991142 divided by 86 
Our goal is to divide 991142 by 86.

Going ahead to step 1:
86 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 86

Going ahead to step 2:
86 can be fit into 99 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 86 from 99 leaves us with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 86

Moving on to step 3:
86 goes into 131 1 times with a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 86 away from 131, we end up with 45.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 86

Let's proceed to step 4:
If we divide 451 by 86, we get 5 and a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
Deduct 430 from 451 and we're left with 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 86

Going ahead to step 5:
86 goes into 214 2 times with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 1152.0
The remainder is 42 after subtracting 172 from 214.
Append the next digit (2) from the dividend to 42 and continue with: 422 / 86

Advancing to step 6:
The number 86 fits into 422 4 times, leaving a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 11524.0
Deduct 344 from 422 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 7:
The number 86 fits into 780 9 times, leaving a remainder of 6.
The next digit of our result is 9. 
Result so far: 11524.9
The remainder is 6 after subtracting 774 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
86 can be fit into 60 0 times, resulting in a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 11524.9
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
86 goes into 600 6 times with a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 11524.906
Subtracting 516 from 600 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 10:
When dividing 840 by 86, we get 9 with a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 11524.9069
If we take 774 away from 840, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 11:
660 divided by 86 is 7 with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 11524.90697
Subtracting 602 from 660 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 12:
When dividing 580 by 86, we get 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 11524.906976
Subtracting 516 from 580 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
86 goes into 640 7 times with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 11524.9069767
If we subtract 602 from 640, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 14:
86 can be fit into 380 4 times, resulting in a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 11524.90697674
The remainder is 36 after subtracting 344 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The quotient of the division is 11524.90697674, and the remainder is 3.6e-08.
