We look at the division of 84270 by 28 
We're looking to find how many times 28 goes into 84270.

Going ahead to step 1:
When dividing 8 by 28, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 28

Let's proceed to step 2:
The number 28 fits into 84 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 84 from 84 to get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 28

Going ahead to step 3:
The number 28 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtract 0 from 2 to get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 28

Going ahead to step 4:
If we divide 27 by 28, we get 0 and a remainder of 27.
The next digit of our result is 0. 
Result so far: 300.0
The remainder is 27 after subtracting 0 from 27.
Bring next digit (0) of the dividend behind the 27 and repeat the process: 270 / 28

Going ahead to step 5:
28 goes into 270 9 times with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 3009.0
If we subtract 252 from 270, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 6:
180 divided by 28 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 3009.6
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
28 can be fit into 120 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 3009.64
Subtracting 112 from 120 leaves us with 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 8:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 3009.642
Deduct 56 from 80 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
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: 3009.6428
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.

Step 10:
If we divide 160 by 28, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 3009.64285
Deduct 140 from 160 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.

Going ahead to step 11:
200 divided by 28 is 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 3009.642857
Subtracting 196 from 200 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.

Going ahead to step 12:
40 divided by 28 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 3009.6428571
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.

Let's proceed to step 13:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 3009.64285714
Deduct 112 from 120 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 3009.64285714, with a leftover of 8e-09.
