We divide 42136 by 99
We want to figure out the number of times 42136 can be divided by 99.

On to step 1:
If we divide 4 by 99, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 99

Moving on to step 2:
99 goes into 42 0 times with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 99

Advancing to step 3:
If we divide 421 by 99, we get 4 and a remainder of 25.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 396 from 421 and we're left with 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 99

Moving on to step 4:
99 can be fit into 253 2 times, resulting in a remainder of 55.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
If we subtract 198 from 253, we get 55.
Include the next digit (6) from the dividend after 55, then repeat: 556 / 99

On to step 5:
The number 99 fits into 556 5 times, leaving a remainder of 61.
The number 5 becomes the next digit in our result. 
Result so far: 425.0
The remainder is 61 after subtracting 495 from 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 6:
99 goes into 610 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 425.6
The remainder is 16 after subtracting 594 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
160 divided by 99 is 1 with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 425.61
If we take 99 away from 160, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 8:
610 divided by 99 is 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 425.616
Deduct 594 from 610 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
99 goes into 160 1 times with a remainder of 61.
Write down 1 as next digit of the result. 
Result so far: 425.6161
The remainder is 61 after subtracting 99 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 10:
610 divided by 99 is 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 425.61616
Subtracting 594 from 610 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
When dividing 160 by 99, we get 1 with a remainder of 61.
Write down 1 as next digit of the result. 
Result so far: 425.616161
Deduct 99 from 160 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 12:
When dividing 610 by 99, we get 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 425.6161616
Deduct 594 from 610 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
160 divided by 99 is 1 with a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 425.61616161
If we subtract 99 from 160, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

After the division, we end up with 425.61616161 and a remainder of 6.1e-08.
