We look at the division of 81987917 by 135 
Our goal is to divide 81987917 by 135.

Let's proceed to step 1:
8 divided by 135 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 135

Going ahead to step 2:
When dividing 81 by 135, we get 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (9) from the dividend after 81, then repeat: 819 / 135

Moving on to step 3:
819 divided by 135 is 6 with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 810 from 819 and we're left with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 135

On to step 4:
The number 135 fits into 98 0 times, leaving a remainder of 98.
Write down 0 as next digit of the result. 
Result so far: 60.0
If we subtract 0 from 98, we get 98.
Grab the next digit (7) from the dividend, add it to 98, then carry on: 987 / 135

Advancing to step 5:
The number 135 fits into 987 7 times, leaving a remainder of 42.
Put 7 as the next digit of the answer. 
Result so far: 607.0
Subtracting 945 from 987 leaves us with 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 135

Going ahead to step 6:
135 goes into 429 3 times with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 6073.0
The remainder is 24 after subtracting 405 from 429.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 135

Advancing to step 7:
135 can be fit into 241 1 times, resulting in a remainder of 106.
Put 1 as the next digit of the answer. 
Result so far: 60731.0
If we subtract 135 from 241, we get 106.
Grab the next digit (7) from the dividend, add it to 106, then carry on: 1067 / 135

Moving on to step 8:
135 can be fit into 1067 7 times, resulting in a remainder of 122.
Use 7 as the next digit of our solution. 
Result so far: 607317.0
If we take 945 away from 1067, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 9:
When dividing 1220 by 135, we get 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 607317.9
Subtract 1215 from 1220 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
If we divide 50 by 135, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 607317.9
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
135 can be fit into 500 3 times, resulting in a remainder of 95.
The next digit of our result is 3. 
Result so far: 607317.903
Subtracting 405 from 500 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 12:
950 divided by 135 is 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 607317.9037
If we take 945 away from 950, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
The number 135 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 607317.9037
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
135 goes into 500 3 times with a remainder of 95.
Put 3 as the next digit of the answer. 
Result so far: 607317.903703
Subtract 405 from 500 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 15:
When dividing 950 by 135, we get 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 607317.9037037
Subtract 945 from 950 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 16:
If we divide 50 by 135, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 607317.9037037
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 607317.9037037 and a remainder of 5e-08.
