We look at the division of 703181 by 72 
The aim is to understand the frequency of 72 in 703181.

Moving on to step 1:
If we divide 7 by 72, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 72

Advancing to step 2:
When dividing 70 by 72, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Include the next digit (3) from the dividend after 70, then repeat: 703 / 72

Going ahead to step 3:
The number 72 fits into 703 9 times, leaving a remainder of 55.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 648 from 703 and we're left with 55.
Append the next digit (1) from the dividend to 55 and continue with: 551 / 72

Moving on to step 4:
When dividing 551 by 72, we get 7 with a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 97.0
If we take 504 away from 551, we end up with 47.
Include the next digit (8) from the dividend after 47, then repeat: 478 / 72

Advancing to step 5:
When dividing 478 by 72, we get 6 with a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 976.0
The remainder is 46 after subtracting 432 from 478.
Grab the next digit (1) from the dividend, add it to 46, then carry on: 461 / 72

Advancing to step 6:
The number 72 fits into 461 6 times, leaving a remainder of 29.
Write down 6 as next digit of the result. 
Result so far: 9766.0
If we subtract 432 from 461, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
If we divide 290 by 72, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 9766.4
If we subtract 288 from 290, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
20 divided by 72 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 9766.4
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
The number 72 fits into 200 2 times, leaving a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 9766.402
If we subtract 144 from 200, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
The number 72 fits into 560 7 times, leaving a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 9766.4027
Subtract 504 from 560 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
560 divided by 72 is 7 with a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 9766.40277
Subtract 504 from 560 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 9766.40277 with a remainder of 5.6e-05.
