838358 divided by 3 
The aim is to understand the frequency of 3 in 838358.

Advancing to step 1:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 6 from 8, we get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 3

Advancing to step 2:
The number 3 fits into 23 7 times, leaving a remainder of 2.
The next digit of our result is 7. 
Result so far: 27.0
Subtract 21 from 23 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 3

On to step 3:
When dividing 28 by 3, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 279.0
Subtract 27 from 28 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 3

Advancing to step 4:
When dividing 13 by 3, we get 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 2794.0
Subtracting 12 from 13 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

Let's proceed to step 5:
If we divide 15 by 3, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 27945.0
If we subtract 15 from 15, we get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 3

Advancing to step 6:
The number 3 fits into 8 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 279452.0
Subtracting 6 from 8 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 279452.6
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 279452.66
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 279452.66 with a balance of 0.002.
