We look at the division of 73305747 by 872 
The aim is to understand the frequency of 872 in 73305747.

Going ahead to step 1:
872 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 872

Step 2:
The number 872 fits into 73 0 times, leaving a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Append the next digit (3) from the dividend to 73 and continue with: 733 / 872

Advancing to step 3:
733 divided by 872 is 0 with a remainder of 733.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 733 after subtracting 0 from 733.
Grab the next digit (0) from the dividend, add it to 733, then carry on: 7330 / 872

On to step 4:
872 can be fit into 7330 8 times, resulting in a remainder of 354.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 6976 from 7330 to get 354.
Bring next digit (5) of the dividend behind the 354 and repeat the process: 3545 / 872

Moving on to step 5:
When dividing 3545 by 872, we get 4 with a remainder of 57.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtracting 3488 from 3545 leaves us with 57.
Fetch the next digit (7) from the dividend, attach it to 57 and continue: 577 / 872

Step 6:
The number 872 fits into 577 0 times, leaving a remainder of 577.
Write down 0 as next digit of the result. 
Result so far: 840.0
Subtract 0 from 577 to get 577.
Take the next digit (4) from the dividend and append it to 577, then repeat: 5774 / 872

On to step 7:
872 can be fit into 5774 6 times, resulting in a remainder of 542.
Record the quotient 6 as the next digit in the result. 
Result so far: 8406.0
Deduct 5232 from 5774 and we're left with 542.
Grab the next digit (7) from the dividend, add it to 542, then carry on: 5427 / 872

Advancing to step 8:
The number 872 fits into 5427 6 times, leaving a remainder of 195.
Use 6 as the next digit of our solution. 
Result so far: 84066.0
Deduct 5232 from 5427 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 9:
If we divide 1950 by 872, we get 2 and a remainder of 206.
Use 2 as the next digit of our solution. 
Result so far: 84066.2
Subtracting 1744 from 1950 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 10:
If we divide 2060 by 872, we get 2 and a remainder of 316.
The number 2 becomes the next digit in our result. 
Result so far: 84066.22
If we subtract 1744 from 2060, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

The final result is 84066.22 with a remainder of 0.316.
