306619 ÷ 98 
The aim is to understand the frequency of 98 in 306619.

Step 1:
98 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 98

Let's proceed to step 2:
98 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 98

Advancing to step 3:
98 can be fit into 306 3 times, resulting in a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 12 after subtracting 294 from 306.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 98

On to step 4:
When dividing 126 by 98, we get 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Deduct 98 from 126 and we're left with 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 98

Going ahead to step 5:
If we divide 281 by 98, we get 2 and a remainder of 85.
Put 2 as the next digit of the answer. 
Result so far: 312.0
The remainder is 85 after subtracting 196 from 281.
Take the next digit (9) from the dividend and append it to 85, then repeat: 859 / 98

On to step 6:
When dividing 859 by 98, we get 8 with a remainder of 75.
Record the quotient 8 as the next digit in the result. 
Result so far: 3128.0
Deduct 784 from 859 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 7:
750 divided by 98 is 7 with a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 3128.7
The remainder is 64 after subtracting 686 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 8:
The number 98 fits into 640 6 times, leaving a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 3128.76
The remainder is 52 after subtracting 588 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
The number 98 fits into 520 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 3128.765
The remainder is 30 after subtracting 490 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
If we divide 300 by 98, we get 3 and a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3128.7653
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
If we divide 60 by 98, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 3128.7653
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
98 can be fit into 600 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 3128.765306
If we take 588 away from 600, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
If we divide 120 by 98, we get 1 and a remainder of 22.
The next digit of our result is 1. 
Result so far: 3128.7653061
Subtract 98 from 120 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 14:
When dividing 220 by 98, we get 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 3128.76530612
Deduct 196 from 220 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 3128.76530612 and a remainder of 2.4e-08.
