We're dividing 518921 by 49 
Let's see how many times 49 fits into 518921.

Step 1:
If we divide 5 by 49, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 49

Going ahead to step 2:
When dividing 51 by 49, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 49 from 51 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 49

Moving on to step 3:
49 goes into 28 0 times with a remainder of 28.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 28, we get 28.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 49

Moving on to step 4:
If we divide 289 by 49, we get 5 and a remainder of 44.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
If we subtract 245 from 289, we get 44.
Fetch the next digit (2) from the dividend, attach it to 44 and continue: 442 / 49

Step 5:
442 divided by 49 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 1059.0
Subtract 441 from 442 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 49

Step 6:
If we divide 11 by 49, we get 0 and a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 10590.0
The remainder is 11 after subtracting 0 from 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 7:
49 goes into 110 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 10590.2
The remainder is 12 after subtracting 98 from 110.
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 8:
120 divided by 49 is 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 10590.22
If we subtract 98 from 120, we get 22.
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 outcome is 10590.22, with a leftover of 0.022.
