Let's divide 789543 by 28
Let's see how many times 28 fits into 789543.

Going ahead to step 1:
7 divided by 28 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 28

Advancing to step 2:
78 divided by 28 is 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 56 from 78 to get 22.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 28

Step 3:
28 can be fit into 229 8 times, resulting in a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 224 from 229 and we're left with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 28

Moving on to step 4:
If we divide 55 by 28, we get 1 and a remainder of 27.
The next digit of our result is 1. 
Result so far: 281.0
If we take 28 away from 55, we end up with 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 28

Advancing to step 5:
If we divide 274 by 28, we get 9 and a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 2819.0
The remainder is 22 after subtracting 252 from 274.
Append the next digit (3) from the dividend to 22 and continue with: 223 / 28

Going ahead to step 6:
223 divided by 28 is 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 28197.0
If we subtract 196 from 223, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
270 divided by 28 is 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 28197.9
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.

Moving on to step 8:
28 goes into 180 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 28197.96
If we take 168 away from 180, 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.

On to step 9:
28 goes into 120 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 28197.964
If we take 112 away from 120, we end up 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 10:
When dividing 80 by 28, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 28197.9642
Subtracting 56 from 80 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.

Going ahead to step 11:
The number 28 fits into 240 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 28197.96428
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.

On to step 12:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 28197.964285
Subtract 140 from 160 to 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.

Going ahead to step 13:
28 goes into 200 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 28197.9642857
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.

Moving on to step 14:
If we divide 40 by 28, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 28197.96428571
If we subtract 28 from 40, we 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.

After the division, we end up with 28197.96428571 and a remainder of 1.2e-08.
