405867 ÷ 55 
Our goal is to divide 405867 by 55.

Going ahead to step 1:
When dividing 4 by 55, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 55

Let's proceed to step 2:
40 divided by 55 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 55

Advancing to step 3:
55 can be fit into 405 7 times, resulting in a remainder of 20.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 385 from 405 and we're left with 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 55

Step 4:
55 can be fit into 208 3 times, resulting in a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Deduct 165 from 208 and we're left with 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 55

Advancing to step 5:
55 can be fit into 436 7 times, resulting in a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 737.0
If we take 385 away from 436, we end up with 51.
Append the next digit (7) from the dividend to 51 and continue with: 517 / 55

Going ahead to step 6:
55 goes into 517 9 times with a remainder of 22.
The next digit of our result is 9. 
Result so far: 7379.0
Subtract 495 from 517 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
If we divide 220 by 55, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 7379.4
The remainder is 0 after subtracting 220 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 55, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7379.4
Deduct 0 from 0 and we're left 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.

Advancing to step 9:
The number 55 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7379.4
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.

The final result is 7379.4 with a remainder of 0.0.
