Let's divide 405091 by 77
We want to divide 405091 by 77.

Step 1:
77 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 77

Advancing to step 2:
40 divided by 77 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Bring next digit (5) of the dividend behind the 40 and repeat the process: 405 / 77

Going ahead to step 3:
When dividing 405 by 77, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 385 from 405 and we're left with 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 77

Step 4:
77 goes into 200 2 times with a remainder of 46.
The next digit of our result is 2. 
Result so far: 52.0
Subtract 154 from 200 to get 46.
Append the next digit (9) from the dividend to 46 and continue with: 469 / 77

Moving on to step 5:
77 can be fit into 469 6 times, resulting in a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 526.0
If we subtract 462 from 469, we get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 77

Let's proceed to step 6:
When dividing 71 by 77, we get 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 5260.0
Subtract 0 from 71 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 7:
77 can be fit into 710 9 times, resulting in a remainder of 17.
The next digit of our result is 9. 
Result so far: 5260.9
Subtract 693 from 710 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
77 can be fit into 170 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 5260.92
The remainder is 16 after subtracting 154 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
If we divide 160 by 77, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 5260.922
Subtract 154 from 160 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 5260.922 with a balance of 0.0006.
