We look at the division of 84123222 by 50 
We're looking to find how many times 50 goes into 84123222.

On to step 1:
8 divided by 50 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 50

On to step 2:
The number 50 fits into 84 1 times, leaving a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 34 after subtracting 50 from 84.
Fetch the next digit (1) from the dividend, attach it to 34 and continue: 341 / 50

Step 3:
The number 50 fits into 341 6 times, leaving a remainder of 41.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 300 away from 341, we end up with 41.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 50

Let's proceed to step 4:
412 divided by 50 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 168.0
Subtracting 400 from 412 leaves us with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 50

Moving on to step 5:
50 can be fit into 123 2 times, resulting in a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 1682.0
Subtracting 100 from 123 leaves us with 23.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 50

On to step 6:
The number 50 fits into 232 4 times, leaving a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 16824.0
Subtract 200 from 232 to get 32.
Grab the next digit (2) from the dividend, add it to 32, then carry on: 322 / 50

Let's proceed to step 7:
50 can be fit into 322 6 times, resulting in a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 168246.0
Subtracting 300 from 322 leaves us with 22.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 50

On to step 8:
50 can be fit into 222 4 times, resulting in a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 1682464.0
The remainder is 22 after subtracting 200 from 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
50 can be fit into 220 4 times, resulting in a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 1682464.4
Subtracting 200 from 220 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
The number 50 fits into 200 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 1682464.44
If we subtract 200 from 200, 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 1682464.44 with a remaining 0.0.
