Step 1:
797 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 797

On to step 2:
When dividing 66 by 797, we get 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Append the next digit (8) from the dividend to 66 and continue with: 668 / 797

Moving on to step 3:
797 goes into 668 0 times with a remainder of 668.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 668, we end up with 668.
Take the next digit (1) from the dividend and append it to 668, then repeat: 6681 / 797

On to step 4:
The number 797 fits into 6681 8 times, leaving a remainder of 305.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 6376 from 6681 to get 305.
Append the next digit (7) from the dividend to 305 and continue with: 3057 / 797

Moving on to step 5:
If we divide 3057 by 797, we get 3 and a remainder of 666.
Write down 3 as next digit of the result. 
Result so far: 83.0
The remainder is 666 after subtracting 2391 from 3057.
Grab the next digit (9) from the dividend, add it to 666, then carry on: 6669 / 797

Advancing to step 6:
When dividing 6669 by 797, we get 8 with a remainder of 293.
Record the quotient 8 as the next digit in the result. 
Result so far: 838.0
Deduct 6376 from 6669 and we're left with 293.
Grab the next digit (1) from the dividend, add it to 293, then carry on: 2931 / 797

On to step 7:
2931 divided by 797 is 3 with a remainder of 540.
Use 3 as the next digit of our solution. 
Result so far: 8383.0
Deduct 2391 from 2931 and we're left with 540.
Include the next digit (7) from the dividend after 540, then repeat: 5407 / 797

Step 8:
797 goes into 5407 6 times with a remainder of 625.
Put 6 as the next digit of the answer. 
Result so far: 83836.0
The remainder is 625 after subtracting 4782 from 5407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Moving on to step 9:
When dividing 6250 by 797, we get 7 with a remainder of 671.
Record the quotient 7 as the next digit in the result. 
Result so far: 83836.7
The remainder is 671 after subtracting 5579 from 6250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

Let's proceed to step 10:
The number 797 fits into 6710 8 times, leaving a remainder of 334.
Use 8 as the next digit of our solution. 
Result so far: 83836.78
If we take 6376 away from 6710, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 11:
If we divide 3340 by 797, we get 4 and a remainder of 152.
Record the quotient 4 as the next digit in the result. 
Result so far: 83836.784
If we subtract 3188 from 3340, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 12:
1520 divided by 797 is 1 with a remainder of 723.
Record the quotient 1 as the next digit in the result. 
Result so far: 83836.7841
Deduct 797 from 1520 and we're left with 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Let's proceed to step 13:
797 goes into 7230 9 times with a remainder of 57.
The next digit of our result is 9. 
Result so far: 83836.78419
Subtract 7173 from 7230 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 14:
570 divided by 797 is 0 with a remainder of 570.
The number 0 becomes the next digit in our result. 
Result so far: 83836.78419
Subtract 0 from 570 to get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Let's proceed to step 15:
The number 797 fits into 5700 7 times, leaving a remainder of 121.
Use 7 as the next digit of our solution. 
Result so far: 83836.7841907
The remainder is 121 after subtracting 5579 from 5700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 16:
When dividing 1210 by 797, we get 1 with a remainder of 413.
The number 1 becomes the next digit in our result. 
Result so far: 83836.78419071
Subtract 797 from 1210 to get 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

In conclusion, the division gives 83836.78419071 with a balance of 4.13e-07.
