We look at the division of 69170999 by 15 
Our goal is to divide 69170999 by 15.

Let's proceed to step 1:
15 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 15

Advancing to step 2:
When dividing 69 by 15, we get 4 with a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 60 away from 69, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 15

Moving on to step 3:
The number 15 fits into 91 6 times, leaving a remainder of 1.
The next digit of our result is 6. 
Result so far: 46.0
The remainder is 1 after subtracting 90 from 91.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 15

Moving on to step 4:
When dividing 17 by 15, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 461.0
The remainder is 2 after subtracting 15 from 17.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 15

Moving on to step 5:
15 can be fit into 20 1 times, resulting in a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 4611.0
Subtracting 15 from 20 leaves us with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 15

Let's proceed to step 6:
15 can be fit into 59 3 times, resulting in a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 46113.0
Deduct 45 from 59 and we're left with 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 15

On to step 7:
The number 15 fits into 149 9 times, leaving a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 461139.0
Subtract 135 from 149 to get 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 15

Step 8:
If we divide 149 by 15, we get 9 and a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 4611399.0
If we take 135 away from 149, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
The number 15 fits into 140 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 4611399.9
Subtracting 135 from 140 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 4611399.93
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
When dividing 50 by 15, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 4611399.933
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 4611399.933, and the remainder is 0.0005.
