We're dividing 357099 by 50 
Let's see how many times 50 fits into 357099.

Going ahead to step 1:
If we divide 3 by 50, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 50

On to step 2:
If we divide 35 by 50, we get 0 and a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Grab the next digit (7) from the dividend, add it to 35, then carry on: 357 / 50

Advancing to step 3:
If we divide 357 by 50, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 350 from 357 leaves us with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 50

Step 4:
50 goes into 70 1 times with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
If we subtract 50 from 70, we get 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 50

Moving on to step 5:
209 divided by 50 is 4 with a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 714.0
Subtract 200 from 209 to get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 50

On to step 6:
If we divide 99 by 50, we get 1 and a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 7141.0
If we take 50 away from 99, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
50 goes into 490 9 times with a remainder of 40.
The next digit of our result is 9. 
Result so far: 7141.9
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.

Step 8:
The number 50 fits into 400 8 times, leaving a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 7141.98
If we take 400 away from 400, we end up 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.

Advancing to step 9:
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: 7141.98
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7141.98
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.

After the division, we end up with 7141.98 and a remainder of 0.0.
