797535 ÷ 51 
We're looking to find how many times 51 goes into 797535.

On to step 1:
7 divided by 51 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 51

Moving on to step 2:
The number 51 fits into 79 1 times, leaving a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 51 away from 79, we end up with 28.
Take the next digit (7) from the dividend and append it to 28, then repeat: 287 / 51

Going ahead to step 3:
The number 51 fits into 287 5 times, leaving a remainder of 32.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 255 away from 287, we end up with 32.
Bring next digit (5) of the dividend behind the 32 and repeat the process: 325 / 51

Moving on to step 4:
If we divide 325 by 51, we get 6 and a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
The remainder is 19 after subtracting 306 from 325.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 51

On to step 5:
When dividing 193 by 51, we get 3 with a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 1563.0
Subtracting 153 from 193 leaves us with 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 51

Advancing to step 6:
If we divide 405 by 51, we get 7 and a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 15637.0
The remainder is 48 after subtracting 357 from 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
480 divided by 51 is 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 15637.9
The remainder is 21 after subtracting 459 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 8:
51 can be fit into 210 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 15637.94
If we subtract 204 from 210, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
The number 51 fits into 60 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 15637.941
If we subtract 51 from 60, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
51 can be fit into 90 1 times, resulting in a remainder of 39.
The next digit of our result is 1. 
Result so far: 15637.9411
If we take 51 away from 90, we end up 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.

The final result is 15637.9411 with a remainder of 0.00039.
