Let's divide 485969 by 38
The aim is to understand the frequency of 38 in 485969.

Going ahead to step 1:
If we divide 4 by 38, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 38

Step 2:
When dividing 48 by 38, we get 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 38 away from 48, we end up with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 38

Advancing to step 3:
If we divide 105 by 38, we get 2 and a remainder of 29.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 76 from 105 leaves us with 29.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 38

Moving on to step 4:
38 can be fit into 299 7 times, resulting in a remainder of 33.
The next digit of our result is 7. 
Result so far: 127.0
If we take 266 away from 299, we end up with 33.
Bring next digit (6) of the dividend behind the 33 and repeat the process: 336 / 38

On to step 5:
38 goes into 336 8 times with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 1278.0
If we subtract 304 from 336, we get 32.
Append the next digit (9) from the dividend to 32 and continue with: 329 / 38

On to step 6:
38 goes into 329 8 times with a remainder of 25.
The number 8 becomes the next digit in our result. 
Result so far: 12788.0
Subtract 304 from 329 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
38 goes into 250 6 times with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 12788.6
If we subtract 228 from 250, we 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.

Going ahead to step 8:
The number 38 fits into 220 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 12788.65
Subtracting 190 from 220 leaves us 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.

On to step 9:
300 divided by 38 is 7 with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 12788.657
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.

On to step 10:
The number 38 fits into 340 8 times, leaving a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 12788.6578
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 11:
38 can be fit into 360 9 times, resulting in a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 12788.65789
Deduct 342 from 360 and we're left 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.

Moving on to step 12:
38 can be fit into 180 4 times, resulting in a remainder of 28.
The next digit of our result is 4. 
Result so far: 12788.657894
If we take 152 away from 180, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
280 divided by 38 is 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 12788.6578947
Subtract 266 from 280 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
38 goes into 140 3 times with a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 12788.65789473
Deduct 114 from 140 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

In conclusion, the division gives 12788.65789473 with a balance of 2.6e-08.
