We're dividing 51228 by 80 
Let's see how many times 80 fits into 51228.

On to step 1:
If we divide 5 by 80, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 80

On to step 2:
80 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (2) from the dividend and append it to 51, then repeat: 512 / 80

Moving on to step 3:
When dividing 512 by 80, we get 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 32 after subtracting 480 from 512.
Bring next digit (2) of the dividend behind the 32 and repeat the process: 322 / 80

Going ahead to step 4:
80 can be fit into 322 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
If we subtract 320 from 322, we get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 80

Going ahead to step 5:
The number 80 fits into 28 0 times, leaving a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 640.0
If we take 0 away from 28, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 6:
80 can be fit into 280 3 times, resulting in a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 640.3
Subtract 240 from 280 to get 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 7:
If we divide 400 by 80, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 640.35
Subtract 400 from 400 to 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 8:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 640.35
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.

On to step 9:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 640.35
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.

Our division results in 640.35 with a remaining 0.0.
