Let's divide 780020 by 91
We want to figure out the number of times 780020 can be divided by 91.

Advancing to step 1:
91 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 91

Let's proceed to step 2:
If we divide 78 by 91, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Include the next digit (0) from the dividend after 78, then repeat: 780 / 91

Advancing to step 3:
91 goes into 780 8 times with a remainder of 52.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 728 from 780 to get 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 91

Let's proceed to step 4:
When dividing 520 by 91, we get 5 with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 85.0
Subtract 455 from 520 to get 65.
Include the next digit (2) from the dividend after 65, then repeat: 652 / 91

Moving on to step 5:
The number 91 fits into 652 7 times, leaving a remainder of 15.
The next digit of our result is 7. 
Result so far: 857.0
If we take 637 away from 652, we end up with 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 91

Going ahead to step 6:
150 divided by 91 is 1 with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 8571.0
Subtract 91 from 150 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 7:
91 goes into 590 6 times with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 8571.6
Subtracting 546 from 590 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
If we divide 440 by 91, we get 4 and a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 8571.64
The remainder is 76 after subtracting 364 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 9:
When dividing 760 by 91, we get 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 8571.648
If we subtract 728 from 760, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
If we divide 320 by 91, we get 3 and a remainder of 47.
The next digit of our result is 3. 
Result so far: 8571.6483
If we subtract 273 from 320, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 11:
91 goes into 470 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 8571.64835
Subtracting 455 from 470 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 12:
150 divided by 91 is 1 with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 8571.648351
If we take 91 away from 150, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 13:
If we divide 590 by 91, we get 6 and a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 8571.6483516
Subtracting 546 from 590 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 14:
If we divide 440 by 91, we get 4 and a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 8571.64835164
Subtracting 364 from 440 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

In conclusion, the division gives 8571.64835164 with a balance of 7.6e-08.
