We're dividing 138570 by 28 
We want to figure out the number of times 138570 can be divided by 28.

Let's proceed to step 1:
28 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 28

Let's proceed to step 2:
28 can be fit into 13 0 times, resulting in a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 28

Moving on to step 3:
28 can be fit into 138 4 times, resulting in a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 26 after subtracting 112 from 138.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 28

Let's proceed to step 4:
The number 28 fits into 265 9 times, leaving a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we subtract 252 from 265, we get 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 28

Moving on to step 5:
When dividing 137 by 28, we get 4 with a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 494.0
Subtract 112 from 137 to get 25.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 28

Step 6:
If we divide 250 by 28, we get 8 and a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 4948.0
If we take 224 away from 250, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
If we divide 260 by 28, we get 9 and a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 4948.9
If we subtract 252 from 260, 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.

Advancing to step 8:
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: 4948.92
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.

Going ahead to step 9:
28 goes into 240 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 4948.928
If we subtract 224 from 240, we 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.

Moving on to step 10:
When dividing 160 by 28, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 4948.9285
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.

On to step 11:
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: 4948.92857
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.

Step 12:
28 goes into 40 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 4948.928571
Subtract 28 from 40 to 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.

Advancing to step 13:
When dividing 120 by 28, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4948.9285714
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.

Advancing to step 14:
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: 4948.92857142
Subtracting 56 from 80 leaves us 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.

The quotient of the division is 4948.92857142, and the remainder is 2.4e-08.
