Let's divide 17890 by 38
The aim is to understand the frequency of 38 in 17890.

Moving on to step 1:
The number 38 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 38

Let's proceed to step 2:
17 divided by 38 is 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 38

Let's proceed to step 3:
The number 38 fits into 178 4 times, leaving a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 152 from 178 and we're left with 26.
Bring next digit (9) of the dividend behind the 26 and repeat the process: 269 / 38

Going ahead to step 4:
38 goes into 269 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we subtract 266 from 269, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 38

Let's proceed to step 5:
38 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 470.0
Subtracting 0 from 30 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.

Moving on to step 6:
If we divide 300 by 38, we get 7 and a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 470.7
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 7:
If we divide 340 by 38, we get 8 and a remainder of 36.
The next digit of our result is 8. 
Result so far: 470.78
If we subtract 304 from 340, we get 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 8:
The number 38 fits into 360 9 times, leaving a remainder of 18.
The next digit of our result is 9. 
Result so far: 470.789
If we subtract 342 from 360, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
The number 38 fits into 180 4 times, leaving a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 470.7894
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.

Let's proceed to step 10:
38 goes into 280 7 times with a remainder of 14.
The next digit of our result is 7. 
Result so far: 470.78947
Deduct 266 from 280 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
If we divide 140 by 38, we get 3 and a remainder of 26.
The next digit of our result is 3. 
Result so far: 470.789473
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.

Going ahead to step 12:
38 goes into 260 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 470.7894736
If we take 228 away from 260, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
The number 38 fits into 320 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 470.78947368
Subtracting 304 from 320 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 470.78947368 with a remainder of 1.6e-08.
