Let's divide 25702030 by 257
We want to figure out the number of times 25702030 can be divided by 257.

On to step 1:
257 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 257

Let's proceed to step 2:
257 can be fit into 25 0 times, resulting in a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 257

Advancing to step 3:
257 goes into 257 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 257 from 257, we get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 257

Going ahead to step 4:
The number 257 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 257

Let's proceed to step 5:
257 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 257

Moving on to step 6:
If we divide 20 by 257, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 1000.0
If we subtract 0 from 20, we get 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 257

Step 7:
203 divided by 257 is 0 with a remainder of 203.
The next digit of our result is 0. 
Result so far: 10000.0
Subtract 0 from 203 to get 203.
Append the next digit (0) from the dividend to 203 and continue with: 2030 / 257

Let's proceed to step 8:
If we divide 2030 by 257, we get 7 and a remainder of 231.
Write down 7 as next digit of the result. 
Result so far: 100007.0
Subtracting 1799 from 2030 leaves us with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Step 9:
257 can be fit into 2310 8 times, resulting in a remainder of 254.
Write down 8 as next digit of the result. 
Result so far: 100007.8
The remainder is 254 after subtracting 2056 from 2310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Let's proceed to step 10:
When dividing 2540 by 257, we get 9 with a remainder of 227.
Use 9 as the next digit of our solution. 
Result so far: 100007.89
Deduct 2313 from 2540 and we're left with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

On to step 11:
If we divide 2270 by 257, we get 8 and a remainder of 214.
The number 8 becomes the next digit in our result. 
Result so far: 100007.898
If we subtract 2056 from 2270, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 12:
The number 257 fits into 2140 8 times, leaving a remainder of 84.
Record the quotient 8 as the next digit in the result. 
Result so far: 100007.8988
Deduct 2056 from 2140 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final result is 100007.8988 with a remainder of 0.00084.
