125410 divided by 9 
We want to divide 125410 by 9.

Let's proceed to step 1:
If we divide 1 by 9, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 9

Let's proceed to step 2:
12 divided by 9 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 9 from 12 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 9

Going ahead to step 3:
35 divided by 9 is 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 27 from 35 leaves us with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 9

Step 4:
When dividing 84 by 9, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 139.0
The remainder is 3 after subtracting 81 from 84.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 9

Let's proceed to step 5:
The number 9 fits into 31 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 1393.0
Subtract 27 from 31 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 9

Let's proceed to step 6:
9 goes into 40 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 13934.0
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
If we divide 40 by 9, we get 4 and a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 13934.4
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
9 can be fit into 40 4 times, resulting in a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 13934.44
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 13934.44 with a remaining 0.004.
