We divide 920639 by 50
We're looking to find how many times 50 goes into 920639.

Going ahead to step 1:
9 divided by 50 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 50

On to step 2:
The number 50 fits into 92 1 times, leaving a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 50 from 92, we get 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 50

Step 3:
420 divided by 50 is 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 400 from 420 leaves us with 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 50

Moving on to step 4:
50 goes into 206 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 184.0
Subtract 200 from 206 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 50

Let's proceed to step 5:
The number 50 fits into 63 1 times, leaving a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1841.0
Deduct 50 from 63 and we're left with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 50

Let's proceed to step 6:
The number 50 fits into 139 2 times, leaving a remainder of 39.
Put 2 as the next digit of the answer. 
Result so far: 18412.0
Deduct 100 from 139 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 7:
50 can be fit into 390 7 times, resulting in a remainder of 40.
The next digit of our result is 7. 
Result so far: 18412.7
If we take 350 away from 390, 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.

Going ahead to step 8:
When dividing 400 by 50, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 18412.78
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.

On to step 9:
If we divide 0 by 50, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 18412.78
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.

Going ahead to step 10:
50 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 18412.78
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.

After the division, we end up with 18412.78 and a remainder of 0.0.
