Let's divide 126069 by 72
The aim is to understand the frequency of 72 in 126069.

Going ahead to step 1:
The number 72 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 72

Step 2:
If we divide 12 by 72, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 72

Step 3:
72 goes into 126 1 times with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 72 from 126 to get 54.
Append the next digit (0) from the dividend to 54 and continue with: 540 / 72

Going ahead to step 4:
72 goes into 540 7 times with a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 504 from 540, we get 36.
Bring next digit (6) of the dividend behind the 36 and repeat the process: 366 / 72

Going ahead to step 5:
72 can be fit into 366 5 times, resulting in a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 175.0
Subtracting 360 from 366 leaves us with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 72

Advancing to step 6:
72 goes into 69 0 times with a remainder of 69.
The next digit of our result is 0. 
Result so far: 1750.0
Subtracting 0 from 69 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 7:
When dividing 690 by 72, we get 9 with a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 1750.9
The remainder is 42 after subtracting 648 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
420 divided by 72 is 5 with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 1750.95
Deduct 360 from 420 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
The number 72 fits into 600 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 1750.958
Subtracting 576 from 600 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
When dividing 240 by 72, we get 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 1750.9583
If we take 216 away from 240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
If we divide 240 by 72, we get 3 and a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 1750.95833
Deduct 216 from 240 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 1750.95833 with a remaining 2.4e-05.
