We divide 303717 by 72
The aim is to understand the frequency of 72 in 303717.

Advancing to step 1:
The number 72 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 72

Going ahead to step 2:
The number 72 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 72

Let's proceed to step 3:
When dividing 303 by 72, we get 4 with a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 288 away from 303, we end up with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 72

Step 4:
72 goes into 157 2 times with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 42.0
If we subtract 144 from 157, we get 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 72

Step 5:
When dividing 131 by 72, we get 1 with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 421.0
Subtract 72 from 131 to get 59.
Grab the next digit (7) from the dividend, add it to 59, then carry on: 597 / 72

Advancing to step 6:
The number 72 fits into 597 8 times, leaving a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 4218.0
Deduct 576 from 597 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
210 divided by 72 is 2 with a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 4218.2
Subtract 144 from 210 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 8:
72 goes into 660 9 times with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 4218.29
Deduct 648 from 660 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
72 goes into 120 1 times with a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 4218.291
Subtract 72 from 120 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
When dividing 480 by 72, we get 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 4218.2916
The remainder is 48 after subtracting 432 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
480 divided by 72 is 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 4218.29166
Subtracting 432 from 480 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 4218.29166 and a remainder of 4.8e-05.
