We're dividing 41621 by 38 
The aim is to understand the frequency of 38 in 41621.

Going ahead to step 1:
If we divide 4 by 38, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 38

On to step 2:
If we divide 41 by 38, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 38 from 41, we get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 38

Let's proceed to step 3:
The number 38 fits into 36 0 times, leaving a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 36 to get 36.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 38

Advancing to step 4:
362 divided by 38 is 9 with a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 109.0
Subtracting 342 from 362 leaves us with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 38

Advancing to step 5:
201 divided by 38 is 5 with a remainder of 11.
The next digit of our result is 5. 
Result so far: 1095.0
If we take 190 away from 201, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 6:
When dividing 110 by 38, we get 2 with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 1095.2
Subtract 76 from 110 to get 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.
Use 8 as the next digit of our solution. 
Result so far: 1095.28
If we take 304 away from 340, we end up 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.

Going ahead to step 8:
38 goes into 360 9 times with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 1095.289
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.

Advancing to step 9:
180 divided by 38 is 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 1095.2894
Subtract 152 from 180 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
When dividing 280 by 38, we get 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 1095.28947
Subtracting 266 from 280 leaves us 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.

Advancing to step 11:
If we divide 140 by 38, we get 3 and a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 1095.289473
Subtracting 114 from 140 leaves us 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:
When dividing 260 by 38, we get 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 1095.2894736
Subtract 228 from 260 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
If we divide 320 by 38, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 1095.28947368
If we subtract 304 from 320, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 1095.28947368 with a remaining 1.6e-08.
