We look at the division of 86636405 by 552 
We want to divide 86636405 by 552.

Step 1:
The number 552 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 552

Going ahead to step 2:
552 goes into 86 0 times with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Take the next digit (6) from the dividend and append it to 86, then repeat: 866 / 552

Step 3:
552 goes into 866 1 times with a remainder of 314.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 552 from 866 to get 314.
Include the next digit (3) from the dividend after 314, then repeat: 3143 / 552

Going ahead to step 4:
3143 divided by 552 is 5 with a remainder of 383.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 2760 from 3143 to get 383.
Append the next digit (6) from the dividend to 383 and continue with: 3836 / 552

Moving on to step 5:
552 can be fit into 3836 6 times, resulting in a remainder of 524.
The next digit of our result is 6. 
Result so far: 156.0
If we take 3312 away from 3836, we end up with 524.
Append the next digit (4) from the dividend to 524 and continue with: 5244 / 552

Moving on to step 6:
552 goes into 5244 9 times with a remainder of 276.
Record the quotient 9 as the next digit in the result. 
Result so far: 1569.0
Subtract 4968 from 5244 to get 276.
Fetch the next digit (0) from the dividend, attach it to 276 and continue: 2760 / 552

On to step 7:
2760 divided by 552 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 15695.0
If we subtract 2760 from 2760, we get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 552

Let's proceed to step 8:
552 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 156950.0
Deduct 0 from 5 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
The number 552 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 156950.0
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
If we divide 500 by 552, we get 0 and a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 156950.0
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

After the division, we end up with 156950.0 and a remainder of 0.5.
