We're dividing 905738 by 15 
The aim is to understand the frequency of 15 in 905738.

Advancing to step 1:
15 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 15

Going ahead to step 2:
15 can be fit into 90 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 90 from 90 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 15

On to step 3:
When dividing 5 by 15, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
If we subtract 0 from 5, we get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 15

Step 4:
15 can be fit into 57 3 times, resulting in a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 603.0
If we subtract 45 from 57, we get 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 15

On to step 5:
The number 15 fits into 123 8 times, leaving a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 6038.0
Subtracting 120 from 123 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 15

Advancing to step 6:
15 goes into 38 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 60382.0
The remainder is 8 after subtracting 30 from 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
15 goes into 80 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 60382.5
Deduct 75 from 80 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.

Let's proceed 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: 60382.53
Subtracting 45 from 50 leaves us 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.

Step 9:
When dividing 50 by 15, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 60382.533
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.

The quotient of the division is 60382.533, and the remainder is 0.0005.
