We look at the division of 357474 by 73 
The aim is to understand the frequency of 73 in 357474.

Step 1:
When dividing 3 by 73, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 73

On to step 2:
The number 73 fits into 35 0 times, leaving a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 73

Let's proceed to step 3:
73 can be fit into 357 4 times, resulting in a remainder of 65.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 292 away from 357, we end up with 65.
Take the next digit (4) from the dividend and append it to 65, then repeat: 654 / 73

Moving on to step 4:
73 goes into 654 8 times with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we subtract 584 from 654, we get 70.
Fetch the next digit (7) from the dividend, attach it to 70 and continue: 707 / 73

Advancing to step 5:
73 goes into 707 9 times with a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 489.0
Subtract 657 from 707 to get 50.
Take the next digit (4) from the dividend and append it to 50, then repeat: 504 / 73

On to step 6:
If we divide 504 by 73, we get 6 and a remainder of 66.
Write down 6 as next digit of the result. 
Result so far: 4896.0
Deduct 438 from 504 and we're left 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.

On to step 7:
73 can be fit into 660 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 4896.9
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 8:
The number 73 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 4896.9
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
73 goes into 300 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 4896.904
Subtracting 292 from 300 leaves us 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.

On to step 10:
80 divided by 73 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 4896.9041
Subtracting 73 from 80 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 11:
73 goes into 70 0 times with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 4896.9041
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.

Moving on to step 12:
The number 73 fits into 700 9 times, leaving a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 4896.904109
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.

Let's proceed to step 13:
73 goes into 430 5 times with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 4896.9041095
Subtracting 365 from 430 leaves us 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 14:
73 can be fit into 650 8 times, resulting in a remainder of 66.
The next digit of our result is 8. 
Result so far: 4896.90410958
If we take 584 away from 650, we end up 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.

The final outcome is 4896.90410958, with a leftover of 6.6e-08.
