66477102 ÷ 405 
We're looking to find how many times 405 goes into 66477102.

Advancing to step 1:
405 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 405

Moving on to step 2:
66 divided by 405 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 405

Step 3:
664 divided by 405 is 1 with a remainder of 259.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 259 after subtracting 405 from 664.
Grab the next digit (7) from the dividend, add it to 259, then carry on: 2597 / 405

On to step 4:
405 can be fit into 2597 6 times, resulting in a remainder of 167.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 2430 from 2597 and we're left with 167.
Grab the next digit (7) from the dividend, add it to 167, then carry on: 1677 / 405

Step 5:
405 goes into 1677 4 times with a remainder of 57.
Write down 4 as next digit of the result. 
Result so far: 164.0
Subtracting 1620 from 1677 leaves us with 57.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 405

Step 6:
The number 405 fits into 571 1 times, leaving a remainder of 166.
The next digit of our result is 1. 
Result so far: 1641.0
Deduct 405 from 571 and we're left with 166.
Bring next digit (0) of the dividend behind the 166 and repeat the process: 1660 / 405

Step 7:
405 can be fit into 1660 4 times, resulting in a remainder of 40.
The next digit of our result is 4. 
Result so far: 16414.0
Deduct 1620 from 1660 and we're left with 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 405

Step 8:
405 goes into 402 0 times with a remainder of 402.
Use 0 as the next digit of our solution. 
Result so far: 164140.0
Subtract 0 from 402 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Advancing to step 9:
4020 divided by 405 is 9 with a remainder of 375.
The number 9 becomes the next digit in our result. 
Result so far: 164140.9
Deduct 3645 from 4020 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 10:
The number 405 fits into 3750 9 times, leaving a remainder of 105.
Record the quotient 9 as the next digit in the result. 
Result so far: 164140.99
If we subtract 3645 from 3750, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The quotient of the division is 164140.99, and the remainder is 0.105.
