after 46, then repeat: 468 / 99

Advancing to step 4:
99 goes into 468 4 times with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
If we subtract 396 from 468, we get 72.
Bring next digit (0) of the dividend behind the 72 and repeat the process: 720 / 99

On to step 5:
720 divided by 99 is 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 847.0
The remainder is 27 after subtracting 693 from 720.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 99

On to step 6:
99 goes into 276 2 times with a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 8472.0
Subtracting 198 from 276 leaves us with 78.
Take the next digit (3) from the dividend and append it to 78, then repeat: 783 / 99

Advancing to step 7:
If we divide 783 by 99, we get 7 and a remainder of 90.
The next digit of our result is 7. 
Result so far: 84727.0
Subtract 693 from 783 to get 90.
Fetch the next digit (1) from the dividend, attach it to 90 and continue: 901 / 99

Let's proceed to step 8:
When dividing 901 by 99, we get 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 847279.0
If we subtract 891 from 901, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
100 divided by 99 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 847279.1
If we take 99 away from 100, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
10 divided by 99 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 847279.1
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
The number 99 fits into 100 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 847279.101
Deduct 99 from 100 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
When dividing 10 by 99, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 847279.101
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
When dividing 100 by 99, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 847279.10101
Subtracting 99 from 100 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
The number 99 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 847279.10101
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 15:
If we divide 100 by 99, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 847279.1010101
The remainder is 1 after subtracting 99 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 16:
The number 99 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 847279.1010101
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 847279.1010101 with a balance of 1e-08.
