We look at the division of 17646468 by 73 
The aim is to understand the frequency of 73 in 17646468.

Advancing to step 1:
When dividing 1 by 73, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 73

On to step 2:
The number 73 fits into 17 0 times, leaving a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 73

On to step 3:
73 goes into 176 2 times with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 146 from 176, we get 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 73

Going ahead to step 4:
73 can be fit into 304 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtract 292 from 304 to get 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 73

Going ahead to step 5:
126 divided by 73 is 1 with a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 241.0
If we take 73 away from 126, we end up with 53.
Fetch the next digit (4) from the dividend, attach it to 53 and continue: 534 / 73

On to step 6:
73 goes into 534 7 times with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 2417.0
Subtract 511 from 534 to get 23.
Append the next digit (6) from the dividend to 23 and continue with: 236 / 73

Let's proceed to step 7:
73 goes into 236 3 times with a remainder of 17.
The next digit of our result is 3. 
Result so far: 24173.0
Subtracting 219 from 236 leaves us with 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 73

Advancing to step 8:
73 can be fit into 178 2 times, resulting in a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 241732.0
Subtracting 146 from 178 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 9:
If we divide 320 by 73, we get 4 and a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 241732.4
The remainder is 28 after subtracting 292 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
If we divide 280 by 73, we get 3 and a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 241732.43
Deduct 219 from 280 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 11:
The number 73 fits into 610 8 times, leaving a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 241732.438
Deduct 584 from 610 and we're left 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.

Going ahead to step 12:
260 divided by 73 is 3 with a remainder of 41.
The next digit of our result is 3. 
Result so far: 241732.4383
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 13:
The number 73 fits into 410 5 times, leaving a remainder of 45.
The next digit of our result is 5. 
Result so far: 241732.43835
If we subtract 365 from 410, 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 14:
450 divided by 73 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 241732.438356
Subtracting 438 from 450 leaves us 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.

Step 15:
When dividing 120 by 73, we get 1 with a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 241732.4383561
Subtract 73 from 120 to get 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 16:
470 divided by 73 is 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 241732.43835616
If we subtract 438 from 470, we get 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 241732.43835616 with a balance of 3.2e-08.
