97920 ÷ 91 
Let's see how many times 91 fits into 97920.

Going ahead to step 1:
If we divide 9 by 91, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 91

Advancing to step 2:
97 divided by 91 is 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 91 from 97 and we're left with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 91

Moving on to step 3:
91 goes into 69 0 times with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 69, we end up with 69.
Take the next digit (2) from the dividend and append it to 69, then repeat: 692 / 91

Let's proceed to step 4:
91 goes into 692 7 times with a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
Deduct 637 from 692 and we're left with 55.
Fetch the next digit (0) from the dividend, attach it to 55 and continue: 550 / 91

Step 5:
When dividing 550 by 91, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 1076.0
The remainder is 4 after subtracting 546 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 6:
91 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1076.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
91 can be fit into 400 4 times, resulting in a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 1076.04
Subtracting 364 from 400 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
If we divide 360 by 91, we get 3 and a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 1076.043
If we subtract 273 from 360, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 9:
If we divide 870 by 91, we get 9 and a remainder of 51.
The next digit of our result is 9. 
Result so far: 1076.0439
Subtract 819 from 870 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 10:
510 divided by 91 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 1076.04395
If we subtract 455 from 510, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 11:
91 goes into 550 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 1076.043956
If we take 546 away from 550, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
The number 91 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1076.043956
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
91 goes into 400 4 times with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 1076.04395604
Subtract 364 from 400 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 1076.04395604 with a balance of 3.6e-08.
