251252 divided by 72 
The aim is to understand the frequency of 72 in 251252.

Step 1:
The number 72 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 72

Moving on to step 2:
25 divided by 72 is 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 72

Moving on to step 3:
When dividing 251 by 72, we get 3 with a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 35 after subtracting 216 from 251.
Take the next digit (2) from the dividend and append it to 35, then repeat: 352 / 72

Moving on to step 4:
If we divide 352 by 72, we get 4 and a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Deduct 288 from 352 and we're left with 64.
Append the next digit (5) from the dividend to 64 and continue with: 645 / 72

Step 5:
72 can be fit into 645 8 times, resulting in a remainder of 69.
Use 8 as the next digit of our solution. 
Result so far: 348.0
Subtracting 576 from 645 leaves us with 69.
Grab the next digit (2) from the dividend, add it to 69, then carry on: 692 / 72

Step 6:
72 can be fit into 692 9 times, resulting in a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 3489.0
Deduct 648 from 692 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
72 goes into 440 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 3489.6
Subtracting 432 from 440 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
The number 72 fits into 80 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 3489.61
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
If we divide 80 by 72, we get 1 and a remainder of 8.
The next digit of our result is 1. 
Result so far: 3489.611
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 3489.611 with a balance of 0.0008.
