Let's divide 399099 by 50
We're looking to find how many times 50 goes into 399099.

Going ahead to step 1:
When dividing 3 by 50, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 50

On to step 2:
50 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 50

Step 3:
399 divided by 50 is 7 with a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 350 from 399, we get 49.
Bring next digit (0) of the dividend behind the 49 and repeat the process: 490 / 50

Step 4:
When dividing 490 by 50, we get 9 with a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 79.0
The remainder is 40 after subtracting 450 from 490.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 50

Moving on to step 5:
50 can be fit into 409 8 times, resulting in a remainder of 9.
The next digit of our result is 8. 
Result so far: 798.0
The remainder is 9 after subtracting 400 from 409.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 50

Moving on to step 6:
When dividing 99 by 50, we get 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 7981.0
If we subtract 50 from 99, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
490 divided by 50 is 9 with a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 7981.9
If we take 450 away from 490, 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.

Advancing to step 8:
When dividing 400 by 50, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 7981.98
If we subtract 400 from 400, 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.

Moving on to step 9:
When dividing 0 by 50, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7981.98
Subtracting 0 from 0 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.

On to step 10:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7981.98
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.

Our division results in 7981.98 with a remaining 0.0.
