We divide 81475508 by 998
The aim is to understand the frequency of 998 in 81475508.

Going ahead to 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
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 998

Moving on to step 2:
81 divided by 998 is 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (4) from the dividend, add it to 81, then carry on: 814 / 998

Step 3:
If we divide 814 by 998, we get 0 and a remainder of 814.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 814 to get 814.
Grab the next digit (7) from the dividend, add it to 814, then carry on: 8147 / 998

Going ahead to step 4:
If we divide 8147 by 998, we get 8 and a remainder of 163.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 7984 from 8147 and we're left with 163.
Bring next digit (5) of the dividend behind the 163 and repeat the process: 1635 / 998

Advancing to step 5:
If we divide 1635 by 998, we get 1 and a remainder of 637.
Write down 1 as next digit of the result. 
Result so far: 81.0
Subtracting 998 from 1635 leaves us with 637.
Grab the next digit (5) from the dividend, add it to 637, then carry on: 6375 / 998

Advancing to step 6:
The number 998 fits into 6375 6 times, leaving a remainder of 387.
Write down 6 as next digit of the result. 
Result so far: 816.0
If we subtract 5988 from 6375, we get 387.
Take the next digit (0) from the dividend and append it to 387, then repeat: 3870 / 998

Moving on to step 7:
3870 divided by 998 is 3 with a remainder of 876.
The next digit of our result is 3. 
Result so far: 8163.0
The remainder is 876 after subtracting 2994 from 3870.
Grab the next digit (8) from the dividend, add it to 876, then carry on: 8768 / 998

Going ahead to step 8:
998 can be fit into 8768 8 times, resulting in a remainder of 784.
The number 8 becomes the next digit in our result. 
Result so far: 81638.0
If we take 7984 away from 8768, we end up with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Going ahead to step 9:
If we divide 7840 by 998, we get 7 and a remainder of 854.
The number 7 becomes the next digit in our result. 
Result so far: 81638.7
Deduct 6986 from 7840 and we're left with 854.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8540, and continue the process.

Moving on to step 10:
998 can be fit into 8540 8 times, resulting in a remainder of 556.
The next digit of our result is 8. 
Result so far: 81638.78
Subtract 7984 from 8540 to get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Moving on to step 11:
The number 998 fits into 5560 5 times, leaving a remainder of 570.
Put 5 as the next digit of the answer. 
Result so far: 81638.785
If we take 4990 away from 5560, we end up with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

On to step 12:
5700 divided by 998 is 5 with a remainder of 710.
Write down 5 as next digit of the result. 
Result so far: 81638.7855
The remainder is 710 after subtracting 4990 from 5700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

In conclusion, the division gives 81638.7855 with a balance of 0.0071.
