172456 ÷ 73 
The aim is to understand the frequency of 73 in 172456.

Step 1:
When dividing 1 by 73, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 73

Step 2:
When dividing 17 by 73, we get 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 73

Going ahead to step 3:
If we divide 172 by 73, we get 2 and a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 146 from 172 and we're left with 26.
Grab the next digit (4) from the dividend, add it to 26, then carry on: 264 / 73

Advancing to step 4:
The number 73 fits into 264 3 times, leaving a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Deduct 219 from 264 and we're left with 45.
Include the next digit (5) from the dividend after 45, then repeat: 455 / 73

Let's proceed to step 5:
455 divided by 73 is 6 with a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 236.0
Deduct 438 from 455 and we're left with 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 73

Moving on to step 6:
When dividing 176 by 73, we get 2 with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 2362.0
Subtracting 146 from 176 leaves us 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.

Advancing to step 7:
When dividing 300 by 73, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 2362.4
Deduct 292 from 300 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
The number 73 fits into 80 1 times, leaving a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 2362.41
Subtract 73 from 80 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
73 can be fit into 70 0 times, resulting in a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 2362.41
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
700 divided by 73 is 9 with a remainder of 43.
The next digit of our result is 9. 
Result so far: 2362.4109
Subtracting 657 from 700 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 11:
If we divide 430 by 73, we get 5 and a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 2362.41095
Deduct 365 from 430 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 12:
When dividing 650 by 73, we get 8 with a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 2362.410958
Subtracting 584 from 650 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 13:
The number 73 fits into 660 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 2362.4109589
Subtracting 657 from 660 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
73 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 2362.4109589
Subtracting 0 from 30 leaves us 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.

In conclusion, the division gives 2362.4109589 with a balance of 3e-08.
