420100 ÷ 98 
The aim is to understand the frequency of 98 in 420100.

Advancing to step 1:
98 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 98

Advancing to step 2:
42 divided by 98 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 98

On to step 3:
If we divide 420 by 98, we get 4 and a remainder of 28.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 392 from 420 and we're left with 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 98

Step 4:
98 can be fit into 281 2 times, resulting in a remainder of 85.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
If we subtract 196 from 281, we get 85.
Bring next digit (0) of the dividend behind the 85 and repeat the process: 850 / 98

Moving on to step 5:
The number 98 fits into 850 8 times, leaving a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 428.0
If we take 784 away from 850, we end up with 66.
Grab the next digit (0) from the dividend, add it to 66, then carry on: 660 / 98

Going ahead to step 6:
When dividing 660 by 98, we get 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 4286.0
Subtracting 588 from 660 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 7:
If we divide 720 by 98, we get 7 and a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 4286.7
Deduct 686 from 720 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
When dividing 340 by 98, we get 3 with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 4286.73
The remainder is 46 after subtracting 294 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
98 goes into 460 4 times with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 4286.734
Subtract 392 from 460 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 10:
The number 98 fits into 680 6 times, leaving a remainder of 92.
Put 6 as the next digit of the answer. 
Result so far: 4286.7346
Subtract 588 from 680 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 11:
98 goes into 920 9 times with a remainder of 38.
The next digit of our result is 9. 
Result so far: 4286.73469
The remainder is 38 after subtracting 882 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
The number 98 fits into 380 3 times, leaving a remainder of 86.
Record the quotient 3 as the next digit in the result. 
Result so far: 4286.734693
If we take 294 away from 380, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 13:
860 divided by 98 is 8 with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 4286.7346938
Subtract 784 from 860 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 14:
The number 98 fits into 760 7 times, leaving a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 4286.73469387
Deduct 686 from 760 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final outcome is 4286.73469387, with a leftover of 7.4e-08.
