945879 ÷ 80 
Let's see how many times 80 fits into 945879.

On to step 1:
80 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 80

Advancing to step 2:
80 can be fit into 94 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 80 from 94, we get 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 80

Moving on to step 3:
If we divide 145 by 80, we get 1 and a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 80 away from 145, we end up with 65.
Append the next digit (8) from the dividend to 65 and continue with: 658 / 80

Step 4:
If we divide 658 by 80, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 118.0
If we take 640 away from 658, we end up with 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 80

Step 5:
80 goes into 187 2 times with a remainder of 27.
The next digit of our result is 2. 
Result so far: 1182.0
Subtracting 160 from 187 leaves us with 27.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 80

Advancing to step 6:
If we divide 279 by 80, we get 3 and a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 11823.0
Deduct 240 from 279 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
If we divide 390 by 80, we get 4 and a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 11823.4
Deduct 320 from 390 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
If we divide 700 by 80, we get 8 and a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 11823.48
If we subtract 640 from 700, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
The next digit of our result is 7. 
Result so far: 11823.487
Subtracting 560 from 600 leaves us 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.

Let's proceed to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 11823.4875
Subtracting 400 from 400 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.

Advancing to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 11823.4875
Subtract 0 from 0 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.

Step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11823.4875
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.

After the division, we end up with 11823.4875 and a remainder of 0.0.
