We divide 661864 by 98
The aim is to understand the frequency of 98 in 661864.

Step 1:
98 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 98

Step 2:
98 goes into 66 0 times with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 98

Advancing to step 3:
The number 98 fits into 661 6 times, leaving a remainder of 73.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 588 from 661, we get 73.
Fetch the next digit (8) from the dividend, attach it to 73 and continue: 738 / 98

Moving on to step 4:
The number 98 fits into 738 7 times, leaving a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 67.0
The remainder is 52 after subtracting 686 from 738.
Append the next digit (6) from the dividend to 52 and continue with: 526 / 98

Going ahead to step 5:
If we divide 526 by 98, we get 5 and a remainder of 36.
The next digit of our result is 5. 
Result so far: 675.0
If we take 490 away from 526, we end up with 36.
Bring next digit (4) of the dividend behind the 36 and repeat the process: 364 / 98

Let's proceed to step 6:
98 can be fit into 364 3 times, resulting in a remainder of 70.
Write down 3 as next digit of the result. 
Result so far: 6753.0
If we subtract 294 from 364, we 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.

Let's proceed to step 7:
If we divide 700 by 98, we get 7 and a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 6753.7
Subtracting 686 from 700 leaves us with 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 8:
98 goes into 140 1 times with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 6753.71
Subtract 98 from 140 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
When dividing 420 by 98, we get 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 6753.714
The remainder is 28 after subtracting 392 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
98 goes into 280 2 times with a remainder of 84.
Put 2 as the next digit of the answer. 
Result so far: 6753.7142
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.

On to step 11:
The number 98 fits into 840 8 times, leaving a remainder of 56.
The next digit of our result is 8. 
Result so far: 6753.71428
Deduct 784 from 840 and we're left 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.

Step 12:
The number 98 fits into 560 5 times, leaving a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 6753.714285
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.

Let's proceed to step 13:
The number 98 fits into 700 7 times, leaving a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 6753.7142857
Subtracting 686 from 700 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 14:
The number 98 fits into 140 1 times, leaving a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 6753.71428571
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.

The final result is 6753.71428571 with a remainder of 4.2e-08.
