We look at the division of 780051 by 91 
We're looking to find how many times 91 goes into 780051.

Moving on to step 1:
91 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 91

On to step 2:
The number 91 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Include the next digit (0) from the dividend after 78, then repeat: 780 / 91

On to step 3:
The number 91 fits into 780 8 times, leaving a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 728 away from 780, we end up with 52.
Bring next digit (0) of the dividend behind the 52 and repeat the process: 520 / 91

Going ahead to step 4:
520 divided by 91 is 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 85.0
If we take 455 away from 520, we end up with 65.
Grab the next digit (5) from the dividend, add it to 65, then carry on: 655 / 91

Let's proceed to step 5:
The number 91 fits into 655 7 times, leaving a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 857.0
The remainder is 18 after subtracting 637 from 655.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 91

Let's proceed to step 6:
When dividing 181 by 91, we get 1 with a remainder of 90.
Record the quotient 1 as the next digit in the result. 
Result so far: 8571.0
If we subtract 91 from 181, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 7:
91 goes into 900 9 times with a remainder of 81.
Record the quotient 9 as the next digit in the result. 
Result so far: 8571.9
Subtract 819 from 900 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 8:
The number 91 fits into 810 8 times, leaving a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 8571.98
Subtract 728 from 810 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 9:
91 can be fit into 820 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 8571.989
If we subtract 819 from 820, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
The number 91 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 8571.989
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
When dividing 100 by 91, we get 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 8571.98901
Subtracting 91 from 100 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 12:
91 can be fit into 90 0 times, resulting in a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 8571.98901
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 13:
91 can be fit into 900 9 times, resulting in a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 8571.9890109
Deduct 819 from 900 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 14:
91 goes into 810 8 times with a remainder of 82.
Use 8 as the next digit of our solution. 
Result so far: 8571.98901098
If we subtract 728 from 810, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

In conclusion, the division gives 8571.98901098 with a balance of 8.2e-08.
