49055548 ÷ 405 
Our goal is to divide 49055548 by 405.

Step 1:
When dividing 4 by 405, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 405

Going ahead to step 2:
405 can be fit into 49 0 times, resulting in a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Grab the next digit (0) from the dividend, add it to 49, then carry on: 490 / 405

Going ahead to step 3:
If we divide 490 by 405, we get 1 and a remainder of 85.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 85 after subtracting 405 from 490.
Bring next digit (5) of the dividend behind the 85 and repeat the process: 855 / 405

Moving on to step 4:
When dividing 855 by 405, we get 2 with a remainder of 45.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 45 after subtracting 810 from 855.
Bring next digit (5) of the dividend behind the 45 and repeat the process: 455 / 405

On to step 5:
405 can be fit into 455 1 times, resulting in a remainder of 50.
The next digit of our result is 1. 
Result so far: 121.0
If we take 405 away from 455, we end up with 50.
Fetch the next digit (5) from the dividend, attach it to 50 and continue: 505 / 405

Step 6:
405 can be fit into 505 1 times, resulting in a remainder of 100.
Put 1 as the next digit of the answer. 
Result so far: 1211.0
The remainder is 100 after subtracting 405 from 505.
Include the next digit (4) from the dividend after 100, then repeat: 1004 / 405

Advancing to step 7:
When dividing 1004 by 405, we get 2 with a remainder of 194.
The number 2 becomes the next digit in our result. 
Result so far: 12112.0
The remainder is 194 after subtracting 810 from 1004.
Take the next digit (8) from the dividend and append it to 194, then repeat: 1948 / 405

Moving on to step 8:
1948 divided by 405 is 4 with a remainder of 328.
Write down 4 as next digit of the result. 
Result so far: 121124.0
Deduct 1620 from 1948 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 9:
The number 405 fits into 3280 8 times, leaving a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 121124.8
If we subtract 3240 from 3280, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
405 goes into 400 0 times with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 121124.8
Subtracting 0 from 400 leaves us 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.

Advancing to step 11:
4000 divided by 405 is 9 with a remainder of 355.
The number 9 becomes the next digit in our result. 
Result so far: 121124.809
If we subtract 3645 from 4000, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Advancing to step 12:
405 can be fit into 3550 8 times, resulting in a remainder of 310.
The number 8 becomes the next digit in our result. 
Result so far: 121124.8098
Deduct 3240 from 3550 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 13:
3100 divided by 405 is 7 with a remainder of 265.
Record the quotient 7 as the next digit in the result. 
Result so far: 121124.80987
If we subtract 2835 from 3100, we get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 14:
2650 divided by 405 is 6 with a remainder of 220.
Put 6 as the next digit of the answer. 
Result so far: 121124.809876
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.

Step 15:
405 goes into 2200 5 times with a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 121124.8098765
Subtract 2025 from 2200 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 16:
The number 405 fits into 1750 4 times, leaving a remainder of 130.
Put 4 as the next digit of the answer. 
Result so far: 121124.80987654
If we take 1620 away from 1750, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final outcome is 121124.80987654, with a leftover of 1.3e-07.
