We're dividing 751069 by 72 
The aim is to understand the frequency of 72 in 751069.

Advancing to step 1:
72 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 72

On to step 2:
If we divide 75 by 72, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 72 away from 75, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 72

Step 3:
If we divide 31 by 72, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 31, we end up with 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 72

Let's proceed to step 4:
When dividing 310 by 72, we get 4 with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 104.0
Subtracting 288 from 310 leaves us with 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 72

On to step 5:
72 goes into 226 3 times with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 1043.0
Subtract 216 from 226 to get 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 72

Going ahead to step 6:
109 divided by 72 is 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 10431.0
Subtracting 72 from 109 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
The number 72 fits into 370 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 10431.5
The remainder is 10 after subtracting 360 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
72 goes into 100 1 times with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 10431.51
Deduct 72 from 100 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
72 goes into 280 3 times with a remainder of 64.
The next digit of our result is 3. 
Result so far: 10431.513
Subtract 216 from 280 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
If we divide 640 by 72, we get 8 and a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 10431.5138
Subtracting 576 from 640 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 11:
When dividing 640 by 72, we get 8 with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 10431.51388
If we take 576 away from 640, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 10431.51388 with a remaining 6.4e-05.
