Let's divide 641558 by 73
The aim is to understand the frequency of 73 in 641558.

Step 1:
73 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 73

Moving on to step 2:
The number 73 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (1) from the dividend, add it to 64, then carry on: 641 / 73

Step 3:
73 goes into 641 8 times with a remainder of 57.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 584 from 641 to get 57.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 73

Going ahead to step 4:
73 goes into 575 7 times with a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
If we take 511 away from 575, we end up with 64.
Take the next digit (5) from the dividend and append it to 64, then repeat: 645 / 73

Moving on to step 5:
645 divided by 73 is 8 with a remainder of 61.
Write down 8 as next digit of the result. 
Result so far: 878.0
Subtracting 584 from 645 leaves us with 61.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 73

Step 6:
73 can be fit into 618 8 times, resulting in a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 8788.0
The remainder is 34 after subtracting 584 from 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
73 goes into 340 4 times with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 8788.4
Deduct 292 from 340 and we're left 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.

On to step 8:
73 goes into 480 6 times with a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 8788.46
If we subtract 438 from 480, we 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 9:
420 divided by 73 is 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 8788.465
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.

Advancing to step 10:
The number 73 fits into 550 7 times, leaving a remainder of 39.
The next digit of our result is 7. 
Result so far: 8788.4657
Subtracting 511 from 550 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 11:
When dividing 390 by 73, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 8788.46575
Subtract 365 from 390 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
250 divided by 73 is 3 with a remainder of 31.
The next digit of our result is 3. 
Result so far: 8788.465753
If we subtract 219 from 250, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
73 can be fit into 310 4 times, resulting in a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 8788.4657534
Deduct 292 from 310 and we're left 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.

Let's proceed to step 14:
73 can be fit into 180 2 times, resulting in a remainder of 34.
The next digit of our result is 2. 
Result so far: 8788.46575342
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.

The quotient of the division is 8788.46575342, and the remainder is 3.4e-08.
