We divide 754331 by 72
The aim is to understand the frequency of 72 in 754331.

Step 1:
When dividing 7 by 72, we get 0 with 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.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 72

On to step 2:
The number 72 fits into 75 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 72 from 75 to get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 72

Step 3:
When dividing 34 by 72, we get 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 34 and we're left with 34.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 72

Going ahead to step 4:
72 can be fit into 343 4 times, resulting in a remainder of 55.
Put 4 as the next digit of the answer. 
Result so far: 104.0
If we take 288 away from 343, we end up with 55.
Include the next digit (3) from the dividend after 55, then repeat: 553 / 72

Let's proceed to step 5:
553 divided by 72 is 7 with a remainder of 49.
The next digit of our result is 7. 
Result so far: 1047.0
Deduct 504 from 553 and we're left with 49.
Include the next digit (1) from the dividend after 49, then repeat: 491 / 72

On to step 6:
The number 72 fits into 491 6 times, leaving a remainder of 59.
Record the quotient 6 as the next digit in the result. 
Result so far: 10476.0
Deduct 432 from 491 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 7:
If we divide 590 by 72, we get 8 and a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 10476.8
Subtract 576 from 590 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
72 goes into 140 1 times with a remainder of 68.
Record the quotient 1 as the next digit in the result. 
Result so far: 10476.81
If we subtract 72 from 140, 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.

Going ahead to step 9:
The number 72 fits into 680 9 times, leaving a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 10476.819
If we take 648 away from 680, we end up 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.

Going ahead to step 10:
320 divided by 72 is 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 10476.8194
If we take 288 away from 320, we end up 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 11:
When dividing 320 by 72, we get 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 10476.81944
Deduct 288 from 320 and we're left 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.

After the division, we end up with 10476.81944 and a remainder of 3.2e-05.
