We're dividing 407498 by 72 
The aim is to understand the frequency of 72 in 407498.

Step 1:
4 divided by 72 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 72

Let's proceed to step 2:
The number 72 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Append the next digit (7) from the dividend to 40 and continue with: 407 / 72

Going ahead to step 3:
When dividing 407 by 72, we get 5 with a remainder of 47.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 360 from 407 to get 47.
Grab the next digit (4) from the dividend, add it to 47, then carry on: 474 / 72

On to step 4:
When dividing 474 by 72, we get 6 with a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
If we take 432 away from 474, we end up with 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 72

Step 5:
429 divided by 72 is 5 with a remainder of 69.
The next digit of our result is 5. 
Result so far: 565.0
If we take 360 away from 429, we end up with 69.
Grab the next digit (8) from the dividend, add it to 69, then carry on: 698 / 72

Let's proceed to step 6:
698 divided by 72 is 9 with a remainder of 50.
The number 9 becomes the next digit in our result. 
Result so far: 5659.0
Subtracting 648 from 698 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
When dividing 500 by 72, we get 6 with a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 5659.6
Subtract 432 from 500 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 8:
72 goes into 680 9 times with a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 5659.69
If we subtract 648 from 680, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
320 divided by 72 is 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 5659.694
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
If we divide 320 by 72, we get 4 and a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 5659.6944
Subtracting 288 from 320 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 5659.6944 and a remainder of 0.00032.
