We look at the division of 991297 by 86 
We want to figure out the number of times 991297 can be divided by 86.

Let's proceed to step 1:
If we divide 9 by 86, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 86

Moving on to step 2:
99 divided by 86 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 86 from 99 and we're left with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 86

Going ahead to step 3:
If we divide 131 by 86, we get 1 and a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 86 from 131 and we're left with 45.
Fetch the next digit (2) from the dividend, attach it to 45 and continue: 452 / 86

Moving on to step 4:
The number 86 fits into 452 5 times, leaving a remainder of 22.
The next digit of our result is 5. 
Result so far: 115.0
If we subtract 430 from 452, we get 22.
Append the next digit (9) from the dividend to 22 and continue with: 229 / 86

On to step 5:
The number 86 fits into 229 2 times, leaving a remainder of 57.
Put 2 as the next digit of the answer. 
Result so far: 1152.0
Deduct 172 from 229 and we're left with 57.
Include the next digit (7) from the dividend after 57, then repeat: 577 / 86

On to step 6:
When dividing 577 by 86, we get 6 with a remainder of 61.
Record the quotient 6 as the next digit in the result. 
Result so far: 11526.0
Subtracting 516 from 577 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 7:
When dividing 610 by 86, we get 7 with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 11526.7
The remainder is 8 after subtracting 602 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
If we divide 80 by 86, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 11526.7
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 9:
When dividing 800 by 86, we get 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 11526.709
If we take 774 away from 800, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
When dividing 260 by 86, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 11526.7093
If we take 258 away from 260, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
If we divide 20 by 86, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 11526.7093
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
When dividing 200 by 86, we get 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 11526.709302
Subtract 172 from 200 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
86 goes into 280 3 times with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 11526.7093023
Deduct 258 from 280 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
220 divided by 86 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 11526.70930232
Subtracting 172 from 220 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 11526.70930232 with a remainder of 4.8e-08.
