We look at the division of 28171517 by 389 
We want to divide 28171517 by 389.

Step 1:
389 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 389

Going ahead to step 2:
If we divide 28 by 389, we get 0 and a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 389

Step 3:
389 can be fit into 281 0 times, resulting in a remainder of 281.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 281 after subtracting 0 from 281.
Bring next digit (7) of the dividend behind the 281 and repeat the process: 2817 / 389

Going ahead to step 4:
When dividing 2817 by 389, we get 7 with a remainder of 94.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 2723 from 2817, we get 94.
Bring next digit (1) of the dividend behind the 94 and repeat the process: 941 / 389

Moving on to step 5:
The number 389 fits into 941 2 times, leaving a remainder of 163.
Put 2 as the next digit of the answer. 
Result so far: 72.0
If we take 778 away from 941, we end up with 163.
Take the next digit (5) from the dividend and append it to 163, then repeat: 1635 / 389

Step 6:
389 can be fit into 1635 4 times, resulting in a remainder of 79.
The number 4 becomes the next digit in our result. 
Result so far: 724.0
Subtracting 1556 from 1635 leaves us with 79.
Append the next digit (1) from the dividend to 79 and continue with: 791 / 389

On to step 7:
If we divide 791 by 389, we get 2 and a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 7242.0
If we take 778 away from 791, we end up with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 389

Moving on to step 8:
If we divide 137 by 389, we get 0 and a remainder of 137.
Write down 0 as next digit of the result. 
Result so far: 72420.0
Subtract 0 from 137 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Let's proceed to step 9:
If we divide 1370 by 389, we get 3 and a remainder of 203.
Record the quotient 3 as the next digit in the result. 
Result so far: 72420.3
Deduct 1167 from 1370 and we're left with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Step 10:
If we divide 2030 by 389, we get 5 and a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 72420.35
The remainder is 85 after subtracting 1945 from 2030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 11:
389 can be fit into 850 2 times, resulting in a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 72420.352
The remainder is 72 after subtracting 778 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 12:
720 divided by 389 is 1 with a remainder of 331.
Write down 1 as next digit of the result. 
Result so far: 72420.3521
Subtract 389 from 720 to get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

On to step 13:
The number 389 fits into 3310 8 times, leaving a remainder of 198.
Put 8 as the next digit of the answer. 
Result so far: 72420.35218
The remainder is 198 after subtracting 3112 from 3310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 14:
If we divide 1980 by 389, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 72420.352185
The remainder is 35 after subtracting 1945 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 15:
If we divide 350 by 389, we get 0 and a remainder of 350.
Write down 0 as next digit of the result. 
Result so far: 72420.352185
Deduct 0 from 350 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 16:
3500 divided by 389 is 8 with a remainder of 388.
Write down 8 as next digit of the result. 
Result so far: 72420.35218508
The remainder is 388 after subtracting 3112 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Our division results in 72420.35218508 with a remaining 3.88e-07.
