Let's divide 48051215 by 28
We want to divide 48051215 by 28.

On to step 1:
28 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 28

Moving on to step 2:
28 can be fit into 48 1 times, resulting in a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 28 from 48 leaves us with 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 28

Moving on to step 3:
28 goes into 200 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 196 away from 200, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 28

Going ahead to step 4:
If we divide 45 by 28, we get 1 and a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 171.0
Deduct 28 from 45 and we're left with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 28

Moving on to step 5:
The number 28 fits into 171 6 times, leaving a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 1716.0
If we subtract 168 from 171, we get 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 28

Advancing to step 6:
28 goes into 32 1 times with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 17161.0
Subtract 28 from 32 to get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 28

Going ahead to step 7:
41 divided by 28 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 171611.0
If we take 28 away from 41, we end up with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 28

Going ahead to step 8:
The number 28 fits into 135 4 times, leaving a remainder of 23.
The next digit of our result is 4. 
Result so far: 1716114.0
Deduct 112 from 135 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 9:
28 goes into 230 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 1716114.8
The remainder is 6 after subtracting 224 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
28 goes into 60 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 1716114.82
Deduct 56 from 60 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.

Let's proceed to step 11:
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: 1716114.821
Subtracting 28 from 40 leaves us 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 12:
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: 1716114.8214
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.

Step 13:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 1716114.82142
The remainder is 24 after subtracting 56 from 80.
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.
Write down 8 as next digit of the result. 
Result so far: 1716114.821428
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 15:
28 goes into 160 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 1716114.8214285
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.

Going ahead to step 16:
If we divide 200 by 28, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 1716114.82142857
If we take 196 away from 200, 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.

The final result is 1716114.82142857 with a remainder of 4e-09.
