647652 divided by 51 
Our goal is to divide 647652 by 51.

Step 1:
When dividing 6 by 51, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 51

Moving on to step 2:
51 goes into 64 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 51 from 64 to get 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 51

Moving on to step 3:
The number 51 fits into 137 2 times, leaving a remainder of 35.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 102 from 137 to get 35.
Bring next digit (6) of the dividend behind the 35 and repeat the process: 356 / 51

Advancing to step 4:
When dividing 356 by 51, we get 6 with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
If we subtract 306 from 356, we get 50.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 51

On to step 5:
When dividing 505 by 51, we get 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 1269.0
The remainder is 46 after subtracting 459 from 505.
Include the next digit (2) from the dividend after 46, then repeat: 462 / 51

Advancing to step 6:
51 can be fit into 462 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 12699.0
If we subtract 459 from 462, we 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.

Step 7:
51 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 12699.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
300 divided by 51 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 12699.05
The remainder is 45 after subtracting 255 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 9:
The number 51 fits into 450 8 times, leaving a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 12699.058
Deduct 408 from 450 and we're left 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.

Going ahead to step 10:
If we divide 420 by 51, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 12699.0588
If we take 408 away from 420, we end up 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.

The final result is 12699.0588 with a remainder of 0.00012.
