980046 ÷ 15 
The aim is to understand the frequency of 15 in 980046.

Going ahead to step 1:
If we divide 9 by 15, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 15

Let's proceed to step 2:
If we divide 98 by 15, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 90 from 98 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 15

Going ahead to step 3:
The number 15 fits into 80 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 65.0
Subtract 75 from 80 to get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 15

Moving on to step 4:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 653.0
If we take 45 away from 50, we end up with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 15

On to step 5:
When dividing 54 by 15, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 6533.0
Deduct 45 from 54 and we're left with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 15

Let's proceed to step 6:
96 divided by 15 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 65336.0
If we take 90 away from 96, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
If we divide 60 by 15, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 65336.4
Subtracting 60 from 60 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 65336.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
15 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 65336.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 65336.4 with a remainder of 0.0.
