Let's divide 68279212 by 80
We want to divide 68279212 by 80.

Step 1:
The number 80 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 80

Moving on to step 2:
68 divided by 80 is 0 with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Take the next digit (2) from the dividend and append it to 68, then repeat: 682 / 80

Going ahead to step 3:
When dividing 682 by 80, we get 8 with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 640 away from 682, we end up with 42.
Append the next digit (7) from the dividend to 42 and continue with: 427 / 80

On to step 4:
If we divide 427 by 80, we get 5 and a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
Subtracting 400 from 427 leaves us with 27.
Append the next digit (9) from the dividend to 27 and continue with: 279 / 80

Step 5:
279 divided by 80 is 3 with a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 853.0
Deduct 240 from 279 and we're left with 39.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 80

Moving on to step 6:
80 goes into 392 4 times with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 8534.0
If we subtract 320 from 392, we get 72.
Append the next digit (1) from the dividend to 72 and continue with: 721 / 80

Moving on to step 7:
721 divided by 80 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 85349.0
If we subtract 720 from 721, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 80

Advancing to step 8:
12 divided by 80 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 853490.0
If we take 0 away from 12, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
80 goes into 120 1 times with a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 853490.1
If we take 80 away from 120, 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.

Moving on to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 853490.15
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 11:
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: 853490.15
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.

Let's proceed to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 853490.15
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 853490.15 and a remainder of 0.0.
