997591 divided by 86 
We're looking to find how many times 86 goes into 997591.

Let's proceed to step 1:
When dividing 9 by 86, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 86

Let's proceed to step 2:
The number 86 fits into 99 1 times, leaving a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 86 from 99 to get 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 86

On to step 3:
86 can be fit into 137 1 times, resulting in a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 86 from 137 to get 51.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 86

Going ahead to step 4:
When dividing 515 by 86, we get 5 with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
Subtracting 430 from 515 leaves us with 85.
Take the next digit (9) from the dividend and append it to 85, then repeat: 859 / 86

Advancing to step 5:
The number 86 fits into 859 9 times, leaving a remainder of 85.
Use 9 as the next digit of our solution. 
Result so far: 1159.0
Subtract 774 from 859 to get 85.
Append the next digit (1) from the dividend to 85 and continue with: 851 / 86

Advancing to step 6:
851 divided by 86 is 9 with a remainder of 77.
The number 9 becomes the next digit in our result. 
Result so far: 11599.0
If we take 774 away from 851, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 7:
If we divide 770 by 86, we get 8 and a remainder of 82.
The number 8 becomes the next digit in our result. 
Result so far: 11599.8
The remainder is 82 after subtracting 688 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 8:
86 goes into 820 9 times with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 11599.89
If we subtract 774 from 820, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
The number 86 fits into 460 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 11599.895
If we take 430 away from 460, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
If we divide 300 by 86, we get 3 and a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 11599.8953
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
86 can be fit into 420 4 times, resulting in a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 11599.89534
Subtract 344 from 420 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 12:
760 divided by 86 is 8 with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 11599.895348
If we take 688 away from 760, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
If we divide 720 by 86, we get 8 and a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 11599.8953488
Deduct 688 from 720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 11599.8953488, and the remainder is 3.2e-07.
