721944 ÷ 98 
The aim is to understand the frequency of 98 in 721944.

Let's proceed to step 1:
When dividing 7 by 98, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 98

On to step 2:
If we divide 72 by 98, we get 0 and a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Take the next digit (1) from the dividend and append it to 72, then repeat: 721 / 98

Let's proceed to step 3:
The number 98 fits into 721 7 times, leaving a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 686 from 721, we get 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 98

Let's proceed to step 4:
When dividing 359 by 98, we get 3 with a remainder of 65.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
Subtracting 294 from 359 leaves us with 65.
Take the next digit (4) from the dividend and append it to 65, then repeat: 654 / 98

On to step 5:
The number 98 fits into 654 6 times, leaving a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 736.0
The remainder is 66 after subtracting 588 from 654.
Take the next digit (4) from the dividend and append it to 66, then repeat: 664 / 98

Let's proceed to step 6:
98 can be fit into 664 6 times, resulting in a remainder of 76.
The next digit of our result is 6. 
Result so far: 7366.0
Subtract 588 from 664 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 7:
When dividing 760 by 98, we get 7 with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 7366.7
The remainder is 74 after subtracting 686 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 8:
The number 98 fits into 740 7 times, leaving a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 7366.77
If we subtract 686 from 740, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 7366.77, and the remainder is 0.054.
