We divide 343881 by 38
The aim is to understand the frequency of 38 in 343881.

Step 1:
When dividing 3 by 38, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 38

Advancing to step 2:
If we divide 34 by 38, we get 0 and a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Bring next digit (3) of the dividend behind the 34 and repeat the process: 343 / 38

Going ahead to step 3:
If we divide 343 by 38, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 342 from 343, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 38

Step 4:
18 divided by 38 is 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Deduct 0 from 18 and we're left with 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 38

Moving on to step 5:
38 goes into 188 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 904.0
If we subtract 152 from 188, we get 36.
Grab the next digit (1) from the dividend, add it to 36, then carry on: 361 / 38

Going ahead to step 6:
38 goes into 361 9 times with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 9049.0
If we take 342 away from 361, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
When dividing 190 by 38, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 9049.5
The remainder is 0 after subtracting 190 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 38 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9049.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 38 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9049.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 9049.5 with a balance of 0.0.
