We're dividing 72343488 by 726 
The aim is to understand the frequency of 726 in 72343488.

Going ahead to step 1:
The number 726 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 726

On to step 2:
The number 726 fits into 72 0 times, leaving a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Append the next digit (3) from the dividend to 72 and continue with: 723 / 726

On to step 3:
723 divided by 726 is 0 with a remainder of 723.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 723 to get 723.
Include the next digit (4) from the dividend after 723, then repeat: 7234 / 726

Advancing to step 4:
7234 divided by 726 is 9 with a remainder of 700.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 6534 from 7234, we get 700.
Bring next digit (3) of the dividend behind the 700 and repeat the process: 7003 / 726

Going ahead to step 5:
When dividing 7003 by 726, we get 9 with a remainder of 469.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
If we take 6534 away from 7003, we end up with 469.
Append the next digit (4) from the dividend to 469 and continue with: 4694 / 726

On to step 6:
726 goes into 4694 6 times with a remainder of 338.
The number 6 becomes the next digit in our result. 
Result so far: 996.0
Deduct 4356 from 4694 and we're left with 338.
Grab the next digit (8) from the dividend, add it to 338, then carry on: 3388 / 726

Going ahead to step 7:
The number 726 fits into 3388 4 times, leaving a remainder of 484.
The number 4 becomes the next digit in our result. 
Result so far: 9964.0
Subtract 2904 from 3388 to get 484.
Grab the next digit (8) from the dividend, add it to 484, then carry on: 4848 / 726

Step 8:
If we divide 4848 by 726, we get 6 and a remainder of 492.
The number 6 becomes the next digit in our result. 
Result so far: 99646.0
If we take 4356 away from 4848, we end up with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Step 9:
726 goes into 4920 6 times with a remainder of 564.
Put 6 as the next digit of the answer. 
Result so far: 99646.6
If we take 4356 away from 4920, we end up with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Let's proceed to step 10:
726 can be fit into 5640 7 times, resulting in a remainder of 558.
Write down 7 as next digit of the result. 
Result so far: 99646.67
Subtract 5082 from 5640 to get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

On to step 11:
When dividing 5580 by 726, we get 7 with a remainder of 498.
Use 7 as the next digit of our solution. 
Result so far: 99646.677
Deduct 5082 from 5580 and we're left with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

After the division, we end up with 99646.677 and a remainder of 0.0498.
