423196 divided by 15 
Our goal is to divide 423196 by 15.

Step 1:
The number 15 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 15

On to step 2:
When dividing 42 by 15, we get 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 12 after subtracting 30 from 42.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 15

Going ahead to step 3:
The number 15 fits into 123 8 times, leaving a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 3 after subtracting 120 from 123.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 15

Moving on to step 4:
31 divided by 15 is 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 282.0
If we take 30 away from 31, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 15

Moving on to step 5:
The number 15 fits into 19 1 times, leaving a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 2821.0
Subtract 15 from 19 to get 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 15

Let's proceed to step 6:
15 can be fit into 46 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 28213.0
If we subtract 45 from 46, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
If we divide 10 by 15, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 28213.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 15, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 28213.06
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
The next digit of our result is 6. 
Result so far: 28213.066
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 28213.066 with a remaining 0.001.
