We look at the division of 194519 by 72 
The aim is to understand the frequency of 72 in 194519.

On to step 1:
If we divide 1 by 72, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 72

Step 2:
19 divided by 72 is 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 72

Advancing to step 3:
72 can be fit into 194 2 times, resulting in a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 144 from 194 leaves us with 50.
Fetch the next digit (5) from the dividend, attach it to 50 and continue: 505 / 72

Let's proceed to step 4:
The number 72 fits into 505 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 27.0
If we take 504 away from 505, we end up with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 72

Let's proceed to step 5:
When dividing 11 by 72, we get 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 270.0
If we subtract 0 from 11, we get 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 72

Going ahead to step 6:
72 can be fit into 119 1 times, resulting in a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 2701.0
The remainder is 47 after subtracting 72 from 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
When dividing 470 by 72, we get 6 with a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 2701.6
Subtracting 432 from 470 leaves us 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.

Going ahead to step 8:
If we divide 380 by 72, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 2701.65
If we take 360 away from 380, we end up with 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:
72 goes into 200 2 times with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 2701.652
Deduct 144 from 200 and we're left 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.

Advancing 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: 2701.6527
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.

Advancing to step 11:
560 divided by 72 is 7 with a remainder of 56.
The next digit of our result is 7. 
Result so far: 2701.65277
The remainder is 56 after subtracting 504 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

In conclusion, the division gives 2701.65277 with a balance of 5.6e-05.
