We look at the division of 753561 by 51 
We want to figure out the number of times 753561 can be divided by 51.

Going ahead to step 1:
7 divided by 51 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 51

On to step 2:
If we divide 75 by 51, we get 1 and a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 51 from 75 leaves us with 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 51

Moving on to step 3:
When dividing 243 by 51, we get 4 with a remainder of 39.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 204 from 243 leaves us with 39.
Append the next digit (5) from the dividend to 39 and continue with: 395 / 51

Going ahead to step 4:
The number 51 fits into 395 7 times, leaving a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.0
Deduct 357 from 395 and we're left with 38.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 51

Moving on to step 5:
If we divide 386 by 51, we get 7 and a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 1477.0
If we subtract 357 from 386, we get 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 51

Let's proceed to step 6:
291 divided by 51 is 5 with a remainder of 36.
The next digit of our result is 5. 
Result so far: 14775.0
Subtracting 255 from 291 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
51 goes into 360 7 times with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 14775.7
Subtract 357 from 360 to get 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 8:
If we divide 30 by 51, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 14775.7
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.

On to step 9:
The number 51 fits into 300 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 14775.705
Subtract 255 from 300 to 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.

Step 10:
450 divided by 51 is 8 with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 14775.7058
Subtracting 408 from 450 leaves us 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.

Step 11:
420 divided by 51 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 14775.70588
Deduct 408 from 420 and we're left 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 14775.70588 and a remainder of 1.2e-05.
