We're dividing 399331 by 73 
The aim is to understand the frequency of 73 in 399331.

Moving on to step 1:
73 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 73

Moving on to step 2:
73 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 73

Let's proceed to step 3:
399 divided by 73 is 5 with a remainder of 34.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 34 after subtracting 365 from 399.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 73

Advancing to step 4:
If we divide 343 by 73, we get 4 and a remainder of 51.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Subtracting 292 from 343 leaves us with 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 73

On to step 5:
73 goes into 513 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 547.0
The remainder is 2 after subtracting 511 from 513.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 73

On to step 6:
21 divided by 73 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 5470.0
If we take 0 away from 21, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
73 goes into 210 2 times with a remainder of 64.
The next digit of our result is 2. 
Result so far: 5470.2
If we take 146 away from 210, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 8:
73 can be fit into 640 8 times, resulting in a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 5470.28
If we take 584 away from 640, we end up 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.

Step 9:
If we divide 560 by 73, we get 7 and a remainder of 49.
The next digit of our result is 7. 
Result so far: 5470.287
If we subtract 511 from 560, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 10:
73 goes into 490 6 times with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 5470.2876
The remainder is 52 after subtracting 438 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 11:
520 divided by 73 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 5470.28767
If we subtract 511 from 520, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 12:
The number 73 fits into 90 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 5470.287671
If we subtract 73 from 90, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 13:
73 goes into 170 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 5470.2876712
Subtracting 146 from 170 leaves us 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.

Step 14:
73 goes into 240 3 times with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 5470.28767123
The remainder is 21 after subtracting 219 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

In conclusion, the division gives 5470.28767123 with a balance of 2.1e-08.
