We look at the division of 4080388 by 605 
We're looking to find how many times 605 goes into 4080388.

Let's proceed to step 1:
The number 605 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 605

Advancing to step 2:
If we divide 40 by 605, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 605

Step 3:
When dividing 408 by 605, we get 0 with a remainder of 408.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 408 and we're left with 408.
Grab the next digit (0) from the dividend, add it to 408, then carry on: 4080 / 605

Let's proceed to step 4:
When dividing 4080 by 605, we get 6 with a remainder of 450.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 450 after subtracting 3630 from 4080.
Fetch the next digit (3) from the dividend, attach it to 450 and continue: 4503 / 605

Step 5:
605 can be fit into 4503 7 times, resulting in a remainder of 268.
The next digit of our result is 7. 
Result so far: 67.0
The remainder is 268 after subtracting 4235 from 4503.
Bring next digit (8) of the dividend behind the 268 and repeat the process: 2688 / 605

Moving on to step 6:
When dividing 2688 by 605, we get 4 with a remainder of 268.
Use 4 as the next digit of our solution. 
Result so far: 674.0
Deduct 2420 from 2688 and we're left with 268.
Fetch the next digit (8) from the dividend, attach it to 268 and continue: 2688 / 605

Going ahead to step 7:
When dividing 2688 by 605, we get 4 with a remainder of 268.
Put 4 as the next digit of the answer. 
Result so far: 6744.0
If we take 2420 away from 2688, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Step 8:
If we divide 2680 by 605, we get 4 and a remainder of 260.
Record the quotient 4 as the next digit in the result. 
Result so far: 6744.4
If we subtract 2420 from 2680, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 9:
When dividing 2600 by 605, we get 4 with a remainder of 180.
The number 4 becomes the next digit in our result. 
Result so far: 6744.44
Subtract 2420 from 2600 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

In conclusion, the division gives 6744.44 with a balance of 0.18.
