We look at the division of 49642934 by 399 
We're looking to find how many times 399 goes into 49642934.

Let's proceed to step 1:
399 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 399

Moving on to step 2:
399 goes into 49 0 times with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Grab the next digit (6) from the dividend, add it to 49, then carry on: 496 / 399

On to step 3:
399 can be fit into 496 1 times, resulting in a remainder of 97.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 399 away from 496, we end up with 97.
Bring next digit (4) of the dividend behind the 97 and repeat the process: 974 / 399

Going ahead to step 4:
399 can be fit into 974 2 times, resulting in a remainder of 176.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 798 from 974 to get 176.
Include the next digit (2) from the dividend after 176, then repeat: 1762 / 399

On to step 5:
399 can be fit into 1762 4 times, resulting in a remainder of 166.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
If we subtract 1596 from 1762, we get 166.
Include the next digit (9) from the dividend after 166, then repeat: 1669 / 399

On to step 6:
When dividing 1669 by 399, we get 4 with a remainder of 73.
The next digit of our result is 4. 
Result so far: 1244.0
Subtracting 1596 from 1669 leaves us with 73.
Bring next digit (3) of the dividend behind the 73 and repeat the process: 733 / 399

Let's proceed to step 7:
399 can be fit into 733 1 times, resulting in a remainder of 334.
The number 1 becomes the next digit in our result. 
Result so far: 12441.0
The remainder is 334 after subtracting 399 from 733.
Take the next digit (4) from the dividend and append it to 334, then repeat: 3344 / 399

Advancing to step 8:
When dividing 3344 by 399, we get 8 with a remainder of 152.
Record the quotient 8 as the next digit in the result. 
Result so far: 124418.0
If we subtract 3192 from 3344, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 9:
When dividing 1520 by 399, we get 3 with a remainder of 323.
Put 3 as the next digit of the answer. 
Result so far: 124418.3
If we subtract 1197 from 1520, we get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Advancing to step 10:
399 goes into 3230 8 times with a remainder of 38.
The next digit of our result is 8. 
Result so far: 124418.38
Subtracting 3192 from 3230 leaves us 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.

Step 11:
The number 399 fits into 380 0 times, leaving a remainder of 380.
Put 0 as the next digit of the answer. 
Result so far: 124418.38
Deduct 0 from 380 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 12:
399 goes into 3800 9 times with a remainder of 209.
Put 9 as the next digit of the answer. 
Result so far: 124418.3809
Subtracting 3591 from 3800 leaves us with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Advancing to step 13:
When dividing 2090 by 399, we get 5 with a remainder of 95.
The next digit of our result is 5. 
Result so far: 124418.38095
Deduct 1995 from 2090 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 14:
399 can be fit into 950 2 times, resulting in a remainder of 152.
Use 2 as the next digit of our solution. 
Result so far: 124418.380952
If we take 798 away from 950, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 15:
399 goes into 1520 3 times with a remainder of 323.
Use 3 as the next digit of our solution. 
Result so far: 124418.3809523
Deduct 1197 from 1520 and we're left with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Advancing to step 16:
If we divide 3230 by 399, we get 8 and a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 124418.38095238
Subtracting 3192 from 3230 leaves us 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.

Our division results in 124418.38095238 with a remaining 3.8e-08.
