18922606 ÷ 73 
The aim is to understand the frequency of 73 in 18922606.

Let's proceed to step 1:
When dividing 1 by 73, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 73

On to step 2:
18 divided by 73 is 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 73

Moving on to step 3:
73 goes into 189 2 times with a remainder of 43.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 146 from 189 and we're left with 43.
Grab the next digit (2) from the dividend, add it to 43, then carry on: 432 / 73

Moving on to step 4:
432 divided by 73 is 5 with a remainder of 67.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 67 after subtracting 365 from 432.
Bring next digit (2) of the dividend behind the 67 and repeat the process: 672 / 73

Moving on to step 5:
73 goes into 672 9 times with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 259.0
Subtract 657 from 672 to get 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 73

On to step 6:
156 divided by 73 is 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2592.0
Deduct 146 from 156 and we're left with 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 73

Going ahead to step 7:
The number 73 fits into 100 1 times, leaving a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 25921.0
The remainder is 27 after subtracting 73 from 100.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 73

Advancing to step 8:
276 divided by 73 is 3 with a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 259213.0
Subtracting 219 from 276 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 9:
73 goes into 570 7 times with a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 259213.7
Subtracting 511 from 570 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 10:
590 divided by 73 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 259213.78
If we take 584 away from 590, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
73 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 259213.78
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
If we divide 600 by 73, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 259213.7808
Subtract 584 from 600 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
If we divide 160 by 73, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 259213.78082
If we take 146 away from 160, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
73 can be fit into 140 1 times, resulting in a remainder of 67.
The number 1 becomes the next digit in our result. 
Result so far: 259213.780821
If we take 73 away from 140, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 15:
670 divided by 73 is 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 259213.7808219
Subtract 657 from 670 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 16:
When dividing 130 by 73, we get 1 with a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 259213.78082191
Deduct 73 from 130 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

After the division, we end up with 259213.78082191 and a remainder of 5.7e-08.
