We're dividing 126009 by 50 
We want to figure out the number of times 126009 can be divided by 50.

Moving on to step 1:
If we divide 1 by 50, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 50

Advancing to step 2:
When dividing 12 by 50, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 50

On to step 3:
50 goes into 126 2 times with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 100 away from 126, we end up with 26.
Fetch the next digit (0) from the dividend, attach it to 26 and continue: 260 / 50

Moving on to step 4:
When dividing 260 by 50, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we subtract 250 from 260, we get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 50

Let's proceed to step 5:
50 can be fit into 100 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 252.0
Deduct 100 from 100 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 50

Going ahead to step 6:
If we divide 9 by 50, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 2520.0
Subtract 0 from 9 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
50 can be fit into 90 1 times, resulting in a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 2520.1
If we take 50 away from 90, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
When dividing 400 by 50, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 2520.18
If we subtract 400 from 400, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
50 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2520.18
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
50 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2520.18
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 2520.18 with a remainder of 0.0.
