Going ahead to step 1:
The number 21 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 21

Moving on to step 2:
When dividing 41 by 21, we get 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 21 from 41 leaves us with 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 21

Let's proceed to step 3:
The number 21 fits into 208 9 times, leaving a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 189 from 208 leaves us with 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 21

Moving on to step 4:
When dividing 194 by 21, we get 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 199.0
Subtracting 189 from 194 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 21

On to step 5:
If we divide 53 by 21, we get 2 and a remainder of 11.
The next digit of our result is 2. 
Result so far: 1992.0
If we subtract 42 from 53, we get 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 21

On to step 6:
The number 21 fits into 115 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 19925.0

Append the next digit (9) from the dividend to 10 and continue with: 109 / 21

Step 7:
The number 21 fits into 109 5 times, leaving a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 199255.0
If we subtract 105 from 109, we get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 21

On to step 8:
When dividing 49 by 21, we get 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 1992552.0
Subtracting 42 from 49 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
If we divide 70 by 21, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 1992552.3
Subtract 63 from 70 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
If we divide 70 by 21, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 1992552.33
Subtracting 63 from 70 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.
