898881 ÷ 15 
The aim is to understand the frequency of 15 in 898881.

Let's proceed to step 1:
15 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 15

Step 2:
When dividing 89 by 15, we get 5 with a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 75 from 89, we get 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 15

Moving on to step 3:
148 divided by 15 is 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
The remainder is 13 after subtracting 135 from 148.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 15

On to step 4:
15 can be fit into 138 9 times, resulting in a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 599.0
If we subtract 135 from 138, we get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 15

Moving on to step 5:
If we divide 38 by 15, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 5992.0
Deduct 30 from 38 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 15

Moving on to step 6:
15 goes into 81 5 times with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 59925.0
Subtract 75 from 81 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
The number 15 fits into 60 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 59925.4
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
15 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 59925.4
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.

On to step 9:
0 divided by 15 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 59925.4
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.

Our division results in 59925.4 with a remaining 0.0.
