135444 divided by 99 
We're looking to find how many times 99 goes into 135444.

Going ahead to step 1:
1 divided by 99 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 99

On to step 2:
99 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 99

Moving on to step 3:
135 divided by 99 is 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 99 from 135 to get 36.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 99

Advancing to step 4:
If we divide 364 by 99, we get 3 and a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 297 away from 364, we end up with 67.
Grab the next digit (4) from the dividend, add it to 67, then carry on: 674 / 99

Step 5:
99 goes into 674 6 times with a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 136.0
Deduct 594 from 674 and we're left with 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 99

On to step 6:
99 goes into 804 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 1368.0
If we subtract 792 from 804, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
99 goes into 120 1 times with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1368.1
The remainder is 21 after subtracting 99 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 8:
If we divide 210 by 99, we get 2 and a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 1368.12
Subtract 198 from 210 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
When dividing 120 by 99, we get 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1368.121
If we take 99 away from 120, we end up 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.

Going ahead to step 10:
210 divided by 99 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 1368.1212
If we take 198 away from 210, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
When dividing 120 by 99, we get 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1368.12121
Deduct 99 from 120 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.

Step 12:
If we divide 210 by 99, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 1368.121212
Subtract 198 from 210 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
99 goes into 120 1 times with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1368.1212121
If we take 99 away from 120, we end up 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.

Advancing to step 14:
99 goes into 210 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 1368.12121212
Deduct 198 from 210 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 1368.12121212 with a remainder of 1.2e-08.
