375794 divided by 3 
The aim is to understand the frequency of 3 in 375794.

Let's proceed to step 1:
If we divide 3 by 3, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 0 after subtracting 3 from 3.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 3

Step 2:
3 goes into 7 2 times with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 6 from 7 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 3

Advancing to step 3:
3 can be fit into 15 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
Subtracting 15 from 15 leaves us with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 3

Moving on to step 4:
If we divide 7 by 3, we get 2 and a remainder of 1.
The next digit of our result is 2. 
Result so far: 1252.0
The remainder is 1 after subtracting 6 from 7.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 3

Moving on to step 5:
When dividing 19 by 3, we get 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 12526.0
Subtract 18 from 19 to get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 3

Going ahead to step 6:
14 divided by 3 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 125264.0
If we subtract 12 from 14, we 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.

Going ahead to step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 125264.6
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
3 goes into 20 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 125264.66
If we subtract 18 from 20, we 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.

Our division results in 125264.66 with a remaining 0.002.
