91566709 ÷ 791 
Our goal is to divide 91566709 by 791.

Let's proceed to step 1:
9 divided by 791 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 791

Going ahead to step 2:
791 goes into 91 0 times with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Grab the next digit (5) from the dividend, add it to 91, then carry on: 915 / 791

Step 3:
791 goes into 915 1 times with a remainder of 124.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 791 from 915 to get 124.
Bring next digit (6) of the dividend behind the 124 and repeat the process: 1246 / 791

Advancing to step 4:
When dividing 1246 by 791, we get 1 with a remainder of 455.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 791 from 1246 and we're left with 455.
Append the next digit (6) from the dividend to 455 and continue with: 4556 / 791

Advancing to step 5:
791 goes into 4556 5 times with a remainder of 601.
Use 5 as the next digit of our solution. 
Result so far: 115.0
Subtracting 3955 from 4556 leaves us with 601.
Include the next digit (7) from the dividend after 601, then repeat: 6017 / 791

On to step 6:
The number 791 fits into 6017 7 times, leaving a remainder of 480.
The number 7 becomes the next digit in our result. 
Result so far: 1157.0
Subtracting 5537 from 6017 leaves us with 480.
Take the next digit (0) from the dividend and append it to 480, then repeat: 4800 / 791

Advancing to step 7:
791 can be fit into 4800 6 times, resulting in a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 11576.0
Deduct 4746 from 4800 and we're left with 54.
Fetch the next digit (9) from the dividend, attach it to 54 and continue: 549 / 791

Advancing to step 8:
549 divided by 791 is 0 with a remainder of 549.
Use 0 as the next digit of our solution. 
Result so far: 115760.0
Deduct 0 from 549 and we're left with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Let's proceed to step 9:
When dividing 5490 by 791, we get 6 with a remainder of 744.
The next digit of our result is 6. 
Result so far: 115760.6
If we subtract 4746 from 5490, we get 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

On to step 10:
If we divide 7440 by 791, we get 9 and a remainder of 321.
Write down 9 as next digit of the result. 
Result so far: 115760.69
If we subtract 7119 from 7440, we get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Let's proceed to step 11:
791 can be fit into 3210 4 times, resulting in a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 115760.694
Deduct 3164 from 3210 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
460 divided by 791 is 0 with a remainder of 460.
Use 0 as the next digit of our solution. 
Result so far: 115760.694
Subtracting 0 from 460 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 13:
When dividing 4600 by 791, we get 5 with a remainder of 645.
Write down 5 as next digit of the result. 
Result so far: 115760.69405
Subtracting 3955 from 4600 leaves us with 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Let's proceed to step 14:
If we divide 6450 by 791, we get 8 and a remainder of 122.
The number 8 becomes the next digit in our result. 
Result so far: 115760.694058
If we subtract 6328 from 6450, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 15:
791 goes into 1220 1 times with a remainder of 429.
Write down 1 as next digit of the result. 
Result so far: 115760.6940581
Deduct 791 from 1220 and we're left with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Going ahead to step 16:
The number 791 fits into 4290 5 times, leaving a remainder of 335.
Put 5 as the next digit of the answer. 
Result so far: 115760.69405815
Deduct 3955 from 4290 and we're left with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

In conclusion, the division gives 115760.69405815 with a balance of 3.35e-07.
