We look at the division of 877200 by 73 
The aim is to understand the frequency of 73 in 877200.

Going ahead to step 1:
73 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 73

Advancing to step 2:
When dividing 87 by 73, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 73 from 87 leaves us with 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 73

Advancing to step 3:
If we divide 147 by 73, we get 2 and a remainder of 1.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 146 from 147, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 73

Going ahead to step 4:
73 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 120.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 73

Let's proceed to step 5:
The number 73 fits into 120 1 times, leaving a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 1201.0
If we take 73 away from 120, we end up with 47.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 73

On to step 6:
470 divided by 73 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 12016.0
Subtracting 438 from 470 leaves us 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 7:
When dividing 320 by 73, we get 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 12016.4
If we take 292 away from 320, we end up 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.

Let's proceed to step 8:
The number 73 fits into 280 3 times, leaving a remainder of 61.
Write down 3 as next digit of the result. 
Result so far: 12016.43
If we subtract 219 from 280, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 9:
73 can be fit into 610 8 times, resulting in a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 12016.438
Subtract 584 from 610 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
260 divided by 73 is 3 with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 12016.4383
If we subtract 219 from 260, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 11:
When dividing 410 by 73, we get 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 12016.43835
Subtracting 365 from 410 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 12:
73 can be fit into 450 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 12016.438356
Deduct 438 from 450 and we're left 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.

Advancing to step 13:
The number 73 fits into 120 1 times, leaving a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 12016.4383561
Subtracting 73 from 120 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 14:
73 can be fit into 470 6 times, resulting in a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 12016.43835616
If we take 438 away from 470, 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.

In conclusion, the division gives 12016.43835616 with a balance of 3.2e-08.
