We look at the division of 16444831 by 405 
Let's see how many times 405 fits into 16444831.

Going ahead to step 1:
The number 405 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 405

On to step 2:
405 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 405

Going ahead to step 3:
When dividing 164 by 405, we get 0 with a remainder of 164.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 164 and we're left with 164.
Fetch the next digit (4) from the dividend, attach it to 164 and continue: 1644 / 405

Step 4:
405 goes into 1644 4 times with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 1620 from 1644 and we're left with 24.
Bring next digit (4) of the dividend behind the 24 and repeat the process: 244 / 405

Step 5:
If we divide 244 by 405, we get 0 and a remainder of 244.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Subtracting 0 from 244 leaves us with 244.
Grab the next digit (8) from the dividend, add it to 244, then carry on: 2448 / 405

Moving on to step 6:
The number 405 fits into 2448 6 times, leaving a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 406.0
If we take 2430 away from 2448, we end up with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 405

Step 7:
When dividing 183 by 405, we get 0 with a remainder of 183.
The next digit of our result is 0. 
Result so far: 4060.0
If we subtract 0 from 183, we get 183.
Append the next digit (1) from the dividend to 183 and continue with: 1831 / 405

Going ahead to step 8:
405 can be fit into 1831 4 times, resulting in a remainder of 211.
Record the quotient 4 as the next digit in the result. 
Result so far: 40604.0
If we subtract 1620 from 1831, we get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Let's proceed to step 9:
405 goes into 2110 5 times with a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 40604.5
Subtract 2025 from 2110 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 10:
405 can be fit into 850 2 times, resulting in a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 40604.52
Subtract 810 from 850 to 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.

Going ahead to step 11:
405 can be fit into 400 0 times, resulting in a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 40604.52
Deduct 0 from 400 and we're left 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.

Step 12:
405 can be fit into 4000 9 times, resulting in a remainder of 355.
Use 9 as the next digit of our solution. 
Result so far: 40604.5209
If we take 3645 away from 4000, we end up with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Moving on to step 13:
3550 divided by 405 is 8 with a remainder of 310.
Put 8 as the next digit of the answer. 
Result so far: 40604.52098
If we take 3240 away from 3550, we end up 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.

On to step 14:
The number 405 fits into 3100 7 times, leaving a remainder of 265.
Put 7 as the next digit of the answer. 
Result so far: 40604.520987
Subtract 2835 from 3100 to 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.

Advancing to step 15:
When dividing 2650 by 405, we get 6 with a remainder of 220.
Write down 6 as next digit of the result. 
Result so far: 40604.5209876
The remainder is 220 after subtracting 2430 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 16:
2200 divided by 405 is 5 with a remainder of 175.
The next digit of our result is 5. 
Result so far: 40604.52098765
If we take 2025 away from 2200, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The final result is 40604.52098765 with a remainder of 1.75e-07.
