We look at the division of 744515 by 51 
Our goal is to divide 744515 by 51.

Step 1:
When dividing 7 by 51, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 51

Step 2:
51 goes into 74 1 times with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 51 from 74, we get 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 51

Moving on to step 3:
The number 51 fits into 234 4 times, leaving a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 204 from 234 to get 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 51

On to step 4:
51 goes into 305 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 145.0
If we subtract 255 from 305, we get 50.
Append the next digit (1) from the dividend to 50 and continue with: 501 / 51

On to step 5:
If we divide 501 by 51, we get 9 and a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 1459.0
If we subtract 459 from 501, we get 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 51

On to step 6:
51 can be fit into 425 8 times, resulting in a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 14598.0
Deduct 408 from 425 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
The number 51 fits into 170 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 14598.3
The remainder is 17 after subtracting 153 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
170 divided by 51 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 14598.33
The remainder is 17 after subtracting 153 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 14598.33 with a remaining 0.017.
