Let's divide 261896 by 72
The aim is to understand the frequency of 72 in 261896.

Going ahead to step 1:
72 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 72

Step 2:
72 can be fit into 26 0 times, resulting in a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Take the next digit (1) from the dividend and append it to 26, then repeat: 261 / 72

Going ahead to step 3:
If we divide 261 by 72, we get 3 and a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 216 from 261 and we're left with 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 72

On to step 4:
72 can be fit into 458 6 times, resulting in a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Subtracting 432 from 458 leaves us with 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 72

Step 5:
72 can be fit into 269 3 times, resulting in a remainder of 53.
The next digit of our result is 3. 
Result so far: 363.0
If we take 216 away from 269, we end up with 53.
Bring next digit (6) of the dividend behind the 53 and repeat the process: 536 / 72

Advancing to step 6:
If we divide 536 by 72, we get 7 and a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 3637.0
Subtracting 504 from 536 leaves us 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.

Going ahead to step 7:
320 divided by 72 is 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 3637.4
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.

Going ahead to step 8:
72 goes into 320 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 3637.44
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 3637.44 with a remainder of 0.032.
