We're dividing 86631092 by 605 
We want to figure out the number of times 86631092 can be divided by 605.

On to step 1:
8 divided by 605 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 605

On to step 2:
86 divided by 605 is 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (6) from the dividend, attach it to 86 and continue: 866 / 605

Going ahead to step 3:
The number 605 fits into 866 1 times, leaving a remainder of 261.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 605 from 866, we get 261.
Include the next digit (3) from the dividend after 261, then repeat: 2613 / 605

Going ahead to step 4:
When dividing 2613 by 605, we get 4 with a remainder of 193.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 193 after subtracting 2420 from 2613.
Take the next digit (1) from the dividend and append it to 193, then repeat: 1931 / 605

Let's proceed to step 5:
The number 605 fits into 1931 3 times, leaving a remainder of 116.
The number 3 becomes the next digit in our result. 
Result so far: 143.0
If we take 1815 away from 1931, we end up with 116.
Take the next digit (0) from the dividend and append it to 116, then repeat: 1160 / 605

Step 6:
If we divide 1160 by 605, we get 1 and a remainder of 555.
The number 1 becomes the next digit in our result. 
Result so far: 1431.0
Subtract 605 from 1160 to get 555.
Take the next digit (9) from the dividend and append it to 555, then repeat: 5559 / 605

Going ahead to step 7:
If we divide 5559 by 605, we get 9 and a remainder of 114.
The next digit of our result is 9. 
Result so far: 14319.0
If we take 5445 away from 5559, we end up with 114.
Grab the next digit (2) from the dividend, add it to 114, then carry on: 1142 / 605

Advancing to step 8:
1142 divided by 605 is 1 with a remainder of 537.
Put 1 as the next digit of the answer. 
Result so far: 143191.0
If we take 605 away from 1142, we end up with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

On to step 9:
605 can be fit into 5370 8 times, resulting in a remainder of 530.
Put 8 as the next digit of the answer. 
Result so far: 143191.8
If we subtract 4840 from 5370, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 10:
605 goes into 5300 8 times with a remainder of 460.
Put 8 as the next digit of the answer. 
Result so far: 143191.88
If we take 4840 away from 5300, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Our division results in 143191.88 with a remaining 0.46.
