Let's divide 18169965 by 15
We're looking to find how many times 15 goes into 18169965.

Going ahead to step 1:
15 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 15

Step 2:
15 can be fit into 18 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we take 15 away from 18, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 15

Let's proceed to step 3:
When dividing 31 by 15, we get 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 30 from 31 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 15

Moving on to step 4:
15 can be fit into 16 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 121.0
If we take 15 away from 16, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 15

Advancing to step 5:
19 divided by 15 is 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1211.0
Subtract 15 from 19 to get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 15

Let's proceed to step 6:
When dividing 49 by 15, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 12113.0
The remainder is 4 after subtracting 45 from 49.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 15

Moving on to step 7:
15 can be fit into 46 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 121133.0
If we take 45 away from 46, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 15

Moving on to step 8:
15 goes into 15 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1211331.0
If we take 15 away from 15, 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.

Advancing to step 9:
15 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1211331.0
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.

Step 10:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1211331.0
Subtract 0 from 0 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.

The quotient of the division is 1211331.0, and the remainder is 0.0.
