Let's divide 428439 by 73
The aim is to understand the frequency of 73 in 428439.

Let's proceed to step 1:
The number 73 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 73

Moving on to step 2:
73 can be fit into 42 0 times, resulting in a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 73

Going ahead to step 3:
73 goes into 428 5 times with a remainder of 63.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 365 away from 428, we end up with 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 73

Step 4:
73 can be fit into 634 8 times, resulting in a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 58.0
If we take 584 away from 634, we end up with 50.
Append the next digit (3) from the dividend to 50 and continue with: 503 / 73

Step 5:
The number 73 fits into 503 6 times, leaving a remainder of 65.
Put 6 as the next digit of the answer. 
Result so far: 586.0
Subtract 438 from 503 to get 65.
Bring next digit (9) of the dividend behind the 65 and repeat the process: 659 / 73

Advancing to step 6:
659 divided by 73 is 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 5869.0
Subtracting 657 from 659 leaves us 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.

Let's proceed to step 7:
20 divided by 73 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 5869.0
If we take 0 away from 20, we end up with 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 8:
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: 5869.02
Deduct 146 from 200 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
When dividing 540 by 73, we get 7 with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 5869.027
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.

On to step 10:
73 can be fit into 290 3 times, resulting in a remainder of 71.
Put 3 as the next digit of the answer. 
Result so far: 5869.0273
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.

Going ahead to step 11:
710 divided by 73 is 9 with a remainder of 53.
The number 9 becomes the next digit in our result. 
Result so far: 5869.02739
Deduct 657 from 710 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 12:
The number 73 fits into 530 7 times, leaving a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 5869.027397
If we subtract 511 from 530, we 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.

On to step 13:
If we divide 190 by 73, we get 2 and a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 5869.0273972
Subtract 146 from 190 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 14:
440 divided by 73 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 5869.02739726
If we take 438 away from 440, we end up 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.

The final result is 5869.02739726 with a remainder of 2e-09.
