30605457 ÷ 336 
We want to divide 30605457 by 336.

Going ahead to step 1:
336 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 336

Advancing to step 2:
If we divide 30 by 336, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 336

Going ahead to step 3:
336 goes into 306 0 times with a remainder of 306.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 306 leaves us with 306.
Take the next digit (0) from the dividend and append it to 306, then repeat: 3060 / 336

Going ahead to step 4:
If we divide 3060 by 336, we get 9 and a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 3024 from 3060 and we're left with 36.
Grab the next digit (5) from the dividend, add it to 36, then carry on: 365 / 336

Advancing to step 5:
The number 336 fits into 365 1 times, leaving a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 91.0
Subtract 336 from 365 to get 29.
Fetch the next digit (4) from the dividend, attach it to 29 and continue: 294 / 336

Step 6:
294 divided by 336 is 0 with a remainder of 294.
Put 0 as the next digit of the answer. 
Result so far: 910.0
Subtract 0 from 294 to get 294.
Include the next digit (5) from the dividend after 294, then repeat: 2945 / 336

Let's proceed to step 7:
When dividing 2945 by 336, we get 8 with a remainder of 257.
Put 8 as the next digit of the answer. 
Result so far: 9108.0
Deduct 2688 from 2945 and we're left with 257.
Grab the next digit (7) from the dividend, add it to 257, then carry on: 2577 / 336

Step 8:
336 goes into 2577 7 times with a remainder of 225.
Use 7 as the next digit of our solution. 
Result so far: 91087.0
The remainder is 225 after subtracting 2352 from 2577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 9:
336 goes into 2250 6 times with a remainder of 234.
Use 6 as the next digit of our solution. 
Result so far: 91087.6
Deduct 2016 from 2250 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 10:
When dividing 2340 by 336, we get 6 with a remainder of 324.
Write down 6 as next digit of the result. 
Result so far: 91087.66
The remainder is 324 after subtracting 2016 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

The final outcome is 91087.66, with a leftover of 0.324.
