917387 ÷ 86 
We want to divide 917387 by 86.

Step 1:
If we divide 9 by 86, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 86

Step 2:
The number 86 fits into 91 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 86 from 91 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 86

On to step 3:
86 goes into 57 0 times with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 57, we get 57.
Grab the next digit (3) from the dividend, add it to 57, then carry on: 573 / 86

Advancing to step 4:
86 can be fit into 573 6 times, resulting in a remainder of 57.
Write down 6 as next digit of the result. 
Result so far: 106.0
If we take 516 away from 573, we end up with 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 86

Let's proceed to step 5:
If we divide 578 by 86, we get 6 and a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 1066.0
Subtracting 516 from 578 leaves us with 62.
Include the next digit (7) from the dividend after 62, then repeat: 627 / 86

Step 6:
When dividing 627 by 86, we get 7 with a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 10667.0
Deduct 602 from 627 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
The number 86 fits into 250 2 times, leaving a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 10667.2
If we take 172 away from 250, we end up 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 8:
If we divide 780 by 86, we get 9 and a remainder of 6.
The next digit of our result is 9. 
Result so far: 10667.29
Subtracting 774 from 780 leaves us with 6.
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 9:
86 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 10667.29
If we take 0 away from 60, we end up 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 10:
86 can be fit into 600 6 times, resulting in a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 10667.2906
Subtract 516 from 600 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 11:
86 can be fit into 840 9 times, resulting in a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 10667.29069
The remainder is 66 after subtracting 774 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 12:
The number 86 fits into 660 7 times, leaving a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 10667.290697
The remainder is 58 after subtracting 602 from 660.
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 13:
The number 86 fits into 580 6 times, leaving a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 10667.2906976
If we take 516 away from 580, we end up 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.

Going ahead to step 14:
If we divide 640 by 86, we get 7 and a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 10667.29069767
The remainder is 38 after subtracting 602 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 10667.29069767, with a leftover of 3.8e-08.
