Let's divide 42709815 by 99
We want to divide 42709815 by 99.

Step 1:
4 divided by 99 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 99

On to step 2:
42 divided by 99 is 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (7) from the dividend after 42, then repeat: 427 / 99

On to step 3:
When dividing 427 by 99, we get 4 with a remainder of 31.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 396 from 427, we get 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 99

Going ahead to step 4:
If we divide 310 by 99, we get 3 and a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtract 297 from 310 to get 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 99

On to step 5:
If we divide 139 by 99, we get 1 and a remainder of 40.
The next digit of our result is 1. 
Result so far: 431.0
Subtracting 99 from 139 leaves us with 40.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 99

Going ahead to step 6:
If we divide 408 by 99, we get 4 and a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 4314.0
If we take 396 away from 408, we end up with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 99

Step 7:
The number 99 fits into 121 1 times, leaving a remainder of 22.
The next digit of our result is 1. 
Result so far: 43141.0
If we subtract 99 from 121, we get 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 99

Step 8:
If we divide 225 by 99, we get 2 and a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 431412.0
Deduct 198 from 225 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 9:
If we divide 270 by 99, we get 2 and a remainder of 72.
The next digit of our result is 2. 
Result so far: 431412.2
Deduct 198 from 270 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 10:
99 can be fit into 720 7 times, resulting in a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 431412.27
Subtracting 693 from 720 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 11:
270 divided by 99 is 2 with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 431412.272
If we subtract 198 from 270, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 12:
When dividing 720 by 99, we get 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 431412.2727
Subtract 693 from 720 to 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.

Step 13:
The number 99 fits into 270 2 times, leaving a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 431412.27272
Subtracting 198 from 270 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
99 goes into 720 7 times with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 431412.272727
If we subtract 693 from 720, 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 15:
When dividing 270 by 99, we get 2 with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 431412.2727272
Deduct 198 from 270 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 16:
When dividing 720 by 99, we get 7 with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 431412.27272727
Subtracting 693 from 720 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The quotient of the division is 431412.27272727, and the remainder is 2.7e-08.
