Let's divide 398921 by 49
Our goal is to divide 398921 by 49.

Let's proceed to step 1:
49 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 49

Going ahead to step 2:
If we divide 39 by 49, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 49

On to step 3:
The number 49 fits into 398 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 392 from 398, we get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 49

Let's proceed to step 4:
If we divide 69 by 49, we get 1 and a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
If we take 49 away from 69, we end up with 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 49

Going ahead to step 5:
The number 49 fits into 202 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 814.0
If we subtract 196 from 202, we get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 49

On to step 6:
49 can be fit into 61 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 8141.0
Subtracting 49 from 61 leaves us 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.

Step 7:
49 goes into 120 2 times with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 8141.2
The remainder is 22 after subtracting 98 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
49 goes into 220 4 times with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 8141.24
Deduct 196 from 220 and we're left 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.

Moving on to step 9:
49 can be fit into 240 4 times, resulting in a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 8141.244
Subtracting 196 from 240 leaves us 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.

The quotient of the division is 8141.244, and the remainder is 0.0044.
