We're dividing 431668 by 28 
We want to figure out the number of times 431668 can be divided by 28.

Step 1:
4 divided by 28 is 0 with 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.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 28

On to step 2:
43 divided by 28 is 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 28 from 43 to get 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 28

Let's proceed to step 3:
If we divide 151 by 28, we get 5 and a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 140 from 151 to get 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 28

Let's proceed to step 4:
The number 28 fits into 116 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 154.0
Subtract 112 from 116 to get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 28

Going ahead to step 5:
The number 28 fits into 46 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1541.0
Deduct 28 from 46 and we're left with 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 28

Step 6:
28 goes into 188 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 15416.0
If we subtract 168 from 188, we 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.

Going ahead to step 7:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 15416.7
If we subtract 196 from 200, we 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.

On to step 8:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 15416.71
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.

On to step 9:
120 divided by 28 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 15416.714
If we subtract 112 from 120, we get 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 10:
The number 28 fits into 80 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 15416.7142
If we take 56 away from 80, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
If we divide 240 by 28, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 15416.71428
If we take 224 away from 240, 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.

Let's proceed to step 12:
If we divide 160 by 28, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 15416.714285
If we subtract 140 from 160, we 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.

Going ahead to step 13:
28 can be fit into 200 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 15416.7142857
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.

Step 14:
When dividing 40 by 28, we get 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 15416.71428571
If we subtract 28 from 40, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 15416.71428571 with a balance of 1.2e-08.
