We're dividing 134123 by 3 
We want to figure out the number of times 134123 can be divided by 3.

Moving on to step 1:
If we divide 1 by 3, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 3

Moving on to step 2:
When dividing 13 by 3, we get 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 1 after subtracting 12 from 13.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 3

Step 3:
When dividing 14 by 3, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
The remainder is 2 after subtracting 12 from 14.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 3

Let's proceed to step 4:
3 can be fit into 21 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 447.0
Deduct 21 from 21 and we're left with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 3

Going ahead to step 5:
3 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 4470.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 3

Let's proceed to step 6:
When dividing 23 by 3, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 44707.0
Subtract 21 from 23 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.

Step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 44707.6
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.

Let's proceed to step 8:
3 goes into 20 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 44707.66
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.

In conclusion, the division gives 44707.66 with a balance of 0.002.
