661992 ÷ 98 
The aim is to understand the frequency of 98 in 661992.

Going ahead to step 1:
The number 98 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 98

Advancing to step 2:
If we divide 66 by 98, we get 0 and a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 98

Advancing to step 3:
If we divide 661 by 98, we get 6 and a remainder of 73.
The next digit of our result is 6. 
Result so far: 6.0
If we take 588 away from 661, we end up with 73.
Include the next digit (9) from the dividend after 73, then repeat: 739 / 98

On to step 4:
If we divide 739 by 98, we get 7 and a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
If we take 686 away from 739, we end up with 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 98

On to step 5:
The number 98 fits into 539 5 times, leaving a remainder of 49.
Use 5 as the next digit of our solution. 
Result so far: 675.0
Subtracting 490 from 539 leaves us with 49.
Append the next digit (2) from the dividend to 49 and continue with: 492 / 98

Advancing to step 6:
98 can be fit into 492 5 times, resulting in a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 6755.0
Subtracting 490 from 492 leaves us 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:
The number 98 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 6755.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
When dividing 200 by 98, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 6755.02
Deduct 196 from 200 and we're left 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:
If we divide 40 by 98, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 6755.02
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.

On to step 10:
400 divided by 98 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 6755.0204
Subtract 392 from 400 to 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:
The number 98 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 6755.0204
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.

Advancing to step 12:
98 can be fit into 800 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 6755.020408
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.

Step 13:
When dividing 160 by 98, we get 1 with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 6755.0204081
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.

Moving on to step 14:
98 can be fit into 620 6 times, resulting in a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 6755.02040816
Subtracting 588 from 620 leaves us 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.

The final outcome is 6755.02040816, with a leftover of 3.2e-08.
