Let's divide 54836664 by 405
Let's see how many times 405 fits into 54836664.

On to step 1:
The number 405 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 405

Step 2:
The number 405 fits into 54 0 times, leaving a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Include the next digit (8) from the dividend after 54, then repeat: 548 / 405

Advancing to step 3:
The number 405 fits into 548 1 times, leaving a remainder of 143.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 405 from 548, we get 143.
Take the next digit (3) from the dividend and append it to 143, then repeat: 1433 / 405

On to step 4:
405 can be fit into 1433 3 times, resulting in a remainder of 218.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 1215 from 1433, we get 218.
Include the next digit (6) from the dividend after 218, then repeat: 2186 / 405

Step 5:
The number 405 fits into 2186 5 times, leaving a remainder of 161.
Write down 5 as next digit of the result. 
Result so far: 135.0
Deduct 2025 from 2186 and we're left with 161.
Append the next digit (6) from the dividend to 161 and continue with: 1616 / 405

Step 6:
When dividing 1616 by 405, we get 3 with a remainder of 401.
Write down 3 as next digit of the result. 
Result so far: 1353.0
Subtract 1215 from 1616 to get 401.
Bring next digit (6) of the dividend behind the 401 and repeat the process: 4016 / 405

Moving on to step 7:
The number 405 fits into 4016 9 times, leaving a remainder of 371.
Put 9 as the next digit of the answer. 
Result so far: 13539.0
If we take 3645 away from 4016, we end up with 371.
Grab the next digit (4) from the dividend, add it to 371, then carry on: 3714 / 405

On to step 8:
3714 divided by 405 is 9 with a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 135399.0
Subtract 3645 from 3714 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 9:
The number 405 fits into 690 1 times, leaving a remainder of 285.
The number 1 becomes the next digit in our result. 
Result so far: 135399.1
The remainder is 285 after subtracting 405 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 10:
When dividing 2850 by 405, we get 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 135399.17
If we subtract 2835 from 2850, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
405 goes into 150 0 times with a remainder of 150.
The next digit of our result is 0. 
Result so far: 135399.17
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 12:
When dividing 1500 by 405, we get 3 with a remainder of 285.
The next digit of our result is 3. 
Result so far: 135399.1703
Subtracting 1215 from 1500 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 13:
When dividing 2850 by 405, we get 7 with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 135399.17037
The remainder is 15 after subtracting 2835 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
405 goes into 150 0 times with a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 135399.17037
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 15:
The number 405 fits into 1500 3 times, leaving a remainder of 285.
Record the quotient 3 as the next digit in the result. 
Result so far: 135399.1703703
The remainder is 285 after subtracting 1215 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 16:
405 goes into 2850 7 times with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 135399.17037037
If we subtract 2835 from 2850, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 135399.17037037 with a remaining 1.5e-08.
