40251325 divided by 405 
We want to divide 40251325 by 405.

Moving on to step 1:
If we divide 4 by 405, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 405

On to step 2:
405 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Include the next digit (2) from the dividend after 40, then repeat: 402 / 405

On to step 3:
The number 405 fits into 402 0 times, leaving a remainder of 402.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 402 to get 402.
Append the next digit (5) from the dividend to 402 and continue with: 4025 / 405

Moving on to step 4:
405 goes into 4025 9 times with a remainder of 380.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 3645 from 4025 and we're left with 380.
Bring next digit (1) of the dividend behind the 380 and repeat the process: 3801 / 405

Let's proceed to step 5:
3801 divided by 405 is 9 with a remainder of 156.
The next digit of our result is 9. 
Result so far: 99.0
Deduct 3645 from 3801 and we're left with 156.
Include the next digit (3) from the dividend after 156, then repeat: 1563 / 405

On to step 6:
The number 405 fits into 1563 3 times, leaving a remainder of 348.
Put 3 as the next digit of the answer. 
Result so far: 993.0
Subtracting 1215 from 1563 leaves us with 348.
Include the next digit (2) from the dividend after 348, then repeat: 3482 / 405

Let's proceed to step 7:
If we divide 3482 by 405, we get 8 and a remainder of 242.
Write down 8 as next digit of the result. 
Result so far: 9938.0
Subtract 3240 from 3482 to get 242.
Fetch the next digit (5) from the dividend, attach it to 242 and continue: 2425 / 405

Going ahead to step 8:
2425 divided by 405 is 5 with a remainder of 400.
Record the quotient 5 as the next digit in the result. 
Result so far: 99385.0
Subtracting 2025 from 2425 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.

Moving on to step 9:
405 goes into 4000 9 times with a remainder of 355.
The next digit of our result is 9. 
Result so far: 99385.9
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 10:
3550 divided by 405 is 8 with a remainder of 310.
Put 8 as the next digit of the answer. 
Result so far: 99385.98
If we subtract 3240 from 3550, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 11:
3100 divided by 405 is 7 with a remainder of 265.
The number 7 becomes the next digit in our result. 
Result so far: 99385.987
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 12:
405 can be fit into 2650 6 times, resulting in a remainder of 220.
Use 6 as the next digit of our solution. 
Result so far: 99385.9876
If we take 2430 away from 2650, we end up 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 13:
405 goes into 2200 5 times with a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 99385.98765
Deduct 2025 from 2200 and we're left 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.

Moving on to step 14:
When dividing 1750 by 405, we get 4 with a remainder of 130.
Put 4 as the next digit of the answer. 
Result so far: 99385.987654
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.

On to step 15:
If we divide 1300 by 405, we get 3 and a remainder of 85.
The number 3 becomes the next digit in our result. 
Result so far: 99385.9876543
Subtracting 1215 from 1300 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 16:
850 divided by 405 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 99385.98765432
If we subtract 810 from 850, 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.

The final result is 99385.98765432 with a remainder of 4e-08.
