4068437 ÷ 405 
We're looking to find how many times 405 goes into 4068437.

Advancing 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
The remainder is 4 after subtracting 0 from 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 405

Let's proceed to step 2:
When dividing 40 by 405, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 405

On to step 3:
If we divide 406 by 405, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 405 from 406 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 405

Moving on to step 4:
405 goes into 18 0 times with a remainder of 18.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 18, we get 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 405

Step 5:
405 can be fit into 184 0 times, resulting in a remainder of 184.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtracting 0 from 184 leaves us with 184.
Fetch the next digit (3) from the dividend, attach it to 184 and continue: 1843 / 405

Let's proceed to step 6:
When dividing 1843 by 405, we get 4 with a remainder of 223.
Record the quotient 4 as the next digit in the result. 
Result so far: 1004.0
The remainder is 223 after subtracting 1620 from 1843.
Take the next digit (7) from the dividend and append it to 223, then repeat: 2237 / 405

Going ahead to step 7:
When dividing 2237 by 405, we get 5 with a remainder of 212.
Use 5 as the next digit of our solution. 
Result so far: 10045.0
If we take 2025 away from 2237, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 8:
When dividing 2120 by 405, we get 5 with a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 10045.5
Subtract 2025 from 2120 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 9:
950 divided by 405 is 2 with a remainder of 140.
Use 2 as the next digit of our solution. 
Result so far: 10045.52
If we take 810 away from 950, we end up 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.

Let's proceed to step 10:
405 goes into 1400 3 times with a remainder of 185.
Use 3 as the next digit of our solution. 
Result so far: 10045.523
If we take 1215 away from 1400, we end up with 185.
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 11:
The number 405 fits into 1850 4 times, leaving a remainder of 230.
Record the quotient 4 as the next digit in the result. 
Result so far: 10045.5234
Subtracting 1620 from 1850 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 12:
405 can be fit into 2300 5 times, resulting in a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 10045.52345
The remainder is 275 after subtracting 2025 from 2300.
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 13:
The number 405 fits into 2750 6 times, leaving a remainder of 320.
Record the quotient 6 as the next digit in the result. 
Result so far: 10045.523456
If we take 2430 away from 2750, we end up 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 14:
When dividing 3200 by 405, we get 7 with a remainder of 365.
Use 7 as the next digit of our solution. 
Result so far: 10045.5234567
If we take 2835 away from 3200, we end up 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.

On to step 15:
405 can be fit into 3650 9 times, resulting in a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 10045.52345679
Subtract 3645 from 3650 to 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.

After the division, we end up with 10045.52345679 and a remainder of 5e-09.
