We divide 649975 by 72
The aim is to understand the frequency of 72 in 649975.

On to step 1:
72 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 72

Advancing to step 2:
72 goes into 64 0 times with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Append the next digit (9) from the dividend to 64 and continue with: 649 / 72

Let's proceed to step 3:
The number 72 fits into 649 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 648 from 649 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 72

Let's proceed to step 4:
72 can be fit into 19 0 times, resulting in a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 90.0
Subtract 0 from 19 to get 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 72

Let's proceed to step 5:
If we divide 197 by 72, we get 2 and a remainder of 53.
Put 2 as the next digit of the answer. 
Result so far: 902.0
The remainder is 53 after subtracting 144 from 197.
Bring next digit (5) of the dividend behind the 53 and repeat the process: 535 / 72

Moving on to step 6:
72 can be fit into 535 7 times, resulting in a remainder of 31.
The next digit of our result is 7. 
Result so far: 9027.0
If we subtract 504 from 535, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
If we divide 310 by 72, we get 4 and a remainder of 22.
The next digit of our result is 4. 
Result so far: 9027.4
The remainder is 22 after subtracting 288 from 310.
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 8:
72 goes into 220 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 9027.43
If we subtract 216 from 220, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
72 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 9027.43
Deduct 0 from 40 and we're left 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.

Step 10:
If we divide 400 by 72, we get 5 and a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 9027.4305
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.

On to step 11:
The number 72 fits into 400 5 times, leaving a remainder of 40.
The next digit of our result is 5. 
Result so far: 9027.43055
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.

Our division results in 9027.43055 with a remaining 4e-05.
