Let's divide 404369 by 15
We want to figure out the number of times 404369 can be divided by 15.

Step 1:
The number 15 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 15

On to step 2:
If we divide 40 by 15, we get 2 and a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 30 from 40 and we're left with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 15

On to step 3:
15 goes into 104 6 times with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we subtract 90 from 104, we get 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 15

Advancing to step 4:
143 divided by 15 is 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 269.0
Deduct 135 from 143 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 15

Advancing to step 5:
15 can be fit into 86 5 times, resulting in a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 2695.0
Subtract 75 from 86 to get 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 15

Let's proceed to step 6:
When dividing 119 by 15, we get 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 26957.0
Deduct 105 from 119 and we're left 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.

Let's proceed to step 7:
When dividing 140 by 15, we get 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 26957.9
If we take 135 away from 140, 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.

Going ahead to step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 26957.93
If we subtract 45 from 50, we 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.

Moving on to step 9:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 26957.933
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.

Our division results in 26957.933 with a remaining 0.0005.
