We look at the division of 315146 by 28 
We want to figure out the number of times 315146 can be divided by 28.

On to step 1:
28 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 28

Moving on to step 2:
28 goes into 31 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 3 after subtracting 28 from 31.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 28

Going ahead to step 3:
If we divide 35 by 28, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 28 from 35 leaves us with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 28

Moving on to step 4:
The number 28 fits into 71 2 times, leaving a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 112.0
If we subtract 56 from 71, we get 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 28

Moving on to step 5:
28 can be fit into 154 5 times, resulting in a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 1125.0
Subtracting 140 from 154 leaves us with 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 28

On to step 6:
146 divided by 28 is 5 with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 11255.0
Subtracting 140 from 146 leaves us 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.

Let's proceed to step 7:
When dividing 60 by 28, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 11255.2
If we take 56 away from 60, we end up 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.

Going ahead to step 8:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 11255.21
If we take 28 away from 40, 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.

Going ahead to step 9:
When dividing 120 by 28, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 11255.214
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.

On to step 10:
When dividing 80 by 28, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 11255.2142
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.

On to step 11:
28 can be fit into 240 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 11255.21428
Subtract 224 from 240 to 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.

Step 12:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 11255.214285
If we subtract 140 from 160, 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.

Advancing to step 13:
When dividing 200 by 28, we get 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 11255.2142857
Deduct 196 from 200 and we're left 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 14:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 11255.21428571
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.

Our division results in 11255.21428571 with a remaining 1.2e-08.
