646822 divided by 49 
Our goal is to divide 646822 by 49.

Advancing to step 1:
When dividing 6 by 49, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 49

Step 2:
49 goes into 64 1 times with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 15 after subtracting 49 from 64.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 49

Step 3:
49 can be fit into 156 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 147 away from 156, we end up with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 49

Moving on to step 4:
49 goes into 98 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
Subtract 98 from 98 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 49

Moving on to step 5:
The number 49 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 1320.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 49

Moving on to step 6:
The number 49 fits into 22 0 times, leaving a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 13200.0
Subtracting 0 from 22 leaves us 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.

On to step 7:
If we divide 220 by 49, we get 4 and a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 13200.4
Subtracting 196 from 220 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
49 goes into 240 4 times with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 13200.44
If we take 196 away from 240, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 13200.44 and a remainder of 0.044.
