619501 ÷ 15 
The aim is to understand the frequency of 15 in 619501.

Moving on to step 1:
When dividing 6 by 15, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 15

Moving on to step 2:
When dividing 61 by 15, we get 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 60 from 61 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 3:
15 can be fit into 19 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtract 15 from 19 to get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 15

Advancing to step 4:
45 divided by 15 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 413.0
Subtract 45 from 45 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 15

Moving on to step 5:
15 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4130.0
Deduct 0 from 0 and we're left with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 15

Advancing to step 6:
15 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 41300.0
Deduct 0 from 1 and we're left with 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:
When dividing 10 by 15, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 41300.0
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.

On to step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 41300.06
Subtract 90 from 100 to 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.

Advancing to step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 41300.066
Deduct 90 from 100 and we're left 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.

In conclusion, the division gives 41300.066 with a balance of 0.001.
