30917720 ÷ 248 
We're looking to find how many times 248 goes into 30917720.

Moving on to step 1:
3 divided by 248 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 248

Going ahead to step 2:
248 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 248

Step 3:
309 divided by 248 is 1 with a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 248 from 309 to get 61.
Include the next digit (1) from the dividend after 61, then repeat: 611 / 248

Advancing to step 4:
The number 248 fits into 611 2 times, leaving a remainder of 115.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 115 after subtracting 496 from 611.
Grab the next digit (7) from the dividend, add it to 115, then carry on: 1157 / 248

Going ahead to step 5:
248 can be fit into 1157 4 times, resulting in a remainder of 165.
Write down 4 as next digit of the result. 
Result so far: 124.0
Subtract 992 from 1157 to get 165.
Take the next digit (7) from the dividend and append it to 165, then repeat: 1657 / 248

Let's proceed to step 6:
The number 248 fits into 1657 6 times, leaving a remainder of 169.
Use 6 as the next digit of our solution. 
Result so far: 1246.0
The remainder is 169 after subtracting 1488 from 1657.
Grab the next digit (2) from the dividend, add it to 169, then carry on: 1692 / 248

Step 7:
The number 248 fits into 1692 6 times, leaving a remainder of 204.
The number 6 becomes the next digit in our result. 
Result so far: 12466.0
Deduct 1488 from 1692 and we're left with 204.
Grab the next digit (0) from the dividend, add it to 204, then carry on: 2040 / 248

On to step 8:
If we divide 2040 by 248, we get 8 and a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 124668.0
If we subtract 1984 from 2040, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
248 can be fit into 560 2 times, resulting in a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 124668.2
If we subtract 496 from 560, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
248 goes into 640 2 times with a remainder of 144.
Put 2 as the next digit of the answer. 
Result so far: 124668.22
If we subtract 496 from 640, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The quotient of the division is 124668.22, and the remainder is 0.144.
