686488 divided by 98 
The aim is to understand the frequency of 98 in 686488.

Let's proceed to step 1:
98 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 98

Moving on to step 2:
98 can be fit into 68 0 times, resulting in a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 98

On to step 3:
686 divided by 98 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 686 from 686, we get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 98

Let's proceed to step 4:
98 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 70.0
Subtract 0 from 4 to get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 98

Moving on to step 5:
When dividing 48 by 98, we get 0 with a remainder of 48.
The next digit of our result is 0. 
Result so far: 700.0
If we subtract 0 from 48, we get 48.
Take the next digit (8) from the dividend and append it to 48, then repeat: 488 / 98

On to step 6:
If we divide 488 by 98, we get 4 and a remainder of 96.
Use 4 as the next digit of our solution. 
Result so far: 7004.0
If we subtract 392 from 488, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 7:
960 divided by 98 is 9 with a remainder of 78.
The number 9 becomes the next digit in our result. 
Result so far: 7004.9
The remainder is 78 after subtracting 882 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 8:
When dividing 780 by 98, we get 7 with a remainder of 94.
Record the quotient 7 as the next digit in the result. 
Result so far: 7004.97
Subtracting 686 from 780 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 9:
The number 98 fits into 940 9 times, leaving a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 7004.979
Subtract 882 from 940 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 10:
The number 98 fits into 580 5 times, leaving a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 7004.9795
If we take 490 away from 580, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 11:
98 can be fit into 900 9 times, resulting in a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 7004.97959
Subtract 882 from 900 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
180 divided by 98 is 1 with a remainder of 82.
Record the quotient 1 as the next digit in the result. 
Result so far: 7004.979591
The remainder is 82 after subtracting 98 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 13:
820 divided by 98 is 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 7004.9795918
Subtract 784 from 820 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 14:
98 goes into 360 3 times with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 7004.97959183
If we subtract 294 from 360, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

After the division, we end up with 7004.97959183 and a remainder of 6.6e-08.
