38935954 ÷ 73 
The aim is to understand the frequency of 73 in 38935954.

Let's proceed to step 1:
If we divide 3 by 73, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 73

Step 2:
If we divide 38 by 73, we get 0 and a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Grab the next digit (9) from the dividend, add it to 38, then carry on: 389 / 73

Moving on to step 3:
If we divide 389 by 73, we get 5 and a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 365 away from 389, we end up with 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 73

Moving on to step 4:
If we divide 243 by 73, we get 3 and a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
Deduct 219 from 243 and we're left with 24.
Fetch the next digit (5) from the dividend, attach it to 24 and continue: 245 / 73

Advancing to step 5:
73 can be fit into 245 3 times, resulting in a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 533.0
The remainder is 26 after subtracting 219 from 245.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 73

On to step 6:
73 can be fit into 269 3 times, resulting in a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 5333.0
The remainder is 50 after subtracting 219 from 269.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 73

Let's proceed to step 7:
73 goes into 505 6 times with a remainder of 67.
Record the quotient 6 as the next digit in the result. 
Result so far: 53336.0
Subtracting 438 from 505 leaves us with 67.
Bring next digit (4) of the dividend behind the 67 and repeat the process: 674 / 73

On to step 8:
674 divided by 73 is 9 with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 533369.0
The remainder is 17 after subtracting 657 from 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
73 can be fit into 170 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 533369.2
The remainder is 24 after subtracting 146 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
If we divide 240 by 73, we get 3 and a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 533369.23
Subtracting 219 from 240 leaves us 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 11:
210 divided by 73 is 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 533369.232
Deduct 146 from 210 and we're left 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 12:
When dividing 640 by 73, we get 8 with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 533369.2328
Deduct 584 from 640 and we're left 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 13:
73 goes into 560 7 times with a remainder of 49.
The next digit of our result is 7. 
Result so far: 533369.23287
Subtract 511 from 560 to 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.

Advancing to step 14:
73 goes into 490 6 times with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 533369.232876
If we subtract 438 from 490, we 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.

Step 15:
The number 73 fits into 520 7 times, leaving a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 533369.2328767
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.

Going ahead to step 16:
73 goes into 90 1 times with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 533369.23287671
Subtract 73 from 90 to 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.

The final outcome is 533369.23287671, with a leftover of 1.7e-08.
