We're dividing 868938 by 51 
We want to divide 868938 by 51.

Going ahead to step 1:
If we divide 8 by 51, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 51

Going ahead to step 2:
51 goes into 86 1 times with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 51 away from 86, we end up with 35.
Include the next digit (8) from the dividend after 35, then repeat: 358 / 51

Step 3:
51 can be fit into 358 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 357 from 358 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 51

Moving on to step 4:
51 goes into 19 0 times with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 170.0
Deduct 0 from 19 and we're left with 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 51

Moving on to step 5:
51 goes into 193 3 times with a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 1703.0
Subtract 153 from 193 to get 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 51

Going ahead to step 6:
51 can be fit into 408 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 17038.0
If we subtract 408 from 408, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
When dividing 0 by 51, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17038.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
51 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17038.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 17038.0 with a remainder of 0.0.
