We're dividing 170348 by 72 
The aim is to understand the frequency of 72 in 170348.

Moving on to step 1:
The number 72 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 72

On to step 2:
The number 72 fits into 17 0 times, leaving a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 72

Moving on to step 3:
If we divide 170 by 72, we get 2 and a remainder of 26.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 144 from 170, we get 26.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 72

Let's proceed to step 4:
72 goes into 263 3 times with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we take 216 away from 263, we end up with 47.
Take the next digit (4) from the dividend and append it to 47, then repeat: 474 / 72

Let's proceed to step 5:
When dividing 474 by 72, we get 6 with a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 236.0
Deduct 432 from 474 and we're left with 42.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 72

Let's proceed to step 6:
The number 72 fits into 428 5 times, leaving a remainder of 68.
Use 5 as the next digit of our solution. 
Result so far: 2365.0
If we subtract 360 from 428, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 7:
72 goes into 680 9 times with a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 2365.9
Subtracting 648 from 680 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.

Advancing to step 8:
If we divide 320 by 72, we get 4 and a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 2365.94
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
72 goes into 320 4 times with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 2365.944
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 2365.944, and the remainder is 0.0032.
