403821 divided by 49 
We're looking to find how many times 49 goes into 403821.

Step 1:
49 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 49

Let's proceed to step 2:
The number 49 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 49

Moving on to step 3:
403 divided by 49 is 8 with a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 392 from 403 and we're left with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 49

Advancing to step 4:
49 goes into 118 2 times with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Subtract 98 from 118 to get 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 49

Step 5:
The number 49 fits into 202 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 824.0
The remainder is 6 after subtracting 196 from 202.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 49

Going ahead to step 6:
If we divide 61 by 49, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 8241.0
Subtract 49 from 61 to 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 7:
The number 49 fits into 120 2 times, leaving a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 8241.2
If we take 98 away from 120, we end up 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.

Advancing to step 8:
The number 49 fits into 220 4 times, leaving a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 8241.24
The remainder is 24 after subtracting 196 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
The number 49 fits into 240 4 times, leaving a remainder of 44.
The next digit of our result is 4. 
Result so far: 8241.244
The remainder is 44 after subtracting 196 from 240.
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 8241.244 and a remainder of 0.0044.
