We divide 17484557 by 405
We want to divide 17484557 by 405.

Let's proceed to step 1:
405 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 405

Advancing to step 2:
405 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 405

Step 3:
If we divide 174 by 405, we get 0 and a remainder of 174.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 174 and we're left with 174.
Include the next digit (8) from the dividend after 174, then repeat: 1748 / 405

Moving on to step 4:
405 can be fit into 1748 4 times, resulting in a remainder of 128.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 1620 from 1748 leaves us with 128.
Grab the next digit (4) from the dividend, add it to 128, then carry on: 1284 / 405

Advancing to step 5:
405 goes into 1284 3 times with a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
If we take 1215 away from 1284, we end up with 69.
Append the next digit (5) from the dividend to 69 and continue with: 695 / 405

On to step 6:
When dividing 695 by 405, we get 1 with a remainder of 290.
The number 1 becomes the next digit in our result. 
Result so far: 431.0
If we subtract 405 from 695, we get 290.
Append the next digit (5) from the dividend to 290 and continue with: 2905 / 405

Going ahead to step 7:
When dividing 2905 by 405, we get 7 with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 4317.0
Deduct 2835 from 2905 and we're left with 70.
Grab the next digit (7) from the dividend, add it to 70, then carry on: 707 / 405

On to step 8:
If we divide 707 by 405, we get 1 and a remainder of 302.
The next digit of our result is 1. 
Result so far: 43171.0
If we subtract 405 from 707, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Moving on to step 9:
3020 divided by 405 is 7 with a remainder of 185.
The next digit of our result is 7. 
Result so far: 43171.7
The remainder is 185 after subtracting 2835 from 3020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 10:
405 goes into 1850 4 times with a remainder of 230.
Put 4 as the next digit of the answer. 
Result so far: 43171.74
The remainder is 230 after subtracting 1620 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 11:
If we divide 2300 by 405, we get 5 and a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 43171.745
Subtract 2025 from 2300 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 12:
If we divide 2750 by 405, we get 6 and a remainder of 320.
The number 6 becomes the next digit in our result. 
Result so far: 43171.7456
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.

Going ahead to step 13:
3200 divided by 405 is 7 with a remainder of 365.
Use 7 as the next digit of our solution. 
Result so far: 43171.74567
If we subtract 2835 from 3200, we 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:
3650 divided by 405 is 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 43171.745679
If we subtract 3645 from 3650, we 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.

Advancing to step 15:
The number 405 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 43171.745679
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 16:
405 goes into 500 1 times with a remainder of 95.
Use 1 as the next digit of our solution. 
Result so far: 43171.74567901
If we take 405 away from 500, we end up 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 final result is 43171.74567901 with a remainder of 9.5e-08.
