668496 ÷ 49 
We're looking to find how many times 49 goes into 668496.

Going ahead to step 1:
If we divide 6 by 49, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 49

On to step 2:
66 divided by 49 is 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 49 away from 66, we end up with 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 49

Going ahead to step 3:
49 can be fit into 178 3 times, resulting in a remainder of 31.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 147 from 178, we get 31.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 49

Moving on to step 4:
If we divide 314 by 49, we get 6 and a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 136.0
Deduct 294 from 314 and we're left with 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 49

Let's proceed to step 5:
When dividing 209 by 49, we get 4 with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 1364.0
The remainder is 13 after subtracting 196 from 209.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 49

Going ahead to step 6:
If we divide 136 by 49, we get 2 and a remainder of 38.
The next digit of our result is 2. 
Result so far: 13642.0
If we take 98 away from 136, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
49 goes into 380 7 times with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 13642.7
If we subtract 343 from 380, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 8:
49 goes into 370 7 times with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 13642.77
If we take 343 away from 370, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 13642.77 and a remainder of 0.027.
