64686 ÷ 50 
We're looking to find how many times 50 goes into 64686.

Going ahead to step 1:
6 divided by 50 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 50

Going ahead to step 2:
50 can be fit into 64 1 times, resulting in a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 14 after subtracting 50 from 64.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 50

Let's proceed to step 3:
The number 50 fits into 146 2 times, leaving a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 100 from 146 and we're left with 46.
Fetch the next digit (8) from the dividend, attach it to 46 and continue: 468 / 50

Let's proceed to step 4:
50 goes into 468 9 times with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
Subtracting 450 from 468 leaves us with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 50

Moving on to step 5:
When dividing 186 by 50, we get 3 with a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 1293.0
If we take 150 away from 186, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 6:
If we divide 360 by 50, we get 7 and a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 1293.7
Subtract 350 from 360 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
The number 50 fits into 100 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 1293.72
If we subtract 100 from 100, we 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.

Let's proceed to step 8:
When dividing 0 by 50, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1293.72
If we subtract 0 from 0, we 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.

Going ahead to step 9:
If we divide 0 by 50, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1293.72
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.

The final outcome is 1293.72, with a leftover of 0.0.
