54027950 ÷ 405 
Let's see how many times 405 fits into 54027950.

Let's proceed to step 1:
405 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 405

Moving on to step 2:
When dividing 54 by 405, we get 0 with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Bring next digit (0) of the dividend behind the 54 and repeat the process: 540 / 405

Step 3:
The number 405 fits into 540 1 times, leaving a remainder of 135.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 405 from 540 leaves us with 135.
Bring next digit (2) of the dividend behind the 135 and repeat the process: 1352 / 405

On to step 4:
405 goes into 1352 3 times with a remainder of 137.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 1215 from 1352, we get 137.
Include the next digit (7) from the dividend after 137, then repeat: 1377 / 405

Step 5:
The number 405 fits into 1377 3 times, leaving a remainder of 162.
Write down 3 as next digit of the result. 
Result so far: 133.0
Deduct 1215 from 1377 and we're left with 162.
Bring next digit (9) of the dividend behind the 162 and repeat the process: 1629 / 405

On to step 6:
405 can be fit into 1629 4 times, resulting in a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 1334.0
Subtract 1620 from 1629 to get 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 405

Advancing to step 7:
If we divide 95 by 405, we get 0 and a remainder of 95.
The number 0 becomes the next digit in our result. 
Result so far: 13340.0
Subtract 0 from 95 to get 95.
Bring next digit (0) of the dividend behind the 95 and repeat the process: 950 / 405

Step 8:
405 goes into 950 2 times with a remainder of 140.
The number 2 becomes the next digit in our result. 
Result so far: 133402.0
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 9:
405 can be fit into 1400 3 times, resulting in a remainder of 185.
Write down 3 as next digit of the result. 
Result so far: 133402.3
If we subtract 1215 from 1400, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 10:
405 goes into 1850 4 times with a remainder of 230.
Use 4 as the next digit of our solution. 
Result so far: 133402.34
Subtract 1620 from 1850 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 11:
2300 divided by 405 is 5 with a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 133402.345
The remainder is 275 after subtracting 2025 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 12:
2750 divided by 405 is 6 with a remainder of 320.
Put 6 as the next digit of the answer. 
Result so far: 133402.3456
Subtract 2430 from 2750 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 13:
405 can be fit into 3200 7 times, resulting in a remainder of 365.
Record the quotient 7 as the next digit in the result. 
Result so far: 133402.34567
Subtract 2835 from 3200 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Moving on to step 14:
If we divide 3650 by 405, we get 9 and a remainder of 5.
The next digit of our result is 9. 
Result so far: 133402.345679
Subtract 3645 from 3650 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 15:
50 divided by 405 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 133402.345679
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.

Let's proceed to step 16:
The number 405 fits into 500 1 times, leaving a remainder of 95.
The number 1 becomes the next digit in our result. 
Result so far: 133402.34567901
Deduct 405 from 500 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

The quotient of the division is 133402.34567901, and the remainder is 9.5e-08.
