We divide 20511150 by 257
Our goal is to divide 20511150 by 257.

Moving on to step 1:
257 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 257

Step 2:
20 divided by 257 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 257

Moving on to step 3:
257 goes into 205 0 times with a remainder of 205.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 205 and we're left with 205.
Fetch the next digit (1) from the dividend, attach it to 205 and continue: 2051 / 257

Let's proceed to step 4:
2051 divided by 257 is 7 with a remainder of 252.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 1799 from 2051 and we're left with 252.
Bring next digit (1) of the dividend behind the 252 and repeat the process: 2521 / 257

Moving on to step 5:
The number 257 fits into 2521 9 times, leaving a remainder of 208.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
The remainder is 208 after subtracting 2313 from 2521.
Take the next digit (1) from the dividend and append it to 208, then repeat: 2081 / 257

On to step 6:
When dividing 2081 by 257, we get 8 with a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 798.0
Subtract 2056 from 2081 to get 25.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 257

Let's proceed to step 7:
257 can be fit into 255 0 times, resulting in a remainder of 255.
The next digit of our result is 0. 
Result so far: 7980.0
Deduct 0 from 255 and we're left with 255.
Append the next digit (0) from the dividend to 255 and continue with: 2550 / 257

On to step 8:
257 goes into 2550 9 times with a remainder of 237.
Write down 9 as next digit of the result. 
Result so far: 79809.0
If we subtract 2313 from 2550, we get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

On to step 9:
257 goes into 2370 9 times with a remainder of 57.
The next digit of our result is 9. 
Result so far: 79809.9
Deduct 2313 from 2370 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 10:
If we divide 570 by 257, we get 2 and a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 79809.92
If we take 514 away from 570, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
257 goes into 560 2 times with a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 79809.922
Subtract 514 from 560 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

In conclusion, the division gives 79809.922 with a balance of 0.0046.
