501992 ÷ 38 
The aim is to understand the frequency of 38 in 501992.

Let's proceed to step 1:
When dividing 5 by 38, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 38

Advancing to step 2:
When dividing 50 by 38, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 38 from 50, we get 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 38

Going ahead to step 3:
If we divide 121 by 38, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 7 after subtracting 114 from 121.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 38

Going ahead to step 4:
79 divided by 38 is 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 132.0
If we take 76 away from 79, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 38

Let's proceed to step 5:
38 goes into 39 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1321.0
The remainder is 1 after subtracting 38 from 39.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 38

Moving on to step 6:
38 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 13210.0
Subtract 0 from 12 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
The number 38 fits into 120 3 times, leaving a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 13210.3
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
When dividing 60 by 38, we get 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 13210.31
Subtract 38 from 60 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
If we divide 220 by 38, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 13210.315
If we take 190 away from 220, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
38 can be fit into 300 7 times, resulting in a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 13210.3157
Subtracting 266 from 300 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
When dividing 340 by 38, we get 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 13210.31578
Deduct 304 from 340 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
38 goes into 360 9 times with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 13210.315789
If we take 342 away from 360, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
38 goes into 180 4 times with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 13210.3157894
The remainder is 28 after subtracting 152 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
When dividing 280 by 38, we get 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 13210.31578947
The remainder is 14 after subtracting 266 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 13210.31578947 and a remainder of 1.4e-08.
