We're dividing 2126976 by 857 
We want to divide 2126976 by 857.

On to step 1:
The number 857 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 857

Going ahead to step 2:
If we divide 21 by 857, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 857

Step 3:
857 goes into 212 0 times with a remainder of 212.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 212 after subtracting 0 from 212.
Bring next digit (6) of the dividend behind the 212 and repeat the process: 2126 / 857

Let's proceed to step 4:
2126 divided by 857 is 2 with a remainder of 412.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1714 from 2126 leaves us with 412.
Append the next digit (9) from the dividend to 412 and continue with: 4129 / 857

Let's proceed to step 5:
The number 857 fits into 4129 4 times, leaving a remainder of 701.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Subtract 3428 from 4129 to get 701.
Grab the next digit (7) from the dividend, add it to 701, then carry on: 7017 / 857

Advancing to step 6:
When dividing 7017 by 857, we get 8 with a remainder of 161.
Write down 8 as next digit of the result. 
Result so far: 248.0
The remainder is 161 after subtracting 6856 from 7017.
Grab the next digit (6) from the dividend, add it to 161, then carry on: 1616 / 857

Advancing to step 7:
When dividing 1616 by 857, we get 1 with a remainder of 759.
Write down 1 as next digit of the result. 
Result so far: 2481.0
If we take 857 away from 1616, we end up with 759.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7590, and continue the process.

Going ahead to step 8:
If we divide 7590 by 857, we get 8 and a remainder of 734.
Put 8 as the next digit of the answer. 
Result so far: 2481.8
Deduct 6856 from 7590 and we're left with 734.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7340, and continue the process.

Going ahead to step 9:
857 goes into 7340 8 times with a remainder of 484.
Put 8 as the next digit of the answer. 
Result so far: 2481.88
Deduct 6856 from 7340 and we're left with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

The final result is 2481.88 with a remainder of 0.484.
