We're dividing 86456927 by 998 
The aim is to understand the frequency of 998 in 86456927.

Step 1:
8 divided by 998 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 998

On to step 2:
998 can be fit into 86 0 times, resulting in a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Bring next digit (4) of the dividend behind the 86 and repeat the process: 864 / 998

Moving on to step 3:
The number 998 fits into 864 0 times, leaving a remainder of 864.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 864 to get 864.
Fetch the next digit (5) from the dividend, attach it to 864 and continue: 8645 / 998

Let's proceed to step 4:
8645 divided by 998 is 8 with a remainder of 661.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 7984 from 8645, we get 661.
Take the next digit (6) from the dividend and append it to 661, then repeat: 6616 / 998

Step 5:
998 can be fit into 6616 6 times, resulting in a remainder of 628.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Subtract 5988 from 6616 to get 628.
Append the next digit (9) from the dividend to 628 and continue with: 6289 / 998

Step 6:
The number 998 fits into 6289 6 times, leaving a remainder of 301.
Write down 6 as next digit of the result. 
Result so far: 866.0
If we take 5988 away from 6289, we end up with 301.
Bring next digit (2) of the dividend behind the 301 and repeat the process: 3012 / 998

Step 7:
When dividing 3012 by 998, we get 3 with a remainder of 18.
The next digit of our result is 3. 
Result so far: 8663.0
If we subtract 2994 from 3012, we get 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 998

Moving on to step 8:
998 can be fit into 187 0 times, resulting in a remainder of 187.
Record the quotient 0 as the next digit in the result. 
Result so far: 86630.0
The remainder is 187 after subtracting 0 from 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Advancing to step 9:
The number 998 fits into 1870 1 times, leaving a remainder of 872.
Put 1 as the next digit of the answer. 
Result so far: 86630.1
If we take 998 away from 1870, we end up with 872.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8720, and continue the process.

Let's proceed to step 10:
When dividing 8720 by 998, we get 8 with a remainder of 736.
The next digit of our result is 8. 
Result so far: 86630.18
The remainder is 736 after subtracting 7984 from 8720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Moving on to step 11:
The number 998 fits into 7360 7 times, leaving a remainder of 374.
Put 7 as the next digit of the answer. 
Result so far: 86630.187
Subtract 6986 from 7360 to get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Let's proceed to step 12:
The number 998 fits into 3740 3 times, leaving a remainder of 746.
The number 3 becomes the next digit in our result. 
Result so far: 86630.1873
Subtract 2994 from 3740 to get 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Going ahead to step 13:
The number 998 fits into 7460 7 times, leaving a remainder of 474.
Use 7 as the next digit of our solution. 
Result so far: 86630.18737
Deduct 6986 from 7460 and we're left with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

On to step 14:
4740 divided by 998 is 4 with a remainder of 748.
Write down 4 as next digit of the result. 
Result so far: 86630.187374
If we take 3992 away from 4740, we end up with 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Going ahead to step 15:
The number 998 fits into 7480 7 times, leaving a remainder of 494.
The next digit of our result is 7. 
Result so far: 86630.1873747
If we take 6986 away from 7480, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Moving on to step 16:
998 goes into 4940 4 times with a remainder of 948.
The next digit of our result is 4. 
Result so far: 86630.18737474
If we subtract 3992 from 4940, we get 948.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9480, and continue the process.

The final result is 86630.18737474 with a remainder of 9.48e-07.
