Let's divide 77160 by 91
Let's see how many times 91 fits into 77160.

Step 1:
91 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 91

Going ahead to step 2:
77 divided by 91 is 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Include the next digit (1) from the dividend after 77, then repeat: 771 / 91

Let's proceed to step 3:
The number 91 fits into 771 8 times, leaving a remainder of 43.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 728 from 771 leaves us with 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 91

On to step 4:
91 can be fit into 436 4 times, resulting in a remainder of 72.
The next digit of our result is 4. 
Result so far: 84.0
Deduct 364 from 436 and we're left with 72.
Bring next digit (0) of the dividend behind the 72 and repeat the process: 720 / 91

Step 5:
91 can be fit into 720 7 times, resulting in a remainder of 83.
The next digit of our result is 7. 
Result so far: 847.0
The remainder is 83 after subtracting 637 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 6:
When dividing 830 by 91, we get 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 847.9
Subtracting 819 from 830 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
110 divided by 91 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 847.91
If we subtract 91 from 110, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
If we divide 190 by 91, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 847.912
Subtracting 182 from 190 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
When dividing 80 by 91, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 847.912
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
When dividing 800 by 91, we get 8 with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 847.91208
The remainder is 72 after subtracting 728 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
If we divide 720 by 91, we get 7 and a remainder of 83.
The next digit of our result is 7. 
Result so far: 847.912087
Deduct 637 from 720 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 12:
91 can be fit into 830 9 times, resulting in a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 847.9120879
Subtract 819 from 830 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 13:
When dividing 110 by 91, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 847.91208791
The remainder is 19 after subtracting 91 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

In conclusion, the division gives 847.91208791 with a balance of 1.9e-08.
