We divide 879485 by 72
The aim is to understand the frequency of 72 in 879485.

On to step 1:
The number 72 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 72

Moving on to step 2:
72 goes into 87 1 times with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 72 from 87 to get 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 72

Advancing to step 3:
The number 72 fits into 159 2 times, leaving a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 144 from 159 to get 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 72

Advancing to step 4:
The number 72 fits into 154 2 times, leaving a remainder of 10.
The next digit of our result is 2. 
Result so far: 122.0
Subtract 144 from 154 to get 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 72

Step 5:
72 goes into 108 1 times with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 1221.0
If we subtract 72 from 108, we get 36.
Fetch the next digit (5) from the dividend, attach it to 36 and continue: 365 / 72

Moving on to step 6:
When dividing 365 by 72, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 12215.0
The remainder is 5 after subtracting 360 from 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
72 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 12215.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
72 goes into 500 6 times with a remainder of 68.
Write down 6 as next digit of the result. 
Result so far: 12215.06
The remainder is 68 after subtracting 432 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 9:
72 goes into 680 9 times with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 12215.069
If we take 648 away from 680, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
The number 72 fits into 320 4 times, leaving a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 12215.0694
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
320 divided by 72 is 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 12215.06944
Deduct 288 from 320 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 12215.06944 and a remainder of 3.2e-05.
