18699967 divided by 998 
The aim is to understand the frequency of 998 in 18699967.

Moving on to step 1:
The number 998 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 998

Advancing to step 2:
The number 998 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 998

Let's proceed to step 3:
When dividing 186 by 998, we get 0 with a remainder of 186.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 186 leaves us with 186.
Bring next digit (9) of the dividend behind the 186 and repeat the process: 1869 / 998

On to step 4:
1869 divided by 998 is 1 with a remainder of 871.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 998 from 1869, we get 871.
Include the next digit (9) from the dividend after 871, then repeat: 8719 / 998

On to step 5:
8719 divided by 998 is 8 with a remainder of 735.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 7984 from 8719, we get 735.
Take the next digit (9) from the dividend and append it to 735, then repeat: 7359 / 998

On to step 6:
998 can be fit into 7359 7 times, resulting in a remainder of 373.
Write down 7 as next digit of the result. 
Result so far: 187.0
Subtracting 6986 from 7359 leaves us with 373.
Fetch the next digit (6) from the dividend, attach it to 373 and continue: 3736 / 998

Step 7:
The number 998 fits into 3736 3 times, leaving a remainder of 742.
Record the quotient 3 as the next digit in the result. 
Result so far: 1873.0
If we take 2994 away from 3736, we end up with 742.
Include the next digit (7) from the dividend after 742, then repeat: 7427 / 998

Let's proceed to step 8:
998 goes into 7427 7 times with a remainder of 441.
Put 7 as the next digit of the answer. 
Result so far: 18737.0
If we subtract 6986 from 7427, we get 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Step 9:
998 can be fit into 4410 4 times, resulting in a remainder of 418.
Put 4 as the next digit of the answer. 
Result so far: 18737.4
Subtract 3992 from 4410 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Advancing to step 10:
998 can be fit into 4180 4 times, resulting in a remainder of 188.
The number 4 becomes the next digit in our result. 
Result so far: 18737.44
If we subtract 3992 from 4180, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

The final outcome is 18737.44, with a leftover of 0.188.
