We look at the division of 728058 by 51 
Let's see how many times 51 fits into 728058.

Going ahead to step 1:
If we divide 7 by 51, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 51

On to step 2:
51 can be fit into 72 1 times, resulting in a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 51 from 72 to get 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 51

Advancing to step 3:
51 can be fit into 218 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 204 from 218 leaves us with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 51

On to step 4:
If we divide 140 by 51, we get 2 and a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 142.0
Subtract 102 from 140 to get 38.
Fetch the next digit (5) from the dividend, attach it to 38 and continue: 385 / 51

On to step 5:
When dividing 385 by 51, we get 7 with a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 1427.0
Deduct 357 from 385 and we're left with 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 51

Step 6:
51 goes into 288 5 times with a remainder of 33.
The number 5 becomes the next digit in our result. 
Result so far: 14275.0
If we subtract 255 from 288, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
51 can be fit into 330 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 14275.6
If we take 306 away from 330, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
51 can be fit into 240 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 14275.64
If we subtract 204 from 240, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
When dividing 360 by 51, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 14275.647
If we take 357 away from 360, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
51 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 14275.647
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
51 can be fit into 300 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 14275.64705
If we subtract 255 from 300, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 12:
If we divide 450 by 51, we get 8 and a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 14275.647058
If we take 408 away from 450, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
51 goes into 420 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 14275.6470588
Subtracting 408 from 420 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 14275.6470588 and a remainder of 1.2e-07.
