Let's divide 42504289 by 135
We want to divide 42504289 by 135.

On to step 1:
When dividing 4 by 135, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 135

Going ahead to step 2:
135 can be fit into 42 0 times, resulting in a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 135

Moving on to step 3:
135 can be fit into 425 3 times, resulting in a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 20 after subtracting 405 from 425.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 135

On to step 4:
135 can be fit into 200 1 times, resulting in a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Deduct 135 from 200 and we're left with 65.
Append the next digit (4) from the dividend to 65 and continue with: 654 / 135

Step 5:
When dividing 654 by 135, we get 4 with a remainder of 114.
Put 4 as the next digit of the answer. 
Result so far: 314.0
Subtract 540 from 654 to get 114.
Take the next digit (2) from the dividend and append it to 114, then repeat: 1142 / 135

Step 6:
1142 divided by 135 is 8 with a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 3148.0
If we take 1080 away from 1142, we end up with 62.
Fetch the next digit (8) from the dividend, attach it to 62 and continue: 628 / 135

Let's proceed to step 7:
The number 135 fits into 628 4 times, leaving a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 31484.0
The remainder is 88 after subtracting 540 from 628.
Take the next digit (9) from the dividend and append it to 88, then repeat: 889 / 135

Advancing to step 8:
When dividing 889 by 135, we get 6 with a remainder of 79.
Record the quotient 6 as the next digit in the result. 
Result so far: 314846.0
Deduct 810 from 889 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 9:
790 divided by 135 is 5 with a remainder of 115.
The number 5 becomes the next digit in our result. 
Result so far: 314846.5
The remainder is 115 after subtracting 675 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 10:
135 can be fit into 1150 8 times, resulting in a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 314846.58
If we subtract 1080 from 1150, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 11:
700 divided by 135 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 314846.585
If we subtract 675 from 700, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 12:
When dividing 250 by 135, we get 1 with a remainder of 115.
The next digit of our result is 1. 
Result so far: 314846.5851
If we take 135 away from 250, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 13:
When dividing 1150 by 135, we get 8 with a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 314846.58518
Subtracting 1080 from 1150 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 14:
700 divided by 135 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 314846.585185
The remainder is 25 after subtracting 675 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 15:
The number 135 fits into 250 1 times, leaving a remainder of 115.
Put 1 as the next digit of the answer. 
Result so far: 314846.5851851
The remainder is 115 after subtracting 135 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 16:
135 goes into 1150 8 times with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 314846.58518518
Subtracting 1080 from 1150 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 314846.58518518 and a remainder of 7e-08.
