857912 divided by 51 
We want to divide 857912 by 51.

Advancing to step 1:
51 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 51

Moving on to step 2:
85 divided by 51 is 1 with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 51 away from 85, we end up with 34.
Append the next digit (7) from the dividend to 34 and continue with: 347 / 51

Moving on to step 3:
347 divided by 51 is 6 with a remainder of 41.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 306 from 347, we get 41.
Bring next digit (9) of the dividend behind the 41 and repeat the process: 419 / 51

Going ahead to step 4:
When dividing 419 by 51, we get 8 with a remainder of 11.
The next digit of our result is 8. 
Result so far: 168.0
Deduct 408 from 419 and we're left with 11.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 51

On to step 5:
The number 51 fits into 111 2 times, leaving a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 1682.0
If we take 102 away from 111, we end up with 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 51

Advancing to step 6:
51 can be fit into 92 1 times, resulting in a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 16821.0
Subtract 51 from 92 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 7:
51 goes into 410 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 16821.8
If we subtract 408 from 410, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
51 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 16821.8
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
200 divided by 51 is 3 with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 16821.803
If we subtract 153 from 200, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 10:
470 divided by 51 is 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 16821.8039
Subtract 459 from 470 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
If we divide 110 by 51, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 16821.80392
Subtracting 102 from 110 leaves us 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 12:
51 can be fit into 80 1 times, resulting in a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 16821.803921
If we take 51 away from 80, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 13:
51 goes into 290 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 16821.8039215
Subtract 255 from 290 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 14:
The number 51 fits into 350 6 times, leaving a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 16821.80392156
If we subtract 306 from 350, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 16821.80392156 with a remaining 4.4e-08.
