321910 ÷ 50 
Let's see how many times 50 fits into 321910.

On to step 1:
The number 50 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 50

Going ahead to step 2:
The number 50 fits into 32 0 times, leaving a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 50

On to step 3:
50 goes into 321 6 times with a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 300 from 321 and we're left with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 50

On to step 4:
If we divide 219 by 50, we get 4 and a remainder of 19.
The next digit of our result is 4. 
Result so far: 64.0
Deduct 200 from 219 and we're left with 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 50

Advancing to step 5:
191 divided by 50 is 3 with a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 643.0
The remainder is 41 after subtracting 150 from 191.
Bring next digit (0) of the dividend behind the 41 and repeat the process: 410 / 50

Step 6:
The number 50 fits into 410 8 times, leaving a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 6438.0
If we subtract 400 from 410, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
50 goes into 100 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 6438.2
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.

Going ahead to step 8:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6438.2
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.

Advancing to step 9:
50 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6438.2
Deduct 0 from 0 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.

The final outcome is 6438.2, with a leftover of 0.0.
