We're dividing 74512494 by 257 
Let's see how many times 257 fits into 74512494.

Advancing to step 1:
When dividing 7 by 257, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 257

Step 2:
When dividing 74 by 257, we get 0 with a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Grab the next digit (5) from the dividend, add it to 74, then carry on: 745 / 257

Step 3:
745 divided by 257 is 2 with a remainder of 231.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 514 from 745 and we're left with 231.
Take the next digit (1) from the dividend and append it to 231, then repeat: 2311 / 257

Advancing to step 4:
The number 257 fits into 2311 8 times, leaving a remainder of 255.
The next digit of our result is 8. 
Result so far: 28.0
Subtract 2056 from 2311 to get 255.
Include the next digit (2) from the dividend after 255, then repeat: 2552 / 257

Let's proceed to step 5:
When dividing 2552 by 257, we get 9 with a remainder of 239.
The number 9 becomes the next digit in our result. 
Result so far: 289.0
The remainder is 239 after subtracting 2313 from 2552.
Bring next digit (4) of the dividend behind the 239 and repeat the process: 2394 / 257

Step 6:
When dividing 2394 by 257, we get 9 with a remainder of 81.
Record the quotient 9 as the next digit in the result. 
Result so far: 2899.0
The remainder is 81 after subtracting 2313 from 2394.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 257

On to step 7:
The number 257 fits into 819 3 times, leaving a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 28993.0
Deduct 771 from 819 and we're left with 48.
Fetch the next digit (4) from the dividend, attach it to 48 and continue: 484 / 257

Let's proceed to step 8:
484 divided by 257 is 1 with a remainder of 227.
Record the quotient 1 as the next digit in the result. 
Result so far: 289931.0
The remainder is 227 after subtracting 257 from 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Going ahead to step 9:
When dividing 2270 by 257, we get 8 with a remainder of 214.
Write down 8 as next digit of the result. 
Result so far: 289931.8
Subtract 2056 from 2270 to 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 10:
When dividing 2140 by 257, we get 8 with a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 289931.88
The remainder is 84 after subtracting 2056 from 2140.
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 outcome is 289931.88, with a leftover of 0.084.
