We divide 697958 by 15
The aim is to understand the frequency of 15 in 697958.

On to step 1:
If we divide 6 by 15, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 15

Step 2:
The number 15 fits into 69 4 times, leaving a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 60 from 69 to get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 15

Advancing to step 3:
When dividing 97 by 15, we get 6 with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we take 90 away from 97, we end up with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 15

Step 4:
15 goes into 79 5 times with a remainder of 4.
The next digit of our result is 5. 
Result so far: 465.0
The remainder is 4 after subtracting 75 from 79.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 15

Step 5:
The number 15 fits into 45 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 4653.0
If we subtract 45 from 45, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 15

Advancing to step 6:
15 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 46530.0
Deduct 0 from 8 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
If we divide 80 by 15, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 46530.5
If we take 75 away from 80, we end up 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:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 46530.53
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.

On to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 46530.533
Subtract 45 from 50 to 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.

In conclusion, the division gives 46530.533 with a balance of 0.0005.
