We look at the division of 49943095 by 399 
We want to divide 49943095 by 399.

Moving on to step 1:
When dividing 4 by 399, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 399

Moving on to step 2:
49 divided by 399 is 0 with a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Take the next digit (9) from the dividend and append it to 49, then repeat: 499 / 399

Moving on to step 3:
When dividing 499 by 399, we get 1 with a remainder of 100.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 399 away from 499, we end up with 100.
Fetch the next digit (4) from the dividend, attach it to 100 and continue: 1004 / 399

Step 4:
When dividing 1004 by 399, we get 2 with a remainder of 206.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 206 after subtracting 798 from 1004.
Grab the next digit (3) from the dividend, add it to 206, then carry on: 2063 / 399

Let's proceed to step 5:
399 goes into 2063 5 times with a remainder of 68.
The next digit of our result is 5. 
Result so far: 125.0
The remainder is 68 after subtracting 1995 from 2063.
Fetch the next digit (0) from the dividend, attach it to 68 and continue: 680 / 399

On to step 6:
399 goes into 680 1 times with a remainder of 281.
Record the quotient 1 as the next digit in the result. 
Result so far: 1251.0
Deduct 399 from 680 and we're left with 281.
Append the next digit (9) from the dividend to 281 and continue with: 2819 / 399

Step 7:
If we divide 2819 by 399, we get 7 and a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 12517.0
If we take 2793 away from 2819, we end up with 26.
Grab the next digit (5) from the dividend, add it to 26, then carry on: 265 / 399

Step 8:
When dividing 265 by 399, we get 0 with a remainder of 265.
Use 0 as the next digit of our solution. 
Result so far: 125170.0
Subtracting 0 from 265 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Advancing to step 9:
399 goes into 2650 6 times with a remainder of 256.
Put 6 as the next digit of the answer. 
Result so far: 125170.6
Deduct 2394 from 2650 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 10:
The number 399 fits into 2560 6 times, leaving a remainder of 166.
Put 6 as the next digit of the answer. 
Result so far: 125170.66
If we subtract 2394 from 2560, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

The final outcome is 125170.66, with a leftover of 0.166.
