Let's divide 15508317 by 66
We want to figure out the number of times 15508317 can be divided by 66.

Moving on to step 1:
When dividing 1 by 66, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 66

Moving on to step 2:
If we divide 15 by 66, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 66

On to step 3:
155 divided by 66 is 2 with a remainder of 23.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 132 from 155 leaves us with 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 66

Moving on to step 4:
When dividing 230 by 66, we get 3 with a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 23.0
Deduct 198 from 230 and we're left with 32.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 66

Step 5:
If we divide 328 by 66, we get 4 and a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 234.0
If we subtract 264 from 328, we get 64.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 66

Moving on to step 6:
66 can be fit into 643 9 times, resulting in a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 2349.0
Deduct 594 from 643 and we're left with 49.
Append the next digit (1) from the dividend to 49 and continue with: 491 / 66

Going ahead to step 7:
When dividing 491 by 66, we get 7 with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 23497.0
Subtract 462 from 491 to get 29.
Append the next digit (7) from the dividend to 29 and continue with: 297 / 66

Moving on to step 8:
66 goes into 297 4 times with a remainder of 33.
Write down 4 as next digit of the result. 
Result so far: 234974.0
Subtract 264 from 297 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
66 can be fit into 330 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 234974.5
Subtract 330 from 330 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
The number 66 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 234974.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
0 divided by 66 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 234974.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 234974.5 with a remaining 0.0.
