We're dividing 78073164 by 405 
We're looking to find how many times 405 goes into 78073164.

Let's proceed to step 1:
If we divide 7 by 405, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 405

Advancing to step 2:
The number 405 fits into 78 0 times, leaving a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (0) from the dividend, add it to 78, then carry on: 780 / 405

Advancing to step 3:
When dividing 780 by 405, we get 1 with a remainder of 375.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 405 from 780 leaves us with 375.
Take the next digit (7) from the dividend and append it to 375, then repeat: 3757 / 405

Advancing to step 4:
405 can be fit into 3757 9 times, resulting in a remainder of 112.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 3645 from 3757 and we're left with 112.
Grab the next digit (3) from the dividend, add it to 112, then carry on: 1123 / 405

Moving on to step 5:
405 goes into 1123 2 times with a remainder of 313.
Write down 2 as next digit of the result. 
Result so far: 192.0
The remainder is 313 after subtracting 810 from 1123.
Append the next digit (1) from the dividend to 313 and continue with: 3131 / 405

Let's proceed to step 6:
If we divide 3131 by 405, we get 7 and a remainder of 296.
Write down 7 as next digit of the result. 
Result so far: 1927.0
If we subtract 2835 from 3131, we get 296.
Grab the next digit (6) from the dividend, add it to 296, then carry on: 2966 / 405

Let's proceed to step 7:
If we divide 2966 by 405, we get 7 and a remainder of 131.
Write down 7 as next digit of the result. 
Result so far: 19277.0
If we subtract 2835 from 2966, we get 131.
Bring next digit (4) of the dividend behind the 131 and repeat the process: 1314 / 405

Let's proceed to step 8:
405 can be fit into 1314 3 times, resulting in a remainder of 99.
Use 3 as the next digit of our solution. 
Result so far: 192773.0
If we take 1215 away from 1314, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 9:
405 can be fit into 990 2 times, resulting in a remainder of 180.
The number 2 becomes the next digit in our result. 
Result so far: 192773.2
If we subtract 810 from 990, 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.

Let's proceed to step 10:
1800 divided by 405 is 4 with a remainder of 180.
The number 4 becomes the next digit in our result. 
Result so far: 192773.24
If we take 1620 away from 1800, 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 11:
The number 405 fits into 1800 4 times, leaving a remainder of 180.
Use 4 as the next digit of our solution. 
Result so far: 192773.244
Subtract 1620 from 1800 to 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.

The final result is 192773.244 with a remainder of 0.018.
