688340 ÷ 50 
We're looking to find how many times 50 goes into 688340.

Advancing to step 1:
The number 50 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 50

Step 2:
50 goes into 68 1 times with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 18 after subtracting 50 from 68.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 50

Going ahead to step 3:
The number 50 fits into 188 3 times, leaving a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 150 from 188 leaves us with 38.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 50

Step 4:
If we divide 383 by 50, we get 7 and a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 137.0
The remainder is 33 after subtracting 350 from 383.
Grab the next digit (4) from the dividend, add it to 33, then carry on: 334 / 50

Advancing to step 5:
50 can be fit into 334 6 times, resulting in a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 1376.0
Subtract 300 from 334 to get 34.
Append the next digit (0) from the dividend to 34 and continue with: 340 / 50

Moving on to step 6:
When dividing 340 by 50, we get 6 with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 13766.0
If we take 300 away from 340, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
The number 50 fits into 400 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 13766.8
Deduct 400 from 400 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
When dividing 0 by 50, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13766.8
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 50 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13766.8
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 13766.8 and a remainder of 0.0.
