51262758 divided by 339 
Our goal is to divide 51262758 by 339.

On to step 1:
If we divide 5 by 339, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 339

On to step 2:
339 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Bring next digit (2) of the dividend behind the 51 and repeat the process: 512 / 339

On to step 3:
512 divided by 339 is 1 with a remainder of 173.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 339 from 512 to get 173.
Grab the next digit (6) from the dividend, add it to 173, then carry on: 1736 / 339

Going ahead to step 4:
1736 divided by 339 is 5 with a remainder of 41.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 1695 away from 1736, we end up with 41.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 339

Moving on to step 5:
412 divided by 339 is 1 with a remainder of 73.
The next digit of our result is 1. 
Result so far: 151.0
Deduct 339 from 412 and we're left with 73.
Bring next digit (7) of the dividend behind the 73 and repeat the process: 737 / 339

Advancing to step 6:
339 goes into 737 2 times with a remainder of 59.
The next digit of our result is 2. 
Result so far: 1512.0
If we take 678 away from 737, we end up with 59.
Grab the next digit (5) from the dividend, add it to 59, then carry on: 595 / 339

Let's proceed to step 7:
339 goes into 595 1 times with a remainder of 256.
Use 1 as the next digit of our solution. 
Result so far: 15121.0
If we take 339 away from 595, we end up with 256.
Append the next digit (8) from the dividend to 256 and continue with: 2568 / 339

Let's proceed to step 8:
If we divide 2568 by 339, we get 7 and a remainder of 195.
Write down 7 as next digit of the result. 
Result so far: 151217.0
Subtracting 2373 from 2568 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Going ahead to step 9:
The number 339 fits into 1950 5 times, leaving a remainder of 255.
Record the quotient 5 as the next digit in the result. 
Result so far: 151217.5
Subtracting 1695 from 1950 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 10:
339 goes into 2550 7 times with a remainder of 177.
Record the quotient 7 as the next digit in the result. 
Result so far: 151217.57
Deduct 2373 from 2550 and we're left with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Going ahead to step 11:
1770 divided by 339 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 151217.575
Subtract 1695 from 1770 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 12:
If we divide 750 by 339, we get 2 and a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 151217.5752
Subtracting 678 from 750 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 13:
339 goes into 720 2 times with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 151217.57522
Deduct 678 from 720 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 151217.57522, with a leftover of 4.2e-05.
