We're dividing 936409 by 86 
We're looking to find how many times 86 goes into 936409.

On to 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
If we take 0 away from 9, we end up with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 86

Advancing to step 2:
93 divided by 86 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 86 from 93 and we're left with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 86

Step 3:
If we divide 76 by 86, we get 0 and a remainder of 76.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 76, we end up with 76.
Include the next digit (4) from the dividend after 76, then repeat: 764 / 86

Step 4:
When dividing 764 by 86, we get 8 with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
Deduct 688 from 764 and we're left with 76.
Bring next digit (0) of the dividend behind the 76 and repeat the process: 760 / 86

Moving on to step 5:
86 can be fit into 760 8 times, resulting in a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 1088.0
If we subtract 688 from 760, we get 72.
Append the next digit (9) from the dividend to 72 and continue with: 729 / 86

Advancing to step 6:
729 divided by 86 is 8 with a remainder of 41.
Write down 8 as next digit of the result. 
Result so far: 10888.0
Deduct 688 from 729 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
The number 86 fits into 410 4 times, leaving a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 10888.4
Deduct 344 from 410 and we're left 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.

Let's proceed to step 8:
When dividing 660 by 86, we get 7 with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 10888.47
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.

Advancing to step 9:
If we divide 580 by 86, we get 6 and a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 10888.476
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.

Moving on to step 10:
When dividing 640 by 86, we get 7 with a remainder of 38.
The next digit of our result is 7. 
Result so far: 10888.4767
Subtract 602 from 640 to 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.

Moving on to step 11:
If we divide 380 by 86, we get 4 and a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 10888.47674
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
If we divide 360 by 86, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 10888.476744
If we take 344 away from 360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 10888.476744 with a balance of 1.6e-06.
