784394 ÷ 98 
The aim is to understand the frequency of 98 in 784394.

Advancing to step 1:
When dividing 7 by 98, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 98

Going ahead to step 2:
When dividing 78 by 98, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Grab the next digit (4) from the dividend, add it to 78, then carry on: 784 / 98

Let's proceed to step 3:
The number 98 fits into 784 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 784 from 784 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 98

Going ahead to step 4:
3 divided by 98 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
If we take 0 away from 3, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 98

Moving on to step 5:
98 can be fit into 39 0 times, resulting in a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 800.0
Subtracting 0 from 39 leaves us with 39.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 98

Going ahead to step 6:
394 divided by 98 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 8004.0
If we take 392 away from 394, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
98 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 8004.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
200 divided by 98 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 8004.02
Subtracting 196 from 200 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
98 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 8004.02
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
When dividing 400 by 98, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 8004.0204
If we subtract 392 from 400, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
When dividing 80 by 98, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 8004.0204
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
The number 98 fits into 800 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 8004.020408
Subtract 784 from 800 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
160 divided by 98 is 1 with a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 8004.0204081
If we take 98 away from 160, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 14:
The number 98 fits into 620 6 times, leaving a remainder of 32.
The next digit of our result is 6. 
Result so far: 8004.02040816
If we take 588 away from 620, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 8004.02040816 with a remaining 3.2e-08.
