761461 divided by 15 
The aim is to understand the frequency of 15 in 761461.

Advancing to step 1:
When dividing 7 by 15, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 15

Let's proceed to step 2:
76 divided by 15 is 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 1 after subtracting 75 from 76.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 15

Let's proceed to step 3:
15 can be fit into 11 0 times, resulting in a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtract 0 from 11 to get 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 15

Going ahead to step 4:
15 goes into 114 7 times with a remainder of 9.
The next digit of our result is 7. 
Result so far: 507.0
Subtract 105 from 114 to get 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 15

Moving on to step 5:
When dividing 96 by 15, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 5076.0
If we take 90 away from 96, we end up with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 15

Let's proceed to step 6:
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: 50764.0
Deduct 60 from 61 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.

Step 7:
15 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 50764.0
Subtracting 0 from 10 leaves us 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.

Advancing to step 8:
15 goes into 100 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 50764.06
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:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 50764.066
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.

The final result is 50764.066 with a remainder of 0.001.
