725785 ÷ 73 
The aim is to understand the frequency of 73 in 725785.

Step 1:
When dividing 7 by 73, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 73

Going ahead to step 2:
When dividing 72 by 73, we get 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Grab the next digit (5) from the dividend, add it to 72, then carry on: 725 / 73

Moving on to step 3:
When dividing 725 by 73, we get 9 with a remainder of 68.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 657 away from 725, we end up with 68.
Include the next digit (7) from the dividend after 68, then repeat: 687 / 73

On to step 4:
When dividing 687 by 73, we get 9 with a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 99.0
If we subtract 657 from 687, we get 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 73

On to step 5:
If we divide 308 by 73, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 994.0
Subtracting 292 from 308 leaves us with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 73

On to step 6:
165 divided by 73 is 2 with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 9942.0
Subtracting 146 from 165 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
The number 73 fits into 190 2 times, leaving a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 9942.2
The remainder is 44 after subtracting 146 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
The number 73 fits into 440 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 9942.26
Deduct 438 from 440 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
If we divide 20 by 73, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 9942.26
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
73 goes into 200 2 times with a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 9942.2602
The remainder is 54 after subtracting 146 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 11:
If we divide 540 by 73, we get 7 and a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 9942.26027
The remainder is 29 after subtracting 511 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 12:
290 divided by 73 is 3 with a remainder of 71.
The next digit of our result is 3. 
Result so far: 9942.260273
Subtracting 219 from 290 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 13:
If we divide 710 by 73, we get 9 and a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 9942.2602739
Subtract 657 from 710 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 14:
The number 73 fits into 530 7 times, leaving a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 9942.26027397
Subtract 511 from 530 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 9942.26027397, and the remainder is 1.9e-08.
