750262 ÷ 15 
The aim is to understand the frequency of 15 in 750262.

Step 1:
7 divided by 15 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 15

On to step 2:
15 can be fit into 75 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 75 from 75 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 15

Advancing to step 3:
When dividing 0 by 15, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 15

Step 4:
15 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 500.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 15

Going ahead to step 5:
If we divide 26 by 15, we get 1 and a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 5001.0
If we take 15 away from 26, we end up with 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 15

Step 6:
If we divide 112 by 15, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 50017.0
Subtract 105 from 112 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
The number 15 fits into 70 4 times, leaving a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 50017.4
If we subtract 60 from 70, 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.

Going ahead to 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: 50017.46
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.

Moving on to step 9:
100 divided by 15 is 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 50017.466
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 50017.466, and the remainder is 0.001.
