We're dividing 13660591 by 415 
We want to figure out the number of times 13660591 can be divided by 415.

Moving on to step 1:
When dividing 1 by 415, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 415

Let's proceed to step 2:
415 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
Deduct 0 from 13 and we're left with 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 415

On to step 3:
415 can be fit into 136 0 times, resulting in a remainder of 136.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 136, we get 136.
Fetch the next digit (6) from the dividend, attach it to 136 and continue: 1366 / 415

Going ahead to step 4:
415 goes into 1366 3 times with a remainder of 121.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 1245 from 1366 to get 121.
Grab the next digit (0) from the dividend, add it to 121, then carry on: 1210 / 415

Moving on to step 5:
415 can be fit into 1210 2 times, resulting in a remainder of 380.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Subtract 830 from 1210 to get 380.
Append the next digit (5) from the dividend to 380 and continue with: 3805 / 415

Step 6:
The number 415 fits into 3805 9 times, leaving a remainder of 70.
Write down 9 as next digit of the result. 
Result so far: 329.0
Deduct 3735 from 3805 and we're left with 70.
Take the next digit (9) from the dividend and append it to 70, then repeat: 709 / 415

Step 7:
709 divided by 415 is 1 with a remainder of 294.
The number 1 becomes the next digit in our result. 
Result so far: 3291.0
Subtracting 415 from 709 leaves us with 294.
Fetch the next digit (1) from the dividend, attach it to 294 and continue: 2941 / 415

Let's proceed to step 8:
When dividing 2941 by 415, we get 7 with a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 32917.0
The remainder is 36 after subtracting 2905 from 2941.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
415 goes into 360 0 times with a remainder of 360.
Put 0 as the next digit of the answer. 
Result so far: 32917.0
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 10:
The number 415 fits into 3600 8 times, leaving a remainder of 280.
Record the quotient 8 as the next digit in the result. 
Result so far: 32917.08
Subtract 3320 from 3600 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 11:
When dividing 2800 by 415, we get 6 with a remainder of 310.
The number 6 becomes the next digit in our result. 
Result so far: 32917.086
The remainder is 310 after subtracting 2490 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 12:
415 can be fit into 3100 7 times, resulting in a remainder of 195.
Write down 7 as next digit of the result. 
Result so far: 32917.0867
Deduct 2905 from 3100 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 13:
1950 divided by 415 is 4 with a remainder of 290.
Put 4 as the next digit of the answer. 
Result so far: 32917.08674
If we subtract 1660 from 1950, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 14:
If we divide 2900 by 415, we get 6 and a remainder of 410.
The next digit of our result is 6. 
Result so far: 32917.086746
Subtract 2490 from 2900 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 15:
4100 divided by 415 is 9 with a remainder of 365.
Put 9 as the next digit of the answer. 
Result so far: 32917.0867469
Deduct 3735 from 4100 and we're left with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Moving on to step 16:
The number 415 fits into 3650 8 times, leaving a remainder of 330.
Put 8 as the next digit of the answer. 
Result so far: 32917.08674698
Subtract 3320 from 3650 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

The final result is 32917.08674698 with a remainder of 3.3e-07.
