524130 divided by 72 
The aim is to understand the frequency of 72 in 524130.

Step 1:
72 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 72

On to step 2:
The number 72 fits into 52 0 times, leaving a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Append the next digit (4) from the dividend to 52 and continue with: 524 / 72

Step 3:
When dividing 524 by 72, we get 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 504 from 524 and we're left with 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 72

Step 4:
72 can be fit into 201 2 times, resulting in a remainder of 57.
The next digit of our result is 2. 
Result so far: 72.0
If we take 144 away from 201, we end up with 57.
Take the next digit (3) from the dividend and append it to 57, then repeat: 573 / 72

Moving on to step 5:
If we divide 573 by 72, we get 7 and a remainder of 69.
Use 7 as the next digit of our solution. 
Result so far: 727.0
If we subtract 504 from 573, we get 69.
Append the next digit (0) from the dividend to 69 and continue with: 690 / 72

Advancing to step 6:
72 can be fit into 690 9 times, resulting in a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 7279.0
Subtracting 648 from 690 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
The number 72 fits into 420 5 times, leaving a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 7279.5
If we take 360 away from 420, we end up 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.

On to step 8:
When dividing 600 by 72, we get 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 7279.58
The remainder is 24 after subtracting 576 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
72 can be fit into 240 3 times, resulting in a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 7279.583
If we take 216 away from 240, we end up 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.

Advancing to step 10:
If we divide 240 by 72, we get 3 and a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 7279.5833
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 7279.5833 with a remainder of 0.00024.
