408018 ÷ 98 
The aim is to understand the frequency of 98 in 408018.

Step 1:
98 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 98

Going ahead to step 2:
98 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 98

On to step 3:
When dividing 408 by 98, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 392 from 408, we get 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 98

Advancing to step 4:
160 divided by 98 is 1 with a remainder of 62.
The next digit of our result is 1. 
Result so far: 41.0
If we take 98 away from 160, we end up with 62.
Bring next digit (1) of the dividend behind the 62 and repeat the process: 621 / 98

Advancing to step 5:
621 divided by 98 is 6 with a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 416.0
Subtracting 588 from 621 leaves us with 33.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 98

Step 6:
If we divide 338 by 98, we get 3 and a remainder of 44.
The next digit of our result is 3. 
Result so far: 4163.0
The remainder is 44 after subtracting 294 from 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
98 goes into 440 4 times with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 4163.4
Deduct 392 from 440 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 8:
When dividing 480 by 98, we get 4 with a remainder of 88.
The next digit of our result is 4. 
Result so far: 4163.44
Deduct 392 from 480 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

After the division, we end up with 4163.44 and a remainder of 0.088.
