49392135 divided by 402 
Our goal is to divide 49392135 by 402.

Going ahead to step 1:
The number 402 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 402

On to step 2:
402 can be fit into 49 0 times, resulting in a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Grab the next digit (3) from the dividend, add it to 49, then carry on: 493 / 402

Going ahead to step 3:
402 goes into 493 1 times with a remainder of 91.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 402 from 493 and we're left with 91.
Bring next digit (9) of the dividend behind the 91 and repeat the process: 919 / 402

Moving on to step 4:
The number 402 fits into 919 2 times, leaving a remainder of 115.
The next digit of our result is 2. 
Result so far: 12.0
If we take 804 away from 919, we end up with 115.
Take the next digit (2) from the dividend and append it to 115, then repeat: 1152 / 402

Moving on to step 5:
The number 402 fits into 1152 2 times, leaving a remainder of 348.
Write down 2 as next digit of the result. 
Result so far: 122.0
Deduct 804 from 1152 and we're left with 348.
Grab the next digit (1) from the dividend, add it to 348, then carry on: 3481 / 402

Advancing to step 6:
If we divide 3481 by 402, we get 8 and a remainder of 265.
Put 8 as the next digit of the answer. 
Result so far: 1228.0
Deduct 3216 from 3481 and we're left with 265.
Grab the next digit (3) from the dividend, add it to 265, then carry on: 2653 / 402

Moving on to step 7:
402 goes into 2653 6 times with a remainder of 241.
Put 6 as the next digit of the answer. 
Result so far: 12286.0
Subtract 2412 from 2653 to get 241.
Take the next digit (5) from the dividend and append it to 241, then repeat: 2415 / 402

Step 8:
402 can be fit into 2415 6 times, resulting in a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 122866.0
Subtract 2412 from 2415 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
If we divide 30 by 402, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 122866.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
The number 402 fits into 300 0 times, leaving a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 122866.0
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 122866.0, with a leftover of 0.3.
