We look at the division of 351470 by 73 
The aim is to understand the frequency of 73 in 351470.

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

Advancing to step 2:
73 goes into 35 0 times with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 73

Let's proceed to step 3:
The number 73 fits into 351 4 times, leaving a remainder of 59.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 292 from 351 and we're left with 59.
Fetch the next digit (4) from the dividend, attach it to 59 and continue: 594 / 73

Going ahead to step 4:
If we divide 594 by 73, we get 8 and a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Deduct 584 from 594 and we're left with 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 73

Let's proceed to step 5:
If we divide 107 by 73, we get 1 and a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 481.0
If we subtract 73 from 107, we get 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 73

Advancing to step 6:
The number 73 fits into 340 4 times, leaving a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 4814.0
If we take 292 away from 340, we end up 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.

Moving on to step 7:
480 divided by 73 is 6 with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 4814.6
Subtract 438 from 480 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
When dividing 420 by 73, we get 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 4814.65
Subtract 365 from 420 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 9:
If we divide 550 by 73, we get 7 and a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 4814.657
The remainder is 39 after subtracting 511 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 10:
If we divide 390 by 73, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 4814.6575
If we take 365 away from 390, we end up 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.

On to step 11:
73 goes into 250 3 times with a remainder of 31.
The next digit of our result is 3. 
Result so far: 4814.65753
Deduct 219 from 250 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 12:
When dividing 310 by 73, we get 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 4814.657534
The remainder is 18 after subtracting 292 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
73 goes into 180 2 times with a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 4814.6575342
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.

Step 14:
73 goes into 340 4 times with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 4814.65753424
If we subtract 292 from 340, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 4814.65753424 with a remaining 4.8e-08.
