We look at the division of 2979 by 51 
Our goal is to divide 2979 by 51.

Step 1:
If we divide 2 by 51, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 51

Step 2:
The number 51 fits into 29 0 times, leaving a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Fetch the next digit (7) from the dividend, attach it to 29 and continue: 297 / 51

Let's proceed to step 3:
297 divided by 51 is 5 with a remainder of 42.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 42 after subtracting 255 from 297.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 51

Advancing to step 4:
429 divided by 51 is 8 with a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Subtracting 408 from 429 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 5:
The number 51 fits into 210 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 58.4
If we take 204 away from 210, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 6:
60 divided by 51 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 58.41
If we take 51 away from 60, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
51 can be fit into 90 1 times, resulting in a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 58.411
Subtract 51 from 90 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 58.411 and a remainder of 0.0039.
