39057481 ÷ 405 
Our goal is to divide 39057481 by 405.

Moving on to step 1:
405 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 405

Let's proceed to step 2:
405 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 405

Going ahead to step 3:
390 divided by 405 is 0 with a remainder of 390.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 390 and we're left with 390.
Append the next digit (5) from the dividend to 390 and continue with: 3905 / 405

Step 4:
If we divide 3905 by 405, we get 9 and a remainder of 260.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 3645 from 3905, we get 260.
Grab the next digit (7) from the dividend, add it to 260, then carry on: 2607 / 405

Advancing to step 5:
2607 divided by 405 is 6 with a remainder of 177.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
If we subtract 2430 from 2607, we get 177.
Fetch the next digit (4) from the dividend, attach it to 177 and continue: 1774 / 405

On to step 6:
1774 divided by 405 is 4 with a remainder of 154.
Write down 4 as next digit of the result. 
Result so far: 964.0
If we subtract 1620 from 1774, we get 154.
Fetch the next digit (8) from the dividend, attach it to 154 and continue: 1548 / 405

Let's proceed to step 7:
405 goes into 1548 3 times with a remainder of 333.
Record the quotient 3 as the next digit in the result. 
Result so far: 9643.0
Subtract 1215 from 1548 to get 333.
Grab the next digit (1) from the dividend, add it to 333, then carry on: 3331 / 405

Advancing to step 8:
The number 405 fits into 3331 8 times, leaving a remainder of 91.
Record the quotient 8 as the next digit in the result. 
Result so far: 96438.0
Deduct 3240 from 3331 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 9:
405 goes into 910 2 times with a remainder of 100.
The next digit of our result is 2. 
Result so far: 96438.2
Subtract 810 from 910 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 10:
405 goes into 1000 2 times with a remainder of 190.
Put 2 as the next digit of the answer. 
Result so far: 96438.22
Subtract 810 from 1000 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The final result is 96438.22 with a remainder of 0.19.
