We're dividing 85557159 by 405 
We want to figure out the number of times 85557159 can be divided by 405.

Let's proceed to step 1:
When dividing 8 by 405, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 405

Going ahead to step 2:
When dividing 85 by 405, we get 0 with a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Bring next digit (5) of the dividend behind the 85 and repeat the process: 855 / 405

Moving on to step 3:
855 divided by 405 is 2 with a remainder of 45.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 810 from 855 leaves us with 45.
Include the next digit (5) from the dividend after 45, then repeat: 455 / 405

Step 4:
405 can be fit into 455 1 times, resulting in a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 21.0
Deduct 405 from 455 and we're left with 50.
Bring next digit (7) of the dividend behind the 50 and repeat the process: 507 / 405

On to step 5:
The number 405 fits into 507 1 times, leaving a remainder of 102.
Put 1 as the next digit of the answer. 
Result so far: 211.0
Subtracting 405 from 507 leaves us with 102.
Bring next digit (1) of the dividend behind the 102 and repeat the process: 1021 / 405

Advancing to step 6:
If we divide 1021 by 405, we get 2 and a remainder of 211.
The next digit of our result is 2. 
Result so far: 2112.0
If we take 810 away from 1021, we end up with 211.
Append the next digit (5) from the dividend to 211 and continue with: 2115 / 405

Let's proceed to step 7:
If we divide 2115 by 405, we get 5 and a remainder of 90.
The next digit of our result is 5. 
Result so far: 21125.0
Subtract 2025 from 2115 to get 90.
Include the next digit (9) from the dividend after 90, then repeat: 909 / 405

Let's proceed to step 8:
When dividing 909 by 405, we get 2 with a remainder of 99.
Record the quotient 2 as the next digit in the result. 
Result so far: 211252.0
The remainder is 99 after subtracting 810 from 909.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 9:
The number 405 fits into 990 2 times, leaving a remainder of 180.
The next digit of our result is 2. 
Result so far: 211252.2
If we take 810 away from 990, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 10:
When dividing 1800 by 405, we get 4 with a remainder of 180.
The number 4 becomes the next digit in our result. 
Result so far: 211252.24
The remainder is 180 after subtracting 1620 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 11:
405 can be fit into 1800 4 times, resulting in a remainder of 180.
Use 4 as the next digit of our solution. 
Result so far: 211252.244
If we subtract 1620 from 1800, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Our division results in 211252.244 with a remaining 0.018.
