We're dividing 640526 by 73 
The aim is to understand the frequency of 73 in 640526.

Let's proceed to step 1:
The number 73 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 73

Let's proceed to step 2:
64 divided by 73 is 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (0) from the dividend to 64 and continue with: 640 / 73

On to step 3:
When dividing 640 by 73, we get 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 584 from 640, we get 56.
Append the next digit (5) from the dividend to 56 and continue with: 565 / 73

Moving on to step 4:
73 goes into 565 7 times with a remainder of 54.
The next digit of our result is 7. 
Result so far: 87.0
Subtract 511 from 565 to get 54.
Append the next digit (2) from the dividend to 54 and continue with: 542 / 73

Let's proceed to step 5:
73 can be fit into 542 7 times, resulting in a remainder of 31.
The next digit of our result is 7. 
Result so far: 877.0
Subtracting 511 from 542 leaves us with 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 73

Moving on to step 6:
The number 73 fits into 316 4 times, leaving a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 8774.0
Subtract 292 from 316 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
The number 73 fits into 240 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 8774.3
Subtract 219 from 240 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 8:
210 divided by 73 is 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 8774.32
The remainder is 64 after subtracting 146 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
73 goes into 640 8 times with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 8774.328
Subtracting 584 from 640 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 10:
73 goes into 560 7 times with a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 8774.3287
The remainder is 49 after subtracting 511 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 11:
If we divide 490 by 73, we get 6 and a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 8774.32876
Subtract 438 from 490 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 12:
When dividing 520 by 73, we get 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 8774.328767
If we take 511 away from 520, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
If we divide 90 by 73, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 8774.3287671
The remainder is 17 after subtracting 73 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 14:
73 goes into 170 2 times with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 8774.32876712
If we take 146 away from 170, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 8774.32876712 with a balance of 2.4e-08.
