We look at the division of 601914 by 15 
The aim is to understand the frequency of 15 in 601914.

Advancing to step 1:
15 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 15

On to step 2:
When dividing 60 by 15, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 60 from 60 and we're left with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 15

Moving on to step 3:
The number 15 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 15

Going ahead to step 4:
15 can be fit into 19 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 401.0
The remainder is 4 after subtracting 15 from 19.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 15

Moving on to step 5:
15 can be fit into 41 2 times, resulting in a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 4012.0
If we subtract 30 from 41, we get 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 15

Advancing to step 6:
If we divide 114 by 15, we get 7 and a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 40127.0
If we take 105 away from 114, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
When dividing 90 by 15, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 40127.6
Subtracting 90 from 90 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.

Going ahead to step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 40127.6
If we take 0 away from 0, we end up 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.

Advancing to step 9:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40127.6
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.

In conclusion, the division gives 40127.6 with a balance of 0.0.
