355486 ÷ 50 
We want to figure out the number of times 355486 can be divided by 50.

Advancing to step 1:
3 divided by 50 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 50

Moving on to step 2:
The number 50 fits into 35 0 times, leaving a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 50

On to step 3:
355 divided by 50 is 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 5 after subtracting 350 from 355.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 50

Moving on to step 4:
If we divide 54 by 50, we get 1 and a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 71.0
If we subtract 50 from 54, we get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 50

Step 5:
The number 50 fits into 48 0 times, leaving a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 710.0
If we subtract 0 from 48, we get 48.
Include the next digit (6) from the dividend after 48, then repeat: 486 / 50

Moving on to step 6:
If we divide 486 by 50, we get 9 and a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 7109.0
If we take 450 away from 486, 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.

On to step 7:
50 goes into 360 7 times with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 7109.7
If we take 350 away from 360, we end up with 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 8:
50 goes into 100 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 7109.72
If we take 100 away from 100, 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.

Step 9:
0 divided by 50 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7109.72
If we take 0 away from 0, 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.

On to step 10:
0 divided by 50 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7109.72
If we take 0 away from 0, 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.

The final outcome is 7109.72, with a leftover of 0.0.
