We're dividing 86453214 by 936 
We want to divide 86453214 by 936.

Step 1:
8 divided by 936 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 936

Going ahead to step 2:
936 goes into 86 0 times with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Append the next digit (4) from the dividend to 86 and continue with: 864 / 936

Moving on to step 3:
If we divide 864 by 936, we get 0 and a remainder of 864.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 864 after subtracting 0 from 864.
Grab the next digit (5) from the dividend, add it to 864, then carry on: 8645 / 936

Step 4:
If we divide 8645 by 936, we get 9 and a remainder of 221.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 8424 away from 8645, we end up with 221.
Fetch the next digit (3) from the dividend, attach it to 221 and continue: 2213 / 936

Going ahead to step 5:
2213 divided by 936 is 2 with a remainder of 341.
Write down 2 as next digit of the result. 
Result so far: 92.0
Subtract 1872 from 2213 to get 341.
Append the next digit (2) from the dividend to 341 and continue with: 3412 / 936

Going ahead to step 6:
3412 divided by 936 is 3 with a remainder of 604.
Write down 3 as next digit of the result. 
Result so far: 923.0
Subtracting 2808 from 3412 leaves us with 604.
Append the next digit (1) from the dividend to 604 and continue with: 6041 / 936

Step 7:
If we divide 6041 by 936, we get 6 and a remainder of 425.
The number 6 becomes the next digit in our result. 
Result so far: 9236.0
Deduct 5616 from 6041 and we're left with 425.
Grab the next digit (4) from the dividend, add it to 425, then carry on: 4254 / 936

Step 8:
936 goes into 4254 4 times with a remainder of 510.
Use 4 as the next digit of our solution. 
Result so far: 92364.0
Subtract 3744 from 4254 to get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 9:
936 goes into 5100 5 times with a remainder of 420.
Put 5 as the next digit of the answer. 
Result so far: 92364.5
Subtracting 4680 from 5100 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 10:
When dividing 4200 by 936, we get 4 with a remainder of 456.
Write down 4 as next digit of the result. 
Result so far: 92364.54
Subtract 3744 from 4200 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

On to step 11:
936 can be fit into 4560 4 times, resulting in a remainder of 816.
Put 4 as the next digit of the answer. 
Result so far: 92364.544
If we subtract 3744 from 4560, we get 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

The final outcome is 92364.544, with a leftover of 0.0816.
