122575 divided by 72 
The aim is to understand the frequency of 72 in 122575.

On to step 1:
1 divided by 72 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 72

Moving on to step 2:
The number 72 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 72

Moving on to step 3:
72 goes into 122 1 times with a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 72 from 122 and we're left with 50.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 72

Advancing to step 4:
If we divide 505 by 72, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 504 away from 505, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 72

Going ahead to step 5:
The number 72 fits into 17 0 times, leaving a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 170.0
Subtract 0 from 17 to get 17.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 72

Step 6:
72 can be fit into 175 2 times, resulting in a remainder of 31.
The next digit of our result is 2. 
Result so far: 1702.0
If we take 144 away from 175, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
When dividing 310 by 72, we get 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 1702.4
Subtracting 288 from 310 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
The number 72 fits into 220 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 1702.43
If we subtract 216 from 220, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
72 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1702.43
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
The number 72 fits into 400 5 times, leaving a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 1702.4305
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
The number 72 fits into 400 5 times, leaving a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 1702.43055
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 1702.43055 with a balance of 4e-05.
