638466 divided by 28 
We're looking to find how many times 28 goes into 638466.

Going ahead to step 1:
28 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 28

On to step 2:
When dividing 63 by 28, we get 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 56 from 63, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 28

Step 3:
If we divide 78 by 28, we get 2 and a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Deduct 56 from 78 and we're left with 22.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 28

Going ahead to step 4:
If we divide 224 by 28, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 228.0
If we take 224 away from 224, we end up with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 28

On to step 5:
6 divided by 28 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 2280.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 28

Let's proceed to step 6:
If we divide 66 by 28, we get 2 and a remainder of 10.
The next digit of our result is 2. 
Result so far: 22802.0
Deduct 56 from 66 and we're left 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.

Step 7:
28 goes into 100 3 times with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 22802.3
Subtracting 84 from 100 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.

Going ahead 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: 22802.35
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.

Moving on to step 9:
When dividing 200 by 28, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 22802.357
The remainder is 4 after subtracting 196 from 200.
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 10:
If we divide 40 by 28, we get 1 and a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 22802.3571
If we take 28 away from 40, we end up 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.

Advancing to step 11:
If we divide 120 by 28, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 22802.35714
Subtract 112 from 120 to 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.

Going ahead to step 12:
If we divide 80 by 28, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 22802.357142
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 13:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 22802.3571428
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.

Advancing to step 14:
160 divided by 28 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 22802.35714285
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.

Our division results in 22802.35714285 with a remaining 2e-08.
