349570 divided by 72 
The aim is to understand the frequency of 72 in 349570.

Advancing to step 1:
3 divided by 72 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 72

Advancing to step 2:
34 divided by 72 is 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Take the next digit (9) from the dividend and append it to 34, then repeat: 349 / 72

Moving on to step 3:
When dividing 349 by 72, we get 4 with a remainder of 61.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 288 away from 349, we end up with 61.
Take the next digit (5) from the dividend and append it to 61, then repeat: 615 / 72

On to step 4:
72 goes into 615 8 times with a remainder of 39.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtracting 576 from 615 leaves us with 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 72

Advancing to step 5:
72 goes into 397 5 times with a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 485.0
Deduct 360 from 397 and we're left with 37.
Fetch the next digit (0) from the dividend, attach it to 37 and continue: 370 / 72

Going ahead to step 6:
If we divide 370 by 72, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 4855.0
The remainder is 10 after subtracting 360 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
The number 72 fits into 100 1 times, leaving a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 4855.1
If we subtract 72 from 100, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
72 goes into 280 3 times with a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 4855.13
Deduct 216 from 280 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
When dividing 640 by 72, we get 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 4855.138
Subtracting 576 from 640 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
The number 72 fits into 640 8 times, leaving a remainder of 64.
The next digit of our result is 8. 
Result so far: 4855.1388
The remainder is 64 after subtracting 576 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 4855.1388 with a balance of 0.00064.
