We're dividing 339874 by 72 
The aim is to understand the frequency of 72 in 339874.

Moving on to step 1:
The number 72 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 72

Going ahead to step 2:
33 divided by 72 is 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Append the next digit (9) from the dividend to 33 and continue with: 339 / 72

Moving on to step 3:
339 divided by 72 is 4 with a remainder of 51.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 288 from 339, we get 51.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 72

On to step 4:
When dividing 518 by 72, we get 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we subtract 504 from 518, we get 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 72

On to step 5:
When dividing 147 by 72, we get 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 472.0
The remainder is 3 after subtracting 144 from 147.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 72

Let's proceed to step 6:
If we divide 34 by 72, we get 0 and a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 4720.0
If we take 0 away from 34, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 7:
72 goes into 340 4 times with a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 4720.4
The remainder is 52 after subtracting 288 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 8:
72 goes into 520 7 times with a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 4720.47
If we take 504 away from 520, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
When dividing 160 by 72, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 4720.472
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
When dividing 160 by 72, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 4720.4722
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 4720.4722 and a remainder of 0.00016.
