73150302 divided by 643 
The aim is to understand the frequency of 643 in 73150302.

Going ahead to step 1:
If we divide 7 by 643, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 643

Moving on to step 2:
The number 643 fits into 73 0 times, leaving a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Take the next digit (1) from the dividend and append it to 73, then repeat: 731 / 643

Step 3:
If we divide 731 by 643, we get 1 and a remainder of 88.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 643 from 731, we get 88.
Bring next digit (5) of the dividend behind the 88 and repeat the process: 885 / 643

On to step 4:
If we divide 885 by 643, we get 1 and a remainder of 242.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 643 from 885, we get 242.
Fetch the next digit (0) from the dividend, attach it to 242 and continue: 2420 / 643

Let's proceed to step 5:
The number 643 fits into 2420 3 times, leaving a remainder of 491.
Use 3 as the next digit of our solution. 
Result so far: 113.0
Subtracting 1929 from 2420 leaves us with 491.
Append the next digit (3) from the dividend to 491 and continue with: 4913 / 643

Going ahead to step 6:
If we divide 4913 by 643, we get 7 and a remainder of 412.
Record the quotient 7 as the next digit in the result. 
Result so far: 1137.0
If we take 4501 away from 4913, we end up with 412.
Append the next digit (0) from the dividend to 412 and continue with: 4120 / 643

Moving on to step 7:
The number 643 fits into 4120 6 times, leaving a remainder of 262.
The number 6 becomes the next digit in our result. 
Result so far: 11376.0
Deduct 3858 from 4120 and we're left with 262.
Append the next digit (2) from the dividend to 262 and continue with: 2622 / 643

Going ahead to step 8:
643 can be fit into 2622 4 times, resulting in a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 113764.0
Deduct 2572 from 2622 and we're left with 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 9:
500 divided by 643 is 0 with a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 113764.0
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 10:
5000 divided by 643 is 7 with a remainder of 499.
Write down 7 as next digit of the result. 
Result so far: 113764.07
If we subtract 4501 from 5000, we get 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Going ahead to step 11:
4990 divided by 643 is 7 with a remainder of 489.
The number 7 becomes the next digit in our result. 
Result so far: 113764.077
The remainder is 489 after subtracting 4501 from 4990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

In conclusion, the division gives 113764.077 with a balance of 0.0489.
