We look at the division of 578916 by 51 
Let's see how many times 51 fits into 578916.

On to step 1:
5 divided by 51 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 51

Moving on to step 2:
The number 51 fits into 57 1 times, leaving a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 51 from 57 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 51

On to step 3:
The number 51 fits into 68 1 times, leaving a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 17 after subtracting 51 from 68.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 51

Going ahead to step 4:
51 can be fit into 179 3 times, resulting in a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 113.0
The remainder is 26 after subtracting 153 from 179.
Include the next digit (1) from the dividend after 26, then repeat: 261 / 51

On to step 5:
51 can be fit into 261 5 times, resulting in a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 1135.0
If we subtract 255 from 261, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 51

Going ahead to step 6:
51 goes into 66 1 times with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 11351.0
If we subtract 51 from 66, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
The number 51 fits into 150 2 times, leaving a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 11351.2
Deduct 102 from 150 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 8:
If we divide 480 by 51, we get 9 and a remainder of 21.
The next digit of our result is 9. 
Result so far: 11351.29
Subtract 459 from 480 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 9:
210 divided by 51 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 11351.294
The remainder is 6 after subtracting 204 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
51 goes into 60 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 11351.2941
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 11:
If we divide 90 by 51, we get 1 and a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 11351.29411
Deduct 51 from 90 and we're left with 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 11351.29411 and a remainder of 3.9e-05.
