We're dividing 405315 by 28 
Our goal is to divide 405315 by 28.

Step 1:
28 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 28

Advancing to step 2:
28 goes into 40 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 28 from 40, we get 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 28

On to step 3:
28 goes into 125 4 times with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 13 after subtracting 112 from 125.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 28

Let's proceed to step 4:
The number 28 fits into 133 4 times, leaving a remainder of 21.
Write down 4 as next digit of the result. 
Result so far: 144.0
Subtract 112 from 133 to get 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 28

On to step 5:
The number 28 fits into 211 7 times, leaving a remainder of 15.
The next digit of our result is 7. 
Result so far: 1447.0
The remainder is 15 after subtracting 196 from 211.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 28

On to step 6:
155 divided by 28 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 14475.0
Deduct 140 from 155 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 7:
150 divided by 28 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 14475.5
The remainder is 10 after subtracting 140 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
28 goes into 100 3 times with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 14475.53
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 14475.535
Subtract 140 from 160 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 14475.5357
Deduct 196 from 200 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 14475.53571
Deduct 28 from 40 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
120 divided by 28 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 14475.535714
Subtracting 112 from 120 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
When dividing 80 by 28, we get 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 14475.5357142
If we subtract 56 from 80, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
240 divided by 28 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 14475.53571428
Subtracting 224 from 240 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 14475.53571428, and the remainder is 1.6e-08.
