138503 divided by 28 
We want to divide 138503 by 28.

On to step 1:
28 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 28

Moving on to step 2:
28 can be fit into 13 0 times, resulting in a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 28

Step 3:
138 divided by 28 is 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 112 from 138 and we're left with 26.
Grab the next digit (5) from the dividend, add it to 26, then carry on: 265 / 28

Let's proceed to step 4:
265 divided by 28 is 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
If we take 252 away from 265, we end up with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 28

Step 5:
28 goes into 130 4 times with a remainder of 18.
The next digit of our result is 4. 
Result so far: 494.0
Subtract 112 from 130 to get 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 28

Moving on to step 6:
When dividing 183 by 28, we get 6 with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 4946.0
The remainder is 15 after subtracting 168 from 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
When dividing 150 by 28, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 4946.5
Deduct 140 from 150 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.

Advancing to step 8:
If we divide 100 by 28, we get 3 and a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 4946.53
Subtract 84 from 100 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.

Let's proceed to step 9:
When dividing 160 by 28, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 4946.535
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.

Let's proceed to step 10:
If we divide 200 by 28, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 4946.5357
Subtracting 196 from 200 leaves us 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 11:
When dividing 40 by 28, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 4946.53571
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.

On to step 12:
The number 28 fits into 120 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 4946.535714
If we take 112 away from 120, we end up 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.

Going ahead to step 13:
If we divide 80 by 28, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 4946.5357142
Deduct 56 from 80 and we're left 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.

Advancing to step 14:
28 goes into 240 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 4946.53571428
Deduct 224 from 240 and we're left 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.

After the division, we end up with 4946.53571428 and a remainder of 1.6e-08.
