We divide 315099 by 72
The aim is to understand the frequency of 72 in 315099.

Going ahead to step 1:
72 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 72

Let's proceed to step 2:
If we divide 31 by 72, we get 0 and a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 72

On to step 3:
If we divide 315 by 72, we get 4 and a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 288 from 315 and we're left with 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 72

Step 4:
When dividing 270 by 72, we get 3 with a remainder of 54.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
The remainder is 54 after subtracting 216 from 270.
Grab the next digit (9) from the dividend, add it to 54, then carry on: 549 / 72

On to step 5:
The number 72 fits into 549 7 times, leaving a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 437.0
If we subtract 504 from 549, we get 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 72

On to step 6:
459 divided by 72 is 6 with a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 4376.0
Subtract 432 from 459 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
72 goes into 270 3 times with a remainder of 54.
Use 3 as the next digit of our solution. 
Result so far: 4376.3
If we take 216 away from 270, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 8:
When dividing 540 by 72, we get 7 with a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 4376.37
Subtract 504 from 540 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
72 goes into 360 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4376.375
If we subtract 360 from 360, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
0 divided by 72 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4376.375
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
72 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4376.375
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 4376.375 with a remainder of 0.0.
