621821 divided by 49 
Our goal is to divide 621821 by 49.

Going ahead to step 1:
6 divided by 49 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 49

Step 2:
The number 49 fits into 62 1 times, leaving a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 49 away from 62, we end up with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 49

Let's proceed to step 3:
131 divided by 49 is 2 with a remainder of 33.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 98 from 131 leaves us with 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 49

Advancing to step 4:
If we divide 338 by 49, we get 6 and a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 126.0
Subtract 294 from 338 to get 44.
Append the next digit (2) from the dividend to 44 and continue with: 442 / 49

On to step 5:
49 goes into 442 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 1269.0
The remainder is 1 after subtracting 441 from 442.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 49

On to step 6:
11 divided by 49 is 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 12690.0
If we take 0 away from 11, we end up 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.

Advancing to step 7:
49 can be fit into 110 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 12690.2
Deduct 98 from 110 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
49 goes into 120 2 times with a remainder of 22.
The next digit of our result is 2. 
Result so far: 12690.22
Deduct 98 from 120 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 12690.22 with a remaining 0.022.
