We're dividing 405590 by 28 
We want to divide 405590 by 28.

Let's proceed to step 1:
When dividing 4 by 28, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 28

Step 2:
28 can be fit into 40 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
If we take 28 away from 40, we end up with 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 28

Going ahead to step 3:
If we divide 125 by 28, we get 4 and a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 112 from 125 and we're left with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 28

Moving on to step 4:
When dividing 135 by 28, we get 4 with a remainder of 23.
The next digit of our result is 4. 
Result so far: 144.0
The remainder is 23 after subtracting 112 from 135.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 28

Step 5:
When dividing 239 by 28, we get 8 with a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 1448.0
Deduct 224 from 239 and we're left with 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 28

Let's proceed to step 6:
If we divide 150 by 28, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 14485.0
If we take 140 away from 150, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
100 divided by 28 is 3 with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 14485.3
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
If we divide 160 by 28, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 14485.35
If we take 140 away from 160, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
200 divided by 28 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 14485.357
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 14485.3571
The remainder is 12 after subtracting 28 from 40.
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 11:
When dividing 120 by 28, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 14485.35714
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.

On to step 12:
When dividing 80 by 28, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 14485.357142
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.

Moving on to step 13:
When dividing 240 by 28, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 14485.3571428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 14485.35714285
Deduct 140 from 160 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 14485.35714285, with a leftover of 2e-08.
