49123198 ÷ 408 
We want to figure out the number of times 49123198 can be divided by 408.

Moving on to step 1:
408 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 408

Going ahead to step 2:
408 can be fit into 49 0 times, resulting in a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Fetch the next digit (1) from the dividend, attach it to 49 and continue: 491 / 408

Advancing to step 3:
408 goes into 491 1 times with a remainder of 83.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 408 from 491 and we're left with 83.
Grab the next digit (2) from the dividend, add it to 83, then carry on: 832 / 408

Going ahead to step 4:
408 goes into 832 2 times with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 816 from 832 and we're left with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 408

On to step 5:
408 can be fit into 163 0 times, resulting in a remainder of 163.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
Subtracting 0 from 163 leaves us with 163.
Bring next digit (1) of the dividend behind the 163 and repeat the process: 1631 / 408

Step 6:
408 goes into 1631 3 times with a remainder of 407.
The next digit of our result is 3. 
Result so far: 1203.0
The remainder is 407 after subtracting 1224 from 1631.
Bring next digit (9) of the dividend behind the 407 and repeat the process: 4079 / 408

Advancing to step 7:
The number 408 fits into 4079 9 times, leaving a remainder of 407.
The number 9 becomes the next digit in our result. 
Result so far: 12039.0
If we take 3672 away from 4079, we end up with 407.
Grab the next digit (8) from the dividend, add it to 407, then carry on: 4078 / 408

Step 8:
408 goes into 4078 9 times with a remainder of 406.
Put 9 as the next digit of the answer. 
Result so far: 120399.0
Deduct 3672 from 4078 and we're left with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Going ahead to step 9:
408 goes into 4060 9 times with a remainder of 388.
Record the quotient 9 as the next digit in the result. 
Result so far: 120399.9
The remainder is 388 after subtracting 3672 from 4060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 10:
If we divide 3880 by 408, we get 9 and a remainder of 208.
Put 9 as the next digit of the answer. 
Result so far: 120399.99
If we subtract 3672 from 3880, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

After the division, we end up with 120399.99 and a remainder of 0.208.
