We're dividing 389219 by 28 
We want to figure out the number of times 389219 can be divided by 28.

On to step 1:
The number 28 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 28

On to step 2:
28 goes into 38 1 times with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 28 from 38, we get 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 28

Let's proceed to step 3:
28 goes into 109 3 times with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 84 from 109, we get 25.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 28

On to step 4:
The number 28 fits into 252 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 139.0
The remainder is 0 after subtracting 252 from 252.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 28

On to step 5:
When dividing 1 by 28, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 1390.0
Subtract 0 from 1 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 28

Advancing to step 6:
When dividing 19 by 28, we get 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 13900.0
Subtract 0 from 19 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
28 can be fit into 190 6 times, resulting in a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 13900.6
Deduct 168 from 190 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
220 divided by 28 is 7 with a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 13900.67
Subtracting 196 from 220 leaves us 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.

Let's proceed to step 9:
When dividing 240 by 28, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 13900.678
Subtracting 224 from 240 leaves us with 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 10:
If we divide 160 by 28, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 13900.6785
Subtracting 140 from 160 leaves us 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.

Step 11:
When dividing 200 by 28, we get 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 13900.67857
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
28 goes into 40 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 13900.678571
Subtract 28 from 40 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.

On to step 13:
If we divide 120 by 28, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 13900.6785714
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.

Step 14:
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: 13900.67857142
If we subtract 56 from 80, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 13900.67857142 with a remainder of 2.4e-08.
