3212465 ÷ 405 
Let's see how many times 405 fits into 3212465.

Going ahead to step 1:
3 divided by 405 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 405

Advancing to step 2:
When dividing 32 by 405, we get 0 with a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Append the next digit (1) from the dividend to 32 and continue with: 321 / 405

Moving on to step 3:
321 divided by 405 is 0 with a remainder of 321.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 321, we end up with 321.
Take the next digit (2) from the dividend and append it to 321, then repeat: 3212 / 405

Going ahead to step 4:
405 can be fit into 3212 7 times, resulting in a remainder of 377.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 2835 from 3212 to get 377.
Include the next digit (4) from the dividend after 377, then repeat: 3774 / 405

Step 5:
3774 divided by 405 is 9 with a remainder of 129.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Subtracting 3645 from 3774 leaves us with 129.
Include the next digit (6) from the dividend after 129, then repeat: 1296 / 405

Advancing to step 6:
1296 divided by 405 is 3 with a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 793.0
Deduct 1215 from 1296 and we're left with 81.
Fetch the next digit (5) from the dividend, attach it to 81 and continue: 815 / 405

Going ahead to step 7:
815 divided by 405 is 2 with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 7932.0
If we take 810 away from 815, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
The number 405 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 7932.0
If we take 0 away from 50, we end up 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.

Let's proceed to step 9:
500 divided by 405 is 1 with a remainder of 95.
Record the quotient 1 as the next digit in the result. 
Result so far: 7932.01
Subtracting 405 from 500 leaves us 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.

Let's proceed to step 10:
If we divide 950 by 405, we get 2 and a remainder of 140.
Use 2 as the next digit of our solution. 
Result so far: 7932.012
Subtracting 810 from 950 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 11:
405 can be fit into 1400 3 times, resulting in a remainder of 185.
Use 3 as the next digit of our solution. 
Result so far: 7932.0123
The remainder is 185 after subtracting 1215 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 12:
405 can be fit into 1850 4 times, resulting in a remainder of 230.
Record the quotient 4 as the next digit in the result. 
Result so far: 7932.01234
If we subtract 1620 from 1850, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 13:
2300 divided by 405 is 5 with a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 7932.012345
If we subtract 2025 from 2300, we 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.

On to step 14:
405 goes into 2750 6 times with a remainder of 320.
Put 6 as the next digit of the answer. 
Result so far: 7932.0123456
Subtracting 2430 from 2750 leaves us with 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 15:
3200 divided by 405 is 7 with a remainder of 365.
The number 7 becomes the next digit in our result. 
Result so far: 7932.01234567
Subtracting 2835 from 3200 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

In conclusion, the division gives 7932.01234567 with a balance of 3.65e-07.
