We're dividing 70023431 by 135 
We want to figure out the number of times 70023431 can be divided by 135.

Advancing to step 1:
135 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 135

Let's proceed to step 2:
135 can be fit into 70 0 times, resulting in a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Fetch the next digit (0) from the dividend, attach it to 70 and continue: 700 / 135

Going ahead to step 3:
When dividing 700 by 135, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 675 from 700 and we're left with 25.
Fetch the next digit (2) from the dividend, attach it to 25 and continue: 252 / 135

Step 4:
If we divide 252 by 135, we get 1 and a remainder of 117.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Deduct 135 from 252 and we're left with 117.
Grab the next digit (3) from the dividend, add it to 117, then carry on: 1173 / 135

Step 5:
When dividing 1173 by 135, we get 8 with a remainder of 93.
Record the quotient 8 as the next digit in the result. 
Result so far: 518.0
Subtracting 1080 from 1173 leaves us with 93.
Include the next digit (4) from the dividend after 93, then repeat: 934 / 135

Going ahead to step 6:
135 can be fit into 934 6 times, resulting in a remainder of 124.
Record the quotient 6 as the next digit in the result. 
Result so far: 5186.0
The remainder is 124 after subtracting 810 from 934.
Take the next digit (3) from the dividend and append it to 124, then repeat: 1243 / 135

Step 7:
The number 135 fits into 1243 9 times, leaving a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 51869.0
The remainder is 28 after subtracting 1215 from 1243.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 135

Going ahead to step 8:
If we divide 281 by 135, we get 2 and a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 518692.0
If we subtract 270 from 281, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
The number 135 fits into 110 0 times, leaving a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 518692.0
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
135 can be fit into 1100 8 times, resulting in a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 518692.08
The remainder is 20 after subtracting 1080 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
200 divided by 135 is 1 with a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 518692.081
If we subtract 135 from 200, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 12:
650 divided by 135 is 4 with a remainder of 110.
Put 4 as the next digit of the answer. 
Result so far: 518692.0814
Subtract 540 from 650 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 13:
1100 divided by 135 is 8 with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 518692.08148
Deduct 1080 from 1100 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
The number 135 fits into 200 1 times, leaving a remainder of 65.
The next digit of our result is 1. 
Result so far: 518692.081481
If we take 135 away from 200, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 15:
135 goes into 650 4 times with a remainder of 110.
The number 4 becomes the next digit in our result. 
Result so far: 518692.0814814
If we subtract 540 from 650, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 16:
The number 135 fits into 1100 8 times, leaving a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 518692.08148148
If we subtract 1080 from 1100, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 518692.08148148 with a remainder of 2e-08.
