Let's divide 86514011 by 998
The aim is to understand the frequency of 998 in 86514011.

Advancing to step 1:
The number 998 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 998

Step 2:
998 goes into 86 0 times with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Append the next digit (5) from the dividend to 86 and continue with: 865 / 998

Moving on to step 3:
865 divided by 998 is 0 with a remainder of 865.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 865 after subtracting 0 from 865.
Fetch the next digit (1) from the dividend, attach it to 865 and continue: 8651 / 998

Going ahead to step 4:
If we divide 8651 by 998, we get 8 and a remainder of 667.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 7984 from 8651 leaves us with 667.
Grab the next digit (4) from the dividend, add it to 667, then carry on: 6674 / 998

Moving on to step 5:
If we divide 6674 by 998, we get 6 and a remainder of 686.
Write down 6 as next digit of the result. 
Result so far: 86.0
If we take 5988 away from 6674, we end up with 686.
Grab the next digit (0) from the dividend, add it to 686, then carry on: 6860 / 998

On to step 6:
6860 divided by 998 is 6 with a remainder of 872.
The number 6 becomes the next digit in our result. 
Result so far: 866.0
Deduct 5988 from 6860 and we're left with 872.
Include the next digit (1) from the dividend after 872, then repeat: 8721 / 998

Step 7:
998 can be fit into 8721 8 times, resulting in a remainder of 737.
Write down 8 as next digit of the result. 
Result so far: 8668.0
The remainder is 737 after subtracting 7984 from 8721.
Grab the next digit (1) from the dividend, add it to 737, then carry on: 7371 / 998

Advancing to step 8:
When dividing 7371 by 998, we get 7 with a remainder of 385.
Record the quotient 7 as the next digit in the result. 
Result so far: 86687.0
Subtracting 6986 from 7371 leaves us with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Going ahead to step 9:
3850 divided by 998 is 3 with a remainder of 856.
Use 3 as the next digit of our solution. 
Result so far: 86687.3
If we take 2994 away from 3850, we end up with 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Advancing to step 10:
8560 divided by 998 is 8 with a remainder of 576.
The number 8 becomes the next digit in our result. 
Result so far: 86687.38
The remainder is 576 after subtracting 7984 from 8560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 11:
998 can be fit into 5760 5 times, resulting in a remainder of 770.
Use 5 as the next digit of our solution. 
Result so far: 86687.385
Deduct 4990 from 5760 and we're left with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Moving on to step 12:
7700 divided by 998 is 7 with a remainder of 714.
Use 7 as the next digit of our solution. 
Result so far: 86687.3857
Subtract 6986 from 7700 to get 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

Step 13:
When dividing 7140 by 998, we get 7 with a remainder of 154.
The number 7 becomes the next digit in our result. 
Result so far: 86687.38577
The remainder is 154 after subtracting 6986 from 7140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

After the division, we end up with 86687.38577 and a remainder of 0.000154.
