We're dividing 563987 by 73 
The aim is to understand the frequency of 73 in 563987.

On to step 1:
5 divided by 73 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 73

On to step 2:
73 goes into 56 0 times with a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Append the next digit (3) from the dividend to 56 and continue with: 563 / 73

Step 3:
The number 73 fits into 563 7 times, leaving a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 511 from 563 leaves us with 52.
Bring next digit (9) of the dividend behind the 52 and repeat the process: 529 / 73

Going ahead to step 4:
If we divide 529 by 73, we get 7 and a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
Deduct 511 from 529 and we're left with 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 73

On to step 5:
73 goes into 188 2 times with a remainder of 42.
The next digit of our result is 2. 
Result so far: 772.0
Deduct 146 from 188 and we're left with 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 73

Step 6:
The number 73 fits into 427 5 times, leaving a remainder of 62.
The number 5 becomes the next digit in our result. 
Result so far: 7725.0
The remainder is 62 after subtracting 365 from 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 7:
620 divided by 73 is 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 7725.8
The remainder is 36 after subtracting 584 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
360 divided by 73 is 4 with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 7725.84
Subtract 292 from 360 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
73 goes into 680 9 times with a remainder of 23.
The next digit of our result is 9. 
Result so far: 7725.849
If we take 657 away from 680, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 10:
73 can be fit into 230 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 7725.8493
Subtracting 219 from 230 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
73 goes into 110 1 times with a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 7725.84931
If we subtract 73 from 110, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 12:
When dividing 370 by 73, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 7725.849315
Subtracting 365 from 370 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 13:
If we divide 50 by 73, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 7725.849315
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
500 divided by 73 is 6 with a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 7725.84931506
If we subtract 438 from 500, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

In conclusion, the division gives 7725.84931506 with a balance of 6.2e-08.
