89436548 divided by 257 
Our goal is to divide 89436548 by 257.

Advancing to step 1:
8 divided by 257 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 257

Going ahead to step 2:
When dividing 89 by 257, we get 0 with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Bring next digit (4) of the dividend behind the 89 and repeat the process: 894 / 257

On to step 3:
894 divided by 257 is 3 with a remainder of 123.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 771 from 894 to get 123.
Fetch the next digit (3) from the dividend, attach it to 123 and continue: 1233 / 257

Advancing to step 4:
The number 257 fits into 1233 4 times, leaving a remainder of 205.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Deduct 1028 from 1233 and we're left with 205.
Grab the next digit (6) from the dividend, add it to 205, then carry on: 2056 / 257

Going ahead to step 5:
When dividing 2056 by 257, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 348.0
If we subtract 2056 from 2056, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 257

Step 6:
If we divide 5 by 257, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 3480.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 257

On to step 7:
257 can be fit into 54 0 times, resulting in a remainder of 54.
The next digit of our result is 0. 
Result so far: 34800.0
Subtracting 0 from 54 leaves us with 54.
Fetch the next digit (8) from the dividend, attach it to 54 and continue: 548 / 257

Going ahead to step 8:
When dividing 548 by 257, we get 2 with a remainder of 34.
The next digit of our result is 2. 
Result so far: 348002.0
If we subtract 514 from 548, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
When dividing 340 by 257, we get 1 with a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 348002.1
If we take 257 away from 340, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 10:
830 divided by 257 is 3 with a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 348002.13
If we subtract 771 from 830, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 11:
If we divide 590 by 257, we get 2 and a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 348002.132
Deduct 514 from 590 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 12:
760 divided by 257 is 2 with a remainder of 246.
The next digit of our result is 2. 
Result so far: 348002.1322
If we take 514 away from 760, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Our division results in 348002.1322 with a remaining 0.00246.
