Let's divide 28122491 by 857
Our goal is to divide 28122491 by 857.

Going ahead to step 1:
2 divided by 857 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
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 / 857

Advancing to step 2:
When dividing 28 by 857, we get 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 857

On to step 3:
When dividing 281 by 857, we get 0 with a remainder of 281.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 281 after subtracting 0 from 281.
Fetch the next digit (2) from the dividend, attach it to 281 and continue: 2812 / 857

Advancing to step 4:
857 can be fit into 2812 3 times, resulting in a remainder of 241.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 241 after subtracting 2571 from 2812.
Include the next digit (2) from the dividend after 241, then repeat: 2412 / 857

Step 5:
2412 divided by 857 is 2 with a remainder of 698.
Write down 2 as next digit of the result. 
Result so far: 32.0
Deduct 1714 from 2412 and we're left with 698.
Fetch the next digit (4) from the dividend, attach it to 698 and continue: 6984 / 857

Step 6:
857 goes into 6984 8 times with a remainder of 128.
Put 8 as the next digit of the answer. 
Result so far: 328.0
Deduct 6856 from 6984 and we're left with 128.
Take the next digit (9) from the dividend and append it to 128, then repeat: 1289 / 857

On to step 7:
If we divide 1289 by 857, we get 1 and a remainder of 432.
The next digit of our result is 1. 
Result so far: 3281.0
If we take 857 away from 1289, we end up with 432.
Include the next digit (1) from the dividend after 432, then repeat: 4321 / 857

On to step 8:
When dividing 4321 by 857, we get 5 with a remainder of 36.
The number 5 becomes the next digit in our result. 
Result so far: 32815.0
Subtracting 4285 from 4321 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
When dividing 360 by 857, we get 0 with a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 32815.0
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 10:
3600 divided by 857 is 4 with a remainder of 172.
The number 4 becomes the next digit in our result. 
Result so far: 32815.04
Subtracting 3428 from 3600 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 11:
When dividing 1720 by 857, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 32815.042
Subtract 1714 from 1720 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
The number 857 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 32815.042
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 13:
600 divided by 857 is 0 with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 32815.042
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final result is 32815.042 with a remainder of 0.0006.
