We look at the division of 358326 by 73 
The aim is to understand the frequency of 73 in 358326.

Going ahead to step 1:
3 divided by 73 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 73

Going ahead to step 2:
73 goes into 35 0 times with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 73

On to step 3:
358 divided by 73 is 4 with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 66 after subtracting 292 from 358.
Fetch the next digit (3) from the dividend, attach it to 66 and continue: 663 / 73

Advancing to step 4:
When dividing 663 by 73, we get 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
Subtract 657 from 663 to get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 73

Going ahead to step 5:
62 divided by 73 is 0 with a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 490.0
Subtract 0 from 62 to get 62.
Fetch the next digit (6) from the dividend, attach it to 62 and continue: 626 / 73

Let's proceed to step 6:
The number 73 fits into 626 8 times, leaving a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 4908.0
Deduct 584 from 626 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
73 can be fit into 420 5 times, resulting in a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 4908.5
Deduct 365 from 420 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 8:
73 can be fit into 550 7 times, resulting in a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 4908.57
Deduct 511 from 550 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 9:
When dividing 390 by 73, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 4908.575
Subtracting 365 from 390 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 10:
73 can be fit into 250 3 times, resulting in a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 4908.5753
If we subtract 219 from 250, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 11:
When dividing 310 by 73, we get 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 4908.57534
Deduct 292 from 310 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
73 can be fit into 180 2 times, resulting in a remainder of 34.
The next digit of our result is 2. 
Result so far: 4908.575342
The remainder is 34 after subtracting 146 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 13:
73 goes into 340 4 times with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 4908.5753424
Deduct 292 from 340 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 14:
73 can be fit into 480 6 times, resulting in a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 4908.57534246
If we take 438 away from 480, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 4908.57534246, and the remainder is 4.2e-08.
