We divide 355702 by 72
The aim is to understand the frequency of 72 in 355702.

Advancing to step 1:
When dividing 3 by 72, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 72

Step 2:
35 divided by 72 is 0 with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Include the next digit (5) from the dividend after 35, then repeat: 355 / 72

Let's proceed to step 3:
72 goes into 355 4 times with a remainder of 67.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 288 from 355 leaves us with 67.
Fetch the next digit (7) from the dividend, attach it to 67 and continue: 677 / 72

Advancing to step 4:
677 divided by 72 is 9 with a remainder of 29.
The next digit of our result is 9. 
Result so far: 49.0
Deduct 648 from 677 and we're left with 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 72

Moving on to step 5:
If we divide 290 by 72, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 494.0
Subtract 288 from 290 to get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 72

Advancing to step 6:
When dividing 22 by 72, we get 0 with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 4940.0
If we take 0 away from 22, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
72 can be fit into 220 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 4940.3
Subtracting 216 from 220 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
If we divide 40 by 72, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4940.3
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
72 can be fit into 400 5 times, resulting in a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 4940.305
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
When dividing 400 by 72, we get 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 4940.3055
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 4940.3055 and a remainder of 0.0004.
