963393 divided by 86 
We want to figure out the number of times 963393 can be divided by 86.

On to step 1:
86 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 86

On to step 2:
If we divide 96 by 86, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 86 from 96 to get 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 86

On to step 3:
103 divided by 86 is 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 86 from 103, we get 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 86

Let's proceed to step 4:
173 divided by 86 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 112.0
If we take 172 away from 173, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 86

Moving on to step 5:
86 goes into 19 0 times with a remainder of 19.
The next digit of our result is 0. 
Result so far: 1120.0
The remainder is 19 after subtracting 0 from 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 86

Step 6:
The number 86 fits into 193 2 times, leaving a remainder of 21.
The next digit of our result is 2. 
Result so far: 11202.0
If we take 172 away from 193, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
210 divided by 86 is 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 11202.2
If we take 172 away from 210, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
When dividing 380 by 86, we get 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 11202.24
Subtracting 344 from 380 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
If we divide 360 by 86, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 11202.244
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 11202.244 with a remainder of 0.0016.
