We look at the division of 13660431 by 918 
We want to figure out the number of times 13660431 can be divided by 918.

Step 1:
If we divide 1 by 918, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 918

Going ahead to step 2:
918 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 918

Let's proceed to step 3:
If we divide 136 by 918, we get 0 and a remainder of 136.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 136, we get 136.
Append the next digit (6) from the dividend to 136 and continue with: 1366 / 918

Advancing to step 4:
When dividing 1366 by 918, we get 1 with a remainder of 448.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 918 from 1366 leaves us with 448.
Bring next digit (0) of the dividend behind the 448 and repeat the process: 4480 / 918

On to step 5:
When dividing 4480 by 918, we get 4 with a remainder of 808.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 3672 from 4480 and we're left with 808.
Bring next digit (4) of the dividend behind the 808 and repeat the process: 8084 / 918

On to step 6:
918 goes into 8084 8 times with a remainder of 740.
The number 8 becomes the next digit in our result. 
Result so far: 148.0
Deduct 7344 from 8084 and we're left with 740.
Include the next digit (3) from the dividend after 740, then repeat: 7403 / 918

Moving on to step 7:
When dividing 7403 by 918, we get 8 with a remainder of 59.
Use 8 as the next digit of our solution. 
Result so far: 1488.0
The remainder is 59 after subtracting 7344 from 7403.
Take the next digit (1) from the dividend and append it to 59, then repeat: 591 / 918

Advancing to step 8:
The number 918 fits into 591 0 times, leaving a remainder of 591.
The number 0 becomes the next digit in our result. 
Result so far: 14880.0
If we take 0 away from 591, we end up with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Moving on to step 9:
918 can be fit into 5910 6 times, resulting in a remainder of 402.
The next digit of our result is 6. 
Result so far: 14880.6
The remainder is 402 after subtracting 5508 from 5910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Step 10:
4020 divided by 918 is 4 with a remainder of 348.
Write down 4 as next digit of the result. 
Result so far: 14880.64
Deduct 3672 from 4020 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 11:
3480 divided by 918 is 3 with a remainder of 726.
Record the quotient 3 as the next digit in the result. 
Result so far: 14880.643
Subtracting 2754 from 3480 leaves us with 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Let's proceed to step 12:
When dividing 7260 by 918, we get 7 with a remainder of 834.
The number 7 becomes the next digit in our result. 
Result so far: 14880.6437
Subtracting 6426 from 7260 leaves us with 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

On to step 13:
918 can be fit into 8340 9 times, resulting in a remainder of 78.
Use 9 as the next digit of our solution. 
Result so far: 14880.64379
Deduct 8262 from 8340 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 14:
When dividing 780 by 918, we get 0 with a remainder of 780.
Record the quotient 0 as the next digit in the result. 
Result so far: 14880.64379
Subtracting 0 from 780 leaves us with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Step 15:
If we divide 7800 by 918, we get 8 and a remainder of 456.
The number 8 becomes the next digit in our result. 
Result so far: 14880.6437908
Subtract 7344 from 7800 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.

Moving on to step 16:
When dividing 4560 by 918, we get 4 with a remainder of 888.
The number 4 becomes the next digit in our result. 
Result so far: 14880.64379084
If we subtract 3672 from 4560, we get 888.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8880, and continue the process.

The final outcome is 14880.64379084, with a leftover of 8.88e-07.
