We look at the division of 254821 by 4 
Let's see how many times 4 fits into 254821.

Step 1:
The number 4 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 4

On to step 2:
4 can be fit into 25 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 24 from 25 leaves us with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 4

Step 3:
When dividing 14 by 4, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Subtract 12 from 14 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 4

Moving on to step 4:
When dividing 28 by 4, we get 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 637.0
Deduct 28 from 28 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 4

Moving on to step 5:
If we divide 2 by 4, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 6370.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 4

Advancing to step 6:
The number 4 fits into 21 5 times, leaving a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 63705.0
If we subtract 20 from 21, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
4 goes into 10 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 63705.2
If we subtract 8 from 10, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 63705.25
Subtract 20 from 20 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 63705.25
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
If we divide 0 by 4, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 63705.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 63705.25, with a leftover of 0.0.
