We look at the division of 5278002 by 405 
Let's see how many times 405 fits into 5278002.

Step 1:
When dividing 5 by 405, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 405

Going ahead to step 2:
If we divide 52 by 405, we get 0 and a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Include the next digit (7) from the dividend after 52, then repeat: 527 / 405

On to step 3:
527 divided by 405 is 1 with a remainder of 122.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 405 from 527 to get 122.
Grab the next digit (8) from the dividend, add it to 122, then carry on: 1228 / 405

Step 4:
If we divide 1228 by 405, we get 3 and a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 1215 from 1228, we get 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 405

Step 5:
When dividing 130 by 405, we get 0 with a remainder of 130.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
If we take 0 away from 130, we end up with 130.
Fetch the next digit (0) from the dividend, attach it to 130 and continue: 1300 / 405

On to step 6:
The number 405 fits into 1300 3 times, leaving a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 1303.0
If we take 1215 away from 1300, we end up with 85.
Take the next digit (2) from the dividend and append it to 85, then repeat: 852 / 405

Moving on to step 7:
405 goes into 852 2 times with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 13032.0
The remainder is 42 after subtracting 810 from 852.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
When dividing 420 by 405, we get 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 13032.1
Subtract 405 from 420 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
150 divided by 405 is 0 with a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 13032.1
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 10:
If we divide 1500 by 405, we get 3 and a remainder of 285.
Use 3 as the next digit of our solution. 
Result so far: 13032.103
Subtract 1215 from 1500 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 11:
If we divide 2850 by 405, we get 7 and a remainder of 15.
The next digit of our result is 7. 
Result so far: 13032.1037
Deduct 2835 from 2850 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
When dividing 150 by 405, we get 0 with a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 13032.1037
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 13:
If we divide 1500 by 405, we get 3 and a remainder of 285.
Record the quotient 3 as the next digit in the result. 
Result so far: 13032.103703
The remainder is 285 after subtracting 1215 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 14:
When dividing 2850 by 405, we get 7 with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 13032.1037037
Subtract 2835 from 2850 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 15:
405 goes into 150 0 times with a remainder of 150.
The next digit of our result is 0. 
Result so far: 13032.1037037
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final result is 13032.1037037 with a remainder of 1.5e-07.
