Moving on to step 1:
405 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 405

Advancing to step 2:
405 goes into 82 0 times with a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 82, we get 82.
Take the next digit (1) from the dividend and append it to 82, then repeat: 821 / 405

On to step 3:
405 can be fit into 821 2 times, resulting in a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 810 from 821 to get 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 405

Step 4:
The number 405 fits into 119 0 times, leaving a remainder of 119.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 119 leaves us with 119.
Append the next digit (1) from the dividend to 119 and continue with: 1191 / 405

Let's proceed to step 5:
When dividing 1191 by 405, we get 2 with a remainder of 381.
The number 2 becomes the next digit in our result. 
Result so far: 202.0
If we take 810 away from 1191, we end up with 381.
Take the next digit (4) from the dividend and append it to 381, then repeat: 3814 / 405

Let's proceed to step 6:
405 goes into 3814 9 times with a remainder of 169.
The next digit of our result is 9. 
Result so far: 2029.0
If we take 3645 away from 3814, we end up with 169.
Include the next digit (5) from the dividend after 169, then repeat: 1695 / 405

Moving on to step 7:
405 goes into 1695 4 times with a remainder of 75.
Put 4 as the next digit of the answer. 
Result so far: 20294.0
If we take 1620 away from 1695, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 8:
405 can be fit into 750 1 times, resulting in a remainder of 345.
Put 1 as the next digit of the answer. 
Result so far: 20294.1
The remainder is 345 after subtracting 405 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

On to step 9:
3450 divided by 405 is 8 with a remainder of 210.
The number 8 becomes the next digit in our result. 
Result so far: 20294.18
Subtract 3240 from 3450 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 10:
2100 divided by 405 is 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 20294.185
If we take 2025 away from 2100, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 11:
If we divide 750 by 405, we get 1 and a remainder of 345.
The number 1 becomes the next digit in our result. 
Result so far: 20294.1851
Deduct 405 from 750 and we're left with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

On to step 12:
3450 divided by 405 is 8 with a remainder of 210.
The number 8 becomes the next digit in our result. 
Result so far: 20294.18518
If we take 3240 away from 3450, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 13:
When dividing 2100 by 405, we get 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 20294.185185
Subtract 2025 from 2100 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 14:
750 divided by 405 is 1 with a remainder of 345.
Use 1 as the next digit of our solution. 
Result so far: 20294.1851851
If we take 405 away from 750, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Moving on to step 15:
405 can be fit into 3450 8 times, resulting in a remainder of 210.
The number 8 becomes the next digit in our result. 
Result so far: 20294.18518518
Subtracting 3240 from 3450 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Our division results in 20294.18518518 with a remaining 2.1e-07.
