We look at the division of 494478 by 73 
The aim is to understand the frequency of 73 in 494478.

On to step 1:
When dividing 4 by 73, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 73

Let's proceed to step 2:
When dividing 49 by 73, we get 0 with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Grab the next digit (4) from the dividend, add it to 49, then carry on: 494 / 73

Moving on to step 3:
73 can be fit into 494 6 times, resulting in a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 438 from 494 leaves us with 56.
Append the next digit (4) from the dividend to 56 and continue with: 564 / 73

On to step 4:
If we divide 564 by 73, we get 7 and a remainder of 53.
The next digit of our result is 7. 
Result so far: 67.0
Subtracting 511 from 564 leaves us with 53.
Append the next digit (7) from the dividend to 53 and continue with: 537 / 73

Moving on to step 5:
If we divide 537 by 73, we get 7 and a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 677.0
If we subtract 511 from 537, we get 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 73

Step 6:
73 goes into 268 3 times with a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 6773.0
If we take 219 away from 268, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
490 divided by 73 is 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 6773.6
Subtracting 438 from 490 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 8:
The number 73 fits into 520 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 6773.67
Subtracting 511 from 520 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
When dividing 90 by 73, we get 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 6773.671
If we subtract 73 from 90, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
73 can be fit into 170 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 6773.6712
If we subtract 146 from 170, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
The number 73 fits into 240 3 times, leaving a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 6773.67123
The remainder is 21 after subtracting 219 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 12:
If we divide 210 by 73, we get 2 and a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 6773.671232
The remainder is 64 after subtracting 146 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
73 can be fit into 640 8 times, resulting in a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 6773.6712328
If we subtract 584 from 640, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 14:
The number 73 fits into 560 7 times, leaving a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 6773.67123287
If we take 511 away from 560, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final result is 6773.67123287 with a remainder of 4.9e-08.
