We look at the division of 860861 by 73 
The aim is to understand the frequency of 73 in 860861.

Moving on to step 1:
The number 73 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 73

Moving on to step 2:
73 can be fit into 86 1 times, resulting in a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 73 from 86, we get 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 73

Moving on to step 3:
130 divided by 73 is 1 with a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 73 from 130 to get 57.
Grab the next digit (8) from the dividend, add it to 57, then carry on: 578 / 73

On to step 4:
The number 73 fits into 578 7 times, leaving a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 117.0
Subtracting 511 from 578 leaves us with 67.
Take the next digit (6) from the dividend and append it to 67, then repeat: 676 / 73

Going ahead to step 5:
If we divide 676 by 73, we get 9 and a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 1179.0
If we subtract 657 from 676, we get 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 73

Step 6:
The number 73 fits into 191 2 times, leaving a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 11792.0
If we subtract 146 from 191, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 7:
The number 73 fits into 450 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 11792.6
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 8:
73 can be fit into 120 1 times, resulting in a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 11792.61
Deduct 73 from 120 and we're left 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.

Let's proceed to step 9:
73 can be fit into 470 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 11792.616
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.

On to step 10:
If we divide 320 by 73, we get 4 and a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 11792.6164
Deduct 292 from 320 and we're left 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 11:
280 divided by 73 is 3 with a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 11792.61643
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.

Let's proceed to step 12:
The number 73 fits into 610 8 times, leaving a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 11792.616438
Subtracting 584 from 610 leaves us with 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 13:
When dividing 260 by 73, we get 3 with a remainder of 41.
The next digit of our result is 3. 
Result so far: 11792.6164383
Subtracting 219 from 260 leaves us with 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 14:
When dividing 410 by 73, we get 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 11792.61643835
Deduct 365 from 410 and we're left 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.

In conclusion, the division gives 11792.61643835 with a balance of 4.5e-08.
