126009 divided by 49 
We're looking to find how many times 49 goes into 126009.

Advancing to step 1:
If we divide 1 by 49, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 49

Step 2:
49 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 49

On to step 3:
126 divided by 49 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 98 from 126 and we're left with 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 49

Advancing to step 4:
When dividing 280 by 49, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 245 away from 280, we end up with 35.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 49

Let's proceed to step 5:
If we divide 350 by 49, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 257.0
If we subtract 343 from 350, we get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 49

On to step 6:
79 divided by 49 is 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 2571.0
Subtracting 49 from 79 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
49 can be fit into 300 6 times, resulting in a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 2571.6
If we take 294 away from 300, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
If we divide 60 by 49, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 2571.61
Deduct 49 from 60 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
49 can be fit into 110 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 2571.612
If we subtract 98 from 110, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
If we divide 120 by 49, we get 2 and a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 2571.6122
The remainder is 22 after subtracting 98 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 2571.6122 with a remainder of 0.00022.
