We look at the division of 315135 by 28 
We want to figure out the number of times 315135 can be divided by 28.

Going ahead to step 1:
3 divided by 28 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 28

Advancing to step 2:
If we divide 31 by 28, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 3 after subtracting 28 from 31.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 28

On to step 3:
When dividing 35 by 28, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 11.0
If we take 28 away from 35, we end up with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 28

Advancing to step 4:
The number 28 fits into 71 2 times, leaving a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 112.0
If we take 56 away from 71, we end up with 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 28

Moving on to step 5:
28 goes into 153 5 times with a remainder of 13.
The next digit of our result is 5. 
Result so far: 1125.0
The remainder is 13 after subtracting 140 from 153.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 28

Going ahead to step 6:
28 goes into 135 4 times with a remainder of 23.
The number 4 becomes the next digit in our result. 
Result so far: 11254.0
Deduct 112 from 135 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
230 divided by 28 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 11254.8
If we take 224 away from 230, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
If we divide 60 by 28, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 11254.82
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
If we divide 40 by 28, we get 1 and a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 11254.821
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
28 goes into 120 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 11254.8214
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
If we divide 80 by 28, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 11254.82142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 11254.821428
If we subtract 224 from 240, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 11254.8214285
If we take 140 away from 160, we end up 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.

On to step 14:
200 divided by 28 is 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 11254.82142857
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 11254.82142857 with a balance of 4e-09.
