Let's divide 906961 by 15
The aim is to understand the frequency of 15 in 906961.

Going ahead to step 1:
If we divide 9 by 15, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 15

Step 2:
If we divide 90 by 15, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 90 from 90 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 15

Advancing to step 3:
When dividing 6 by 15, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
If we take 0 away from 6, we end up with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 15

Step 4:
When dividing 69 by 15, we get 4 with a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 604.0
If we take 60 away from 69, we end up with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 15

Moving on to step 5:
15 goes into 96 6 times with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 6046.0
If we take 90 away from 96, we end up with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 15

On to step 6:
When dividing 61 by 15, we get 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 60464.0
If we subtract 60 from 61, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
When dividing 10 by 15, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 60464.0
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:
When dividing 100 by 15, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 60464.06
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.

Going ahead to step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 60464.066
If we take 90 away from 100, we end up 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.

Our division results in 60464.066 with a remaining 0.001.
