63166713 ÷ 405 
We want to figure out the number of times 63166713 can be divided by 405.

On to step 1:
405 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 405

Let's proceed to step 2:
405 goes into 63 0 times with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Take the next digit (1) from the dividend and append it to 63, then repeat: 631 / 405

Advancing to step 3:
If we divide 631 by 405, we get 1 and a remainder of 226.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 405 from 631 leaves us with 226.
Grab the next digit (6) from the dividend, add it to 226, then carry on: 2266 / 405

Advancing to step 4:
405 can be fit into 2266 5 times, resulting in a remainder of 241.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 2025 from 2266 to get 241.
Append the next digit (6) from the dividend to 241 and continue with: 2416 / 405

Advancing to step 5:
2416 divided by 405 is 5 with a remainder of 391.
Record the quotient 5 as the next digit in the result. 
Result so far: 155.0
Subtract 2025 from 2416 to get 391.
Append the next digit (7) from the dividend to 391 and continue with: 3917 / 405

Moving on to step 6:
3917 divided by 405 is 9 with a remainder of 272.
Use 9 as the next digit of our solution. 
Result so far: 1559.0
Deduct 3645 from 3917 and we're left with 272.
Append the next digit (1) from the dividend to 272 and continue with: 2721 / 405

On to step 7:
When dividing 2721 by 405, we get 6 with a remainder of 291.
Put 6 as the next digit of the answer. 
Result so far: 15596.0
Subtracting 2430 from 2721 leaves us with 291.
Include the next digit (3) from the dividend after 291, then repeat: 2913 / 405

On to step 8:
405 goes into 2913 7 times with a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 155967.0
Subtracting 2835 from 2913 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 9:
780 divided by 405 is 1 with a remainder of 375.
Write down 1 as next digit of the result. 
Result so far: 155967.1
If we take 405 away from 780, we end up 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.

Moving on to step 10:
3750 divided by 405 is 9 with a remainder of 105.
The next digit of our result is 9. 
Result so far: 155967.19
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.

Step 11:
1050 divided by 405 is 2 with a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 155967.192
If we subtract 810 from 1050, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 12:
405 can be fit into 2400 5 times, resulting in a remainder of 375.
The next digit of our result is 5. 
Result so far: 155967.1925
Subtract 2025 from 2400 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 13:
405 can be fit into 3750 9 times, resulting in a remainder of 105.
The next digit of our result is 9. 
Result so far: 155967.19259
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.

On to step 14:
405 goes into 1050 2 times with a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 155967.192592
Deduct 810 from 1050 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 15:
The number 405 fits into 2400 5 times, leaving a remainder of 375.
The next digit of our result is 5. 
Result so far: 155967.1925925
Subtracting 2025 from 2400 leaves us 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.

Going ahead to step 16:
405 goes into 3750 9 times with a remainder of 105.
Use 9 as the next digit of our solution. 
Result so far: 155967.19259259
Subtract 3645 from 3750 to 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.

In conclusion, the division gives 155967.19259259 with a balance of 1.05e-07.
