We're dividing 72809751 by 416 
The aim is to understand the frequency of 416 in 72809751.

Going ahead to step 1:
The number 416 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
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 416

Going ahead to step 2:
416 goes into 72 0 times with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Bring next digit (8) of the dividend behind the 72 and repeat the process: 728 / 416

Moving on to step 3:
416 can be fit into 728 1 times, resulting in a remainder of 312.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 416 from 728 and we're left with 312.
Take the next digit (0) from the dividend and append it to 312, then repeat: 3120 / 416

On to step 4:
416 can be fit into 3120 7 times, resulting in a remainder of 208.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 2912 from 3120 to get 208.
Bring next digit (9) of the dividend behind the 208 and repeat the process: 2089 / 416

Moving on to step 5:
416 goes into 2089 5 times with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 175.0
If we subtract 2080 from 2089, we get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 416

On to step 6:
When dividing 97 by 416, we get 0 with a remainder of 97.
The next digit of our result is 0. 
Result so far: 1750.0
If we subtract 0 from 97, we get 97.
Bring next digit (5) of the dividend behind the 97 and repeat the process: 975 / 416

Step 7:
The number 416 fits into 975 2 times, leaving a remainder of 143.
Put 2 as the next digit of the answer. 
Result so far: 17502.0
If we take 832 away from 975, we end up with 143.
Bring next digit (1) of the dividend behind the 143 and repeat the process: 1431 / 416

Moving on to step 8:
If we divide 1431 by 416, we get 3 and a remainder of 183.
Record the quotient 3 as the next digit in the result. 
Result so far: 175023.0
Subtracting 1248 from 1431 leaves us with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Going ahead to step 9:
416 can be fit into 1830 4 times, resulting in a remainder of 166.
The next digit of our result is 4. 
Result so far: 175023.4
The remainder is 166 after subtracting 1664 from 1830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 10:
When dividing 1660 by 416, we get 3 with a remainder of 412.
The next digit of our result is 3. 
Result so far: 175023.43
The remainder is 412 after subtracting 1248 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

On to step 11:
The number 416 fits into 4120 9 times, leaving a remainder of 376.
Put 9 as the next digit of the answer. 
Result so far: 175023.439
The remainder is 376 after subtracting 3744 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 12:
3760 divided by 416 is 9 with a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 175023.4399
Subtracting 3744 from 3760 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 175023.4399 with a remainder of 0.00016.
