We divide 638213 by 28
Our goal is to divide 638213 by 28.

Step 1:
The number 28 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 28

Let's proceed to step 2:
The number 28 fits into 63 2 times, leaving a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 56 from 63, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 28

Let's proceed to step 3:
78 divided by 28 is 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 56 from 78, we get 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 28

Step 4:
When dividing 222 by 28, we get 7 with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 227.0
If we take 196 away from 222, we end up with 26.
Fetch the next digit (1) from the dividend, attach it to 26 and continue: 261 / 28

Going ahead to step 5:
The number 28 fits into 261 9 times, leaving a remainder of 9.
The next digit of our result is 9. 
Result so far: 2279.0
If we take 252 away from 261, we end up with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 28

Advancing to step 6:
93 divided by 28 is 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 22793.0
Subtract 84 from 93 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
28 can be fit into 90 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 22793.3
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
When dividing 60 by 28, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 22793.32
If we take 56 away from 60, we end up 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 9:
28 goes into 40 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 22793.321
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.

Going ahead to step 10:
If we divide 120 by 28, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 22793.3214
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.

Step 11:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 22793.32142
Subtract 56 from 80 to 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.

Step 12:
When dividing 240 by 28, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 22793.321428
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.

Advancing to step 13:
28 goes into 160 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 22793.3214285
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.

On to step 14:
200 divided by 28 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 22793.32142857
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.

Our division results in 22793.32142857 with a remaining 4e-09.
