Let's divide 64674004 by 405
Our goal is to divide 64674004 by 405.

Step 1:
405 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 405

Moving on to step 2:
When dividing 64 by 405, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (6) from the dividend, attach it to 64 and continue: 646 / 405

Advancing to step 3:
405 goes into 646 1 times with a remainder of 241.
The next digit of our result is 1. 
Result so far: 1.0
If we take 405 away from 646, we end up with 241.
Include the next digit (7) from the dividend after 241, then repeat: 2417 / 405

Let's proceed to step 4:
405 goes into 2417 5 times with a remainder of 392.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 2025 from 2417, we get 392.
Take the next digit (4) from the dividend and append it to 392, then repeat: 3924 / 405

On to step 5:
The number 405 fits into 3924 9 times, leaving a remainder of 279.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
The remainder is 279 after subtracting 3645 from 3924.
Take the next digit (0) from the dividend and append it to 279, then repeat: 2790 / 405

Step 6:
405 can be fit into 2790 6 times, resulting in a remainder of 360.
The next digit of our result is 6. 
Result so far: 1596.0
The remainder is 360 after subtracting 2430 from 2790.
Bring next digit (0) of the dividend behind the 360 and repeat the process: 3600 / 405

Going ahead to step 7:
405 goes into 3600 8 times with a remainder of 360.
Record the quotient 8 as the next digit in the result. 
Result so far: 15968.0
If we subtract 3240 from 3600, we get 360.
Include the next digit (4) from the dividend after 360, then repeat: 3604 / 405

On to step 8:
If we divide 3604 by 405, we get 8 and a remainder of 364.
Write down 8 as next digit of the result. 
Result so far: 159688.0
Deduct 3240 from 3604 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 9:
405 can be fit into 3640 8 times, resulting in a remainder of 400.
Use 8 as the next digit of our solution. 
Result so far: 159688.8
If we take 3240 away from 3640, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 10:
405 can be fit into 4000 9 times, resulting in a remainder of 355.
The next digit of our result is 9. 
Result so far: 159688.89
Subtracting 3645 from 4000 leaves us with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Step 11:
When dividing 3550 by 405, we get 8 with a remainder of 310.
The number 8 becomes the next digit in our result. 
Result so far: 159688.898
The remainder is 310 after subtracting 3240 from 3550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 12:
The number 405 fits into 3100 7 times, leaving a remainder of 265.
Write down 7 as next digit of the result. 
Result so far: 159688.8987
Subtracting 2835 from 3100 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Advancing to step 13:
If we divide 2650 by 405, we get 6 and a remainder of 220.
The number 6 becomes the next digit in our result. 
Result so far: 159688.89876
Deduct 2430 from 2650 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 14:
If we divide 2200 by 405, we get 5 and a remainder of 175.
The next digit of our result is 5. 
Result so far: 159688.898765
Subtracting 2025 from 2200 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 15:
1750 divided by 405 is 4 with a remainder of 130.
The next digit of our result is 4. 
Result so far: 159688.8987654
The remainder is 130 after subtracting 1620 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 16:
405 goes into 1300 3 times with a remainder of 85.
The next digit of our result is 3. 
Result so far: 159688.89876543
Subtract 1215 from 1300 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Our division results in 159688.89876543 with a remaining 8.5e-08.
