50811987 ÷ 338 
We want to figure out the number of times 50811987 can be divided by 338.

Moving on to step 1:
338 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 338

Let's proceed to step 2:
When dividing 50 by 338, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Include the next digit (8) from the dividend after 50, then repeat: 508 / 338

Going ahead to step 3:
If we divide 508 by 338, we get 1 and a remainder of 170.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 338 from 508 and we're left with 170.
Bring next digit (1) of the dividend behind the 170 and repeat the process: 1701 / 338

Step 4:
1701 divided by 338 is 5 with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 1690 from 1701 to get 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 338

Step 5:
The number 338 fits into 111 0 times, leaving a remainder of 111.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
Deduct 0 from 111 and we're left with 111.
Bring next digit (9) of the dividend behind the 111 and repeat the process: 1119 / 338

On to step 6:
1119 divided by 338 is 3 with a remainder of 105.
Use 3 as the next digit of our solution. 
Result so far: 1503.0
Deduct 1014 from 1119 and we're left with 105.
Bring next digit (8) of the dividend behind the 105 and repeat the process: 1058 / 338

Step 7:
1058 divided by 338 is 3 with a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 15033.0
If we subtract 1014 from 1058, we get 44.
Grab the next digit (7) from the dividend, add it to 44, then carry on: 447 / 338

Going ahead to step 8:
338 can be fit into 447 1 times, resulting in a remainder of 109.
Write down 1 as next digit of the result. 
Result so far: 150331.0
Subtract 338 from 447 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 9:
1090 divided by 338 is 3 with a remainder of 76.
Write down 3 as next digit of the result. 
Result so far: 150331.3
Deduct 1014 from 1090 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 10:
If we divide 760 by 338, we get 2 and a remainder of 84.
Put 2 as the next digit of the answer. 
Result so far: 150331.32
Deduct 676 from 760 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 11:
338 can be fit into 840 2 times, resulting in a remainder of 164.
The next digit of our result is 2. 
Result so far: 150331.322
If we subtract 676 from 840, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

After the division, we end up with 150331.322 and a remainder of 0.0164.
