Let's divide 521689 by 98
The aim is to understand the frequency of 98 in 521689.

Step 1:
5 divided by 98 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 98

Let's proceed to step 2:
52 divided by 98 is 0 with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 98

Moving on to step 3:
The number 98 fits into 521 5 times, leaving a remainder of 31.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 490 from 521 leaves us with 31.
Include the next digit (6) from the dividend after 31, then repeat: 316 / 98

Step 4:
316 divided by 98 is 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
Subtract 294 from 316 to get 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 98

On to step 5:
98 can be fit into 228 2 times, resulting in a remainder of 32.
The next digit of our result is 2. 
Result so far: 532.0
If we subtract 196 from 228, we get 32.
Fetch the next digit (9) from the dividend, attach it to 32 and continue: 329 / 98

Moving on to step 6:
The number 98 fits into 329 3 times, leaving a remainder of 35.
The next digit of our result is 3. 
Result so far: 5323.0
The remainder is 35 after subtracting 294 from 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 7:
When dividing 350 by 98, we get 3 with a remainder of 56.
Put 3 as the next digit of the answer. 
Result so far: 5323.3
Subtracting 294 from 350 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 8:
The number 98 fits into 560 5 times, leaving a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 5323.35
Subtract 490 from 560 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
The number 98 fits into 700 7 times, leaving a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 5323.357
If we subtract 686 from 700, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
98 can be fit into 140 1 times, resulting in a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 5323.3571
The remainder is 42 after subtracting 98 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
The number 98 fits into 420 4 times, leaving a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 5323.35714
If we subtract 392 from 420, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
The number 98 fits into 280 2 times, leaving a remainder of 84.
Write down 2 as next digit of the result. 
Result so far: 5323.357142
If we subtract 196 from 280, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 13:
840 divided by 98 is 8 with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 5323.3571428
If we take 784 away from 840, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 14:
98 can be fit into 560 5 times, resulting in a remainder of 70.
The next digit of our result is 5. 
Result so far: 5323.35714285
Subtract 490 from 560 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 5323.35714285, with a leftover of 7e-08.
