We're dividing 254243 by 72 
The aim is to understand the frequency of 72 in 254243.

Step 1:
When dividing 2 by 72, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 72

Advancing to step 2:
72 goes into 25 0 times with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Grab the next digit (4) from the dividend, add it to 25, then carry on: 254 / 72

Let's proceed to step 3:
254 divided by 72 is 3 with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 216 from 254 and we're left with 38.
Bring next digit (2) of the dividend behind the 38 and repeat the process: 382 / 72

Step 4:
The number 72 fits into 382 5 times, leaving a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Subtract 360 from 382 to get 22.
Append the next digit (4) from the dividend to 22 and continue with: 224 / 72

Step 5:
When dividing 224 by 72, we get 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 353.0
If we subtract 216 from 224, we get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 72

On to step 6:
83 divided by 72 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 3531.0
Subtracting 72 from 83 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
If we divide 110 by 72, we get 1 and a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 3531.1
Deduct 72 from 110 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
If we divide 380 by 72, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 3531.15
If we subtract 360 from 380, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
When dividing 200 by 72, we get 2 with a remainder of 56.
The next digit of our result is 2. 
Result so far: 3531.152
The remainder is 56 after subtracting 144 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
72 goes into 560 7 times with a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 3531.1527
Subtracting 504 from 560 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
72 can be fit into 560 7 times, resulting in a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 3531.15277
Subtract 504 from 560 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 3531.15277, and the remainder is 5.6e-05.
