We divide 507122 by 72
The aim is to understand the frequency of 72 in 507122.

Step 1:
When dividing 5 by 72, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 72

Moving on to step 2:
50 divided by 72 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Grab the next digit (7) from the dividend, add it to 50, then carry on: 507 / 72

Going ahead to step 3:
If we divide 507 by 72, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 504 away from 507, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 72

On to step 4:
72 goes into 31 0 times with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 70.0
The remainder is 31 after subtracting 0 from 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 72

On to step 5:
312 divided by 72 is 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 704.0
The remainder is 24 after subtracting 288 from 312.
Append the next digit (2) from the dividend to 24 and continue with: 242 / 72

Going ahead to step 6:
242 divided by 72 is 3 with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 7043.0
Subtract 216 from 242 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
The number 72 fits into 260 3 times, leaving a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 7043.3
Subtract 216 from 260 to get 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 8:
440 divided by 72 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 7043.36
If we take 432 away from 440, we end up 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.

Let's proceed to step 9:
The number 72 fits into 80 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 7043.361
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
80 divided by 72 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 7043.3611
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.

The quotient of the division is 7043.3611, and the remainder is 8e-05.
