We divide 21577174 by 857
We want to divide 21577174 by 857.

Step 1:
The number 857 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 857

Going ahead to step 2:
21 divided by 857 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 857

On to step 3:
857 goes into 215 0 times with a remainder of 215.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 215, we end up with 215.
Include the next digit (7) from the dividend after 215, then repeat: 2157 / 857

Going ahead to step 4:
857 goes into 2157 2 times with a remainder of 443.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 443 after subtracting 1714 from 2157.
Fetch the next digit (7) from the dividend, attach it to 443 and continue: 4437 / 857

On to step 5:
4437 divided by 857 is 5 with a remainder of 152.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtracting 4285 from 4437 leaves us with 152.
Bring next digit (1) of the dividend behind the 152 and repeat the process: 1521 / 857

Going ahead to step 6:
The number 857 fits into 1521 1 times, leaving a remainder of 664.
The number 1 becomes the next digit in our result. 
Result so far: 251.0
If we subtract 857 from 1521, we get 664.
Take the next digit (7) from the dividend and append it to 664, then repeat: 6647 / 857

Advancing to step 7:
When dividing 6647 by 857, we get 7 with a remainder of 648.
Write down 7 as next digit of the result. 
Result so far: 2517.0
The remainder is 648 after subtracting 5999 from 6647.
Take the next digit (4) from the dividend and append it to 648, then repeat: 6484 / 857

On to step 8:
857 goes into 6484 7 times with a remainder of 485.
The next digit of our result is 7. 
Result so far: 25177.0
Subtract 5999 from 6484 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

On to step 9:
857 can be fit into 4850 5 times, resulting in a remainder of 565.
Use 5 as the next digit of our solution. 
Result so far: 25177.5
If we take 4285 away from 4850, we end up with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Advancing to step 10:
5650 divided by 857 is 6 with a remainder of 508.
The next digit of our result is 6. 
Result so far: 25177.56
If we subtract 5142 from 5650, we get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Step 11:
857 can be fit into 5080 5 times, resulting in a remainder of 795.
The next digit of our result is 5. 
Result so far: 25177.565
Subtract 4285 from 5080 to get 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

Moving on to step 12:
857 goes into 7950 9 times with a remainder of 237.
Use 9 as the next digit of our solution. 
Result so far: 25177.5659
If we subtract 7713 from 7950, we get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

On to step 13:
2370 divided by 857 is 2 with a remainder of 656.
Put 2 as the next digit of the answer. 
Result so far: 25177.56592
If we take 1714 away from 2370, we end up with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Advancing to step 14:
When dividing 6560 by 857, we get 7 with a remainder of 561.
The number 7 becomes the next digit in our result. 
Result so far: 25177.565927
If we subtract 5999 from 6560, we get 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Step 15:
If we divide 5610 by 857, we get 6 and a remainder of 468.
Use 6 as the next digit of our solution. 
Result so far: 25177.5659276
If we subtract 5142 from 5610, we get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Advancing to step 16:
The number 857 fits into 4680 5 times, leaving a remainder of 395.
Record the quotient 5 as the next digit in the result. 
Result so far: 25177.56592765
Subtracting 4285 from 4680 leaves us with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Our division results in 25177.56592765 with a remaining 3.95e-07.
