Let's divide 77641484 by 405
We're looking to find how many times 405 goes into 77641484.

Advancing to step 1:
If we divide 7 by 405, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 405

Let's proceed to step 2:
The number 405 fits into 77 0 times, leaving a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Include the next digit (6) from the dividend after 77, then repeat: 776 / 405

Going ahead to step 3:
776 divided by 405 is 1 with a remainder of 371.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 405 from 776, we get 371.
Include the next digit (4) from the dividend after 371, then repeat: 3714 / 405

On to step 4:
3714 divided by 405 is 9 with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 3645 from 3714 and we're left with 69.
Append the next digit (1) from the dividend to 69 and continue with: 691 / 405

On to step 5:
691 divided by 405 is 1 with a remainder of 286.
Write down 1 as next digit of the result. 
Result so far: 191.0
If we take 405 away from 691, we end up with 286.
Fetch the next digit (4) from the dividend, attach it to 286 and continue: 2864 / 405

Moving on to step 6:
When dividing 2864 by 405, we get 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 1917.0
Subtracting 2835 from 2864 leaves us with 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 405

Going ahead to step 7:
405 can be fit into 298 0 times, resulting in a remainder of 298.
Record the quotient 0 as the next digit in the result. 
Result so far: 19170.0
If we subtract 0 from 298, we get 298.
Include the next digit (4) from the dividend after 298, then repeat: 2984 / 405

Step 8:
2984 divided by 405 is 7 with a remainder of 149.
Write down 7 as next digit of the result. 
Result so far: 191707.0
The remainder is 149 after subtracting 2835 from 2984.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Let's proceed to step 9:
When dividing 1490 by 405, we get 3 with a remainder of 275.
Write down 3 as next digit of the result. 
Result so far: 191707.3
If we subtract 1215 from 1490, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 10:
405 can be fit into 2750 6 times, resulting in a remainder of 320.
Put 6 as the next digit of the answer. 
Result so far: 191707.36
If we take 2430 away from 2750, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 11:
The number 405 fits into 3200 7 times, leaving a remainder of 365.
Put 7 as the next digit of the answer. 
Result so far: 191707.367
Subtracting 2835 from 3200 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Advancing to step 12:
405 can be fit into 3650 9 times, resulting in a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 191707.3679
Deduct 3645 from 3650 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
If we divide 50 by 405, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 191707.3679
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
When dividing 500 by 405, we get 1 with a remainder of 95.
The next digit of our result is 1. 
Result so far: 191707.367901
If we subtract 405 from 500, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 15:
If we divide 950 by 405, we get 2 and a remainder of 140.
Put 2 as the next digit of the answer. 
Result so far: 191707.3679012
Subtracting 810 from 950 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 16:
1400 divided by 405 is 3 with a remainder of 185.
The next digit of our result is 3. 
Result so far: 191707.36790123
The remainder is 185 after subtracting 1215 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

After the division, we end up with 191707.36790123 and a remainder of 1.85e-07.
