We look at the division of 509642 by 49 
We're looking to find how many times 49 goes into 509642.

Let's proceed to step 1:
When dividing 5 by 49, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 49

Going ahead to step 2:
49 goes into 50 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 49 from 50, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 49

Moving on to step 3:
When dividing 19 by 49, we get 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 19 leaves us with 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 49

Going ahead to step 4:
If we divide 196 by 49, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 104.0
Subtract 196 from 196 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 49

Step 5:
The number 49 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 1040.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 49

Let's proceed to step 6:
The number 49 fits into 42 0 times, leaving a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 10400.0
If we subtract 0 from 42, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 7:
If we divide 420 by 49, we get 8 and a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 10400.8
Subtracting 392 from 420 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
When dividing 280 by 49, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 10400.85
If we subtract 245 from 280, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
When dividing 350 by 49, we get 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 10400.857
If we subtract 343 from 350, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
49 goes into 70 1 times with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 10400.8571
The remainder is 21 after subtracting 49 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 11:
If we divide 210 by 49, we get 4 and a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 10400.85714
The remainder is 14 after subtracting 196 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
When dividing 140 by 49, we get 2 with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 10400.857142
If we subtract 98 from 140, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 13:
49 goes into 420 8 times with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 10400.8571428
The remainder is 28 after subtracting 392 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 14:
If we divide 280 by 49, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 10400.85714285
If we take 245 away from 280, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 10400.85714285, with a leftover of 3.5e-08.
