We look at the division of 393057 by 51 
We want to divide 393057 by 51.

Let's proceed to step 1:
3 divided by 51 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 51

Moving on to step 2:
51 can be fit into 39 0 times, resulting in a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 51

Moving on to step 3:
51 can be fit into 393 7 times, resulting in a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 357 away from 393, we end up with 36.
Grab the next digit (0) from the dividend, add it to 36, then carry on: 360 / 51

Let's proceed to step 4:
51 can be fit into 360 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 77.0
Subtracting 357 from 360 leaves us with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 51

Advancing to step 5:
If we divide 35 by 51, we get 0 and a remainder of 35.
The next digit of our result is 0. 
Result so far: 770.0
Deduct 0 from 35 and we're left with 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 51

Step 6:
51 can be fit into 357 7 times, resulting in a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 7707.0
If we subtract 357 from 357, 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.

Step 7:
0 divided by 51 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7707.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead 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: 7707.0
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.

Our division results in 7707.0 with a remaining 0.0.
