We look at the division of 197812 by 73 
The aim is to understand the frequency of 73 in 197812.

Advancing to step 1:
The number 73 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 73

Let's proceed to step 2:
When dividing 19 by 73, we get 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 73

Let's proceed to step 3:
73 can be fit into 197 2 times, resulting in a remainder of 51.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 146 from 197 and we're left with 51.
Fetch the next digit (8) from the dividend, attach it to 51 and continue: 518 / 73

Moving on to step 4:
If we divide 518 by 73, we get 7 and a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we subtract 511 from 518, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 73

Going ahead to step 5:
The number 73 fits into 71 0 times, leaving a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 270.0
Subtracting 0 from 71 leaves us with 71.
Grab the next digit (2) from the dividend, add it to 71, then carry on: 712 / 73

Moving on to step 6:
712 divided by 73 is 9 with a remainder of 55.
The next digit of our result is 9. 
Result so far: 2709.0
If we take 657 away from 712, we end up 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.

Moving on to step 7:
550 divided by 73 is 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 2709.7
If we take 511 away from 550, we end up 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.

Advancing to step 8:
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: 2709.75
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 9:
73 goes into 250 3 times with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 2709.753
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.

On to step 10:
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: 2709.7534
Subtracting 292 from 310 leaves us 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.

Going ahead to step 11:
73 goes into 180 2 times with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 2709.75342
Subtracting 146 from 180 leaves us 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 12:
When dividing 340 by 73, we get 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 2709.753424
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 13:
480 divided by 73 is 6 with a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 2709.7534246
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.

Moving on to step 14:
73 can be fit into 420 5 times, resulting in a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 2709.75342465
Subtracting 365 from 420 leaves us 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.

The quotient of the division is 2709.75342465, and the remainder is 5.5e-08.
