598753 ÷ 15 
The aim is to understand the frequency of 15 in 598753.

Advancing to step 1:
15 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 15

Advancing to step 2:
When dividing 59 by 15, we get 3 with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 14 after subtracting 45 from 59.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 15

Let's proceed to step 3:
15 can be fit into 148 9 times, resulting in a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we take 135 away from 148, we end up with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 15

Let's proceed to step 4:
15 goes into 137 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 399.0
If we take 135 away from 137, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 15

Moving on to step 5:
The number 15 fits into 25 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 3991.0
Subtract 15 from 25 to get 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 15

Advancing to step 6:
15 goes into 103 6 times with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 39916.0
The remainder is 13 after subtracting 90 from 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
The number 15 fits into 130 8 times, leaving a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 39916.8
Deduct 120 from 130 and we're left 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.

Advancing to step 8:
100 divided by 15 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 39916.86
Subtracting 90 from 100 leaves us 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.

Moving on to step 9:
When dividing 100 by 15, we get 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 39916.866
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.

In conclusion, the division gives 39916.866 with a balance of 0.001.
