93975545 divided by 15 
The aim is to understand the frequency of 15 in 93975545.

Advancing to step 1:
The number 15 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 15

On to step 2:
15 can be fit into 93 6 times, resulting in a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 90 away from 93, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 15

Moving on to step 3:
15 goes into 39 2 times with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 62.0
If we subtract 30 from 39, we get 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 15

Step 4:
When dividing 97 by 15, we get 6 with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 626.0
The remainder is 7 after subtracting 90 from 97.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 15

On to step 5:
15 can be fit into 75 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 6265.0
Subtract 75 from 75 to get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 15

Advancing to step 6:
When dividing 5 by 15, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 62650.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 15

Going ahead to step 7:
54 divided by 15 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 626503.0
Deduct 45 from 54 and we're left with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 15

On to step 8:
95 divided by 15 is 6 with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 6265036.0
Deduct 90 from 95 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.

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: 6265036.3
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.

Going ahead to step 10:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 6265036.33
If we take 45 away from 50, 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.

In conclusion, the division gives 6265036.33 with a balance of 0.005.
