We look at the division of 208965 by 73 
The aim is to understand the frequency of 73 in 208965.

Going ahead to step 1:
The number 73 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 73

Step 2:
73 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 73

Moving on to step 3:
If we divide 208 by 73, we get 2 and a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 146 away from 208, we end up with 62.
Append the next digit (9) from the dividend to 62 and continue with: 629 / 73

Going ahead to step 4:
73 goes into 629 8 times with a remainder of 45.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
The remainder is 45 after subtracting 584 from 629.
Append the next digit (6) from the dividend to 45 and continue with: 456 / 73

Advancing to step 5:
456 divided by 73 is 6 with a remainder of 18.
The next digit of our result is 6. 
Result so far: 286.0
If we take 438 away from 456, we end up with 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 73

Advancing to step 6:
When dividing 185 by 73, we get 2 with a remainder of 39.
Put 2 as the next digit of the answer. 
Result so far: 2862.0
Subtracting 146 from 185 leaves us 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.

Step 7:
73 goes into 390 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 2862.5
The remainder is 25 after subtracting 365 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
250 divided by 73 is 3 with a remainder of 31.
The next digit of our result is 3. 
Result so far: 2862.53
Subtracting 219 from 250 leaves us 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.

Going ahead to step 9:
When dividing 310 by 73, we get 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 2862.534
If we subtract 292 from 310, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
73 goes into 180 2 times with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 2862.5342
Deduct 146 from 180 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 11:
73 goes into 340 4 times with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 2862.53424
Subtract 292 from 340 to 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.

Step 12:
If we divide 480 by 73, we get 6 and a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 2862.534246
Subtracting 438 from 480 leaves us 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.

Step 13:
The number 73 fits into 420 5 times, leaving a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 2862.5342465
If we subtract 365 from 420, we 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.

Going ahead to step 14:
When dividing 550 by 73, we get 7 with a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 2862.53424657
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.

The final result is 2862.53424657 with a remainder of 3.9e-08.
