Let's divide 636890 by 50
We want to figure out the number of times 636890 can be divided by 50.

Going ahead to step 1:
6 divided by 50 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 50

On to step 2:
When dividing 63 by 50, we get 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 50 away from 63, we end up with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 50

Advancing to step 3:
50 can be fit into 136 2 times, resulting in a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 100 away from 136, we end up with 36.
Append the next digit (8) from the dividend to 36 and continue with: 368 / 50

Advancing to step 4:
368 divided by 50 is 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 127.0
If we take 350 away from 368, we end up with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 50

Advancing to step 5:
50 can be fit into 189 3 times, resulting in a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 1273.0
If we subtract 150 from 189, we get 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 50

Advancing to step 6:
390 divided by 50 is 7 with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 12737.0
Deduct 350 from 390 and we're left 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 7:
400 divided by 50 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 12737.8
Subtracting 400 from 400 leaves us 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.
Use 0 as the next digit of our solution. 
Result so far: 12737.8
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.

On to step 9:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12737.8
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.

The final outcome is 12737.8, with a leftover of 0.0.
