We divide 136123 by 39
We're looking to find how many times 39 goes into 136123.

Moving on to step 1:
1 divided by 39 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
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 / 39

Let's proceed to step 2:
When dividing 13 by 39, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 39

On to step 3:
39 goes into 136 3 times with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 19 after subtracting 117 from 136.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 39

Step 4:
The number 39 fits into 191 4 times, leaving a remainder of 35.
The next digit of our result is 4. 
Result so far: 34.0
If we subtract 156 from 191, we get 35.
Take the next digit (2) from the dividend and append it to 35, then repeat: 352 / 39

On to step 5:
When dividing 352 by 39, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 349.0
Subtract 351 from 352 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 39

Advancing to step 6:
The number 39 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 3490.0
Subtract 0 from 13 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
When dividing 130 by 39, we get 3 with a remainder of 13.
The next digit of our result is 3. 
Result so far: 3490.3
The remainder is 13 after subtracting 117 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
130 divided by 39 is 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 3490.33
Subtracting 117 from 130 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 3490.33 and a remainder of 0.013.
