We divide 757830 by 72
The aim is to understand the frequency of 72 in 757830.

Step 1:
The number 72 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 72

On to step 2:
The number 72 fits into 75 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 72 from 75 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 72

Going ahead to step 3:
When dividing 37 by 72, we get 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 37 leaves us with 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 72

Moving on to step 4:
When dividing 378 by 72, we get 5 with a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
Deduct 360 from 378 and we're left with 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 72

Going ahead to step 5:
72 can be fit into 183 2 times, resulting in a remainder of 39.
The next digit of our result is 2. 
Result so far: 1052.0
Subtract 144 from 183 to get 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 72

On to step 6:
When dividing 390 by 72, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 10525.0
Deduct 360 from 390 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
If we divide 300 by 72, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 10525.4
Subtracting 288 from 300 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
120 divided by 72 is 1 with a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 10525.41
If we subtract 72 from 120, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
If we divide 480 by 72, we get 6 and a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 10525.416
If we take 432 away from 480, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
The number 72 fits into 480 6 times, leaving a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 10525.4166
If we take 432 away from 480, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 10525.4166 with a remainder of 0.00048.
