We look at the division of 257818 by 28 
We want to figure out the number of times 257818 can be divided by 28.

Step 1:
When dividing 2 by 28, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 28

On to step 2:
If we divide 25 by 28, we get 0 and a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Include the next digit (7) from the dividend after 25, then repeat: 257 / 28

Moving on to step 3:
28 goes into 257 9 times with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 252 from 257 leaves us with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 28

Moving on to step 4:
The number 28 fits into 58 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 92.0
If we subtract 56 from 58, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 28

Let's proceed to step 5:
The number 28 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 920.0
Subtract 0 from 21 to get 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 28

Advancing to step 6:
If we divide 218 by 28, we get 7 and a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 9207.0
If we subtract 196 from 218, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
28 goes into 220 7 times with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 9207.7
If we take 196 away from 220, 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.

Advancing to step 8:
When dividing 240 by 28, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 9207.78
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.

Let's proceed to step 9:
If we divide 160 by 28, we get 5 and a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 9207.785
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.

Step 10:
200 divided by 28 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 9207.7857
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.

Going ahead to step 11:
40 divided by 28 is 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 9207.78571
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 12:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 9207.785714
Deduct 112 from 120 and we're left 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.

Moving on to step 13:
80 divided by 28 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 9207.7857142
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:
When dividing 240 by 28, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 9207.78571428
If we take 224 away from 240, we end up 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.

The final outcome is 9207.78571428, with a leftover of 1.6e-08.
