Let's divide 20419610 by 15
We want to divide 20419610 by 15.

Advancing to step 1:
15 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 15

On to step 2:
15 can be fit into 20 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 15 away from 20, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 15

Step 3:
When dividing 54 by 15, we get 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 45 from 54, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 15

Moving on to step 4:
When dividing 91 by 15, we get 6 with a remainder of 1.
The next digit of our result is 6. 
Result so far: 136.0
Subtracting 90 from 91 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 15

Going ahead 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: 1361.0
Subtract 15 from 19 to get 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 15

On to step 6:
46 divided by 15 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 13613.0
The remainder is 1 after subtracting 45 from 46.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 15

Moving on to step 7:
11 divided by 15 is 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 136130.0
The remainder is 11 after subtracting 0 from 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 15

Let's proceed to step 8:
The number 15 fits into 110 7 times, leaving a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 1361307.0
Subtract 105 from 110 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.

Going ahead to step 9:
When dividing 50 by 15, we get 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 1361307.3
Deduct 45 from 50 and we're left 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:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 1361307.33
Deduct 45 from 50 and we're left 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 final outcome is 1361307.33, with a leftover of 0.005.
