We're dividing 211854 by 49 
We want to figure out the number of times 211854 can be divided by 49.

Step 1:
The number 49 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 49

Going ahead to step 2:
21 divided by 49 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 49

On to step 3:
When dividing 211 by 49, we get 4 with a remainder of 15.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 15 after subtracting 196 from 211.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 49

Moving on to step 4:
If we divide 158 by 49, we get 3 and a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
If we subtract 147 from 158, we get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 49

Let's proceed to step 5:
115 divided by 49 is 2 with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 432.0
If we take 98 away from 115, we end up with 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 49

On to step 6:
When dividing 174 by 49, we get 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 4323.0
If we take 147 away from 174, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
When dividing 270 by 49, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 4323.5
Subtract 245 from 270 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
49 can be fit into 250 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4323.55
Deduct 245 from 250 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 4323.55 and a remainder of 0.005.
