We're dividing 98738667 by 723 
The aim is to understand the frequency of 723 in 98738667.

Advancing to step 1:
9 divided by 723 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 723

Step 2:
When dividing 98 by 723, we get 0 with a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Take the next digit (7) from the dividend and append it to 98, then repeat: 987 / 723

Advancing to step 3:
723 goes into 987 1 times with a remainder of 264.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 723 from 987, we get 264.
Include the next digit (3) from the dividend after 264, then repeat: 2643 / 723

Step 4:
If we divide 2643 by 723, we get 3 and a remainder of 474.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 2169 from 2643, we get 474.
Grab the next digit (8) from the dividend, add it to 474, then carry on: 4748 / 723

Going ahead to step 5:
When dividing 4748 by 723, we get 6 with a remainder of 410.
Use 6 as the next digit of our solution. 
Result so far: 136.0
The remainder is 410 after subtracting 4338 from 4748.
Bring next digit (6) of the dividend behind the 410 and repeat the process: 4106 / 723

Let's proceed to step 6:
If we divide 4106 by 723, we get 5 and a remainder of 491.
The next digit of our result is 5. 
Result so far: 1365.0
Subtracting 3615 from 4106 leaves us with 491.
Include the next digit (6) from the dividend after 491, then repeat: 4916 / 723

Step 7:
If we divide 4916 by 723, we get 6 and a remainder of 578.
The number 6 becomes the next digit in our result. 
Result so far: 13656.0
If we subtract 4338 from 4916, we get 578.
Take the next digit (7) from the dividend and append it to 578, then repeat: 5787 / 723

On to step 8:
723 can be fit into 5787 8 times, resulting in a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 136568.0
If we take 5784 away from 5787, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
723 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 136568.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
300 divided by 723 is 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 136568.0
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The quotient of the division is 136568.0, and the remainder is 0.3.
