Let's divide 25370397 by 405
We're looking to find how many times 405 goes into 25370397.

Step 1:
If we divide 2 by 405, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 405

Let's proceed to step 2:
405 can be fit into 25 0 times, resulting in a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 405

Moving on to step 3:
If we divide 253 by 405, we get 0 and a remainder of 253.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 253 after subtracting 0 from 253.
Append the next digit (7) from the dividend to 253 and continue with: 2537 / 405

Moving on to step 4:
When dividing 2537 by 405, we get 6 with a remainder of 107.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 2430 from 2537 to get 107.
Bring next digit (0) of the dividend behind the 107 and repeat the process: 1070 / 405

Advancing to step 5:
When dividing 1070 by 405, we get 2 with a remainder of 260.
The next digit of our result is 2. 
Result so far: 62.0
Deduct 810 from 1070 and we're left with 260.
Grab the next digit (3) from the dividend, add it to 260, then carry on: 2603 / 405

On to step 6:
405 can be fit into 2603 6 times, resulting in a remainder of 173.
The next digit of our result is 6. 
Result so far: 626.0
If we subtract 2430 from 2603, we get 173.
Include the next digit (9) from the dividend after 173, then repeat: 1739 / 405

Moving on to step 7:
If we divide 1739 by 405, we get 4 and a remainder of 119.
Use 4 as the next digit of our solution. 
Result so far: 6264.0
Subtracting 1620 from 1739 leaves us with 119.
Bring next digit (7) of the dividend behind the 119 and repeat the process: 1197 / 405

On to step 8:
When dividing 1197 by 405, we get 2 with a remainder of 387.
Put 2 as the next digit of the answer. 
Result so far: 62642.0
Deduct 810 from 1197 and we're left with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Step 9:
405 can be fit into 3870 9 times, resulting in a remainder of 225.
Write down 9 as next digit of the result. 
Result so far: 62642.9
If we take 3645 away from 3870, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 10:
The number 405 fits into 2250 5 times, leaving a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 62642.95
Subtract 2025 from 2250 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 11:
When dividing 2250 by 405, we get 5 with a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 62642.955
Deduct 2025 from 2250 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

In conclusion, the division gives 62642.955 with a balance of 0.0225.
