We look at the division of 40812384 by 405 
We're looking to find how many times 405 goes into 40812384.

Moving on to 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
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 405

Moving on to step 2:
The number 405 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 405

Moving on to step 3:
405 can be fit into 408 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we take 405 away from 408, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 405

On to step 4:
405 can be fit into 31 0 times, resulting in a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 405

Let's proceed to step 5:
When dividing 312 by 405, we get 0 with a remainder of 312.
Write down 0 as next digit of the result. 
Result so far: 100.0
Deduct 0 from 312 and we're left with 312.
Take the next digit (3) from the dividend and append it to 312, then repeat: 3123 / 405

On to step 6:
405 goes into 3123 7 times with a remainder of 288.
Put 7 as the next digit of the answer. 
Result so far: 1007.0
Deduct 2835 from 3123 and we're left with 288.
Fetch the next digit (8) from the dividend, attach it to 288 and continue: 2888 / 405

Going ahead to step 7:
When dividing 2888 by 405, we get 7 with a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 10077.0
If we subtract 2835 from 2888, we get 53.
Bring next digit (4) of the dividend behind the 53 and repeat the process: 534 / 405

Let's proceed to step 8:
534 divided by 405 is 1 with a remainder of 129.
The next digit of our result is 1. 
Result so far: 100771.0
Subtract 405 from 534 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Going ahead to step 9:
1290 divided by 405 is 3 with a remainder of 75.
Use 3 as the next digit of our solution. 
Result so far: 100771.3
Subtract 1215 from 1290 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 10:
When dividing 750 by 405, we get 1 with a remainder of 345.
The next digit of our result is 1. 
Result so far: 100771.31
If we subtract 405 from 750, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Step 11:
If we divide 3450 by 405, we get 8 and a remainder of 210.
Put 8 as the next digit of the answer. 
Result so far: 100771.318
Subtract 3240 from 3450 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 12:
2100 divided by 405 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 100771.3185
If we take 2025 away from 2100, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 13:
405 can be fit into 750 1 times, resulting in a remainder of 345.
The next digit of our result is 1. 
Result so far: 100771.31851
Subtracting 405 from 750 leaves us with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Moving on to step 14:
405 goes into 3450 8 times with a remainder of 210.
The number 8 becomes the next digit in our result. 
Result so far: 100771.318518
Subtract 3240 from 3450 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 15:
2100 divided by 405 is 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 100771.3185185
If we take 2025 away from 2100, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 16:
When dividing 750 by 405, we get 1 with a remainder of 345.
The number 1 becomes the next digit in our result. 
Result so far: 100771.31851851
If we subtract 405 from 750, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

After the division, we end up with 100771.31851851 and a remainder of 3.45e-07.
