We're dividing 31685883 by 80 
Let's see how many times 80 fits into 31685883.

Going ahead to step 1:
3 divided by 80 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 80

Moving on to step 2:
80 goes into 31 0 times with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 80

Step 3:
316 divided by 80 is 3 with a remainder of 76.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 240 away from 316, we end up with 76.
Bring next digit (8) of the dividend behind the 76 and repeat the process: 768 / 80

On to step 4:
80 goes into 768 9 times with a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we subtract 720 from 768, we get 48.
Bring next digit (5) of the dividend behind the 48 and repeat the process: 485 / 80

Going ahead to step 5:
80 goes into 485 6 times with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 396.0
Subtracting 480 from 485 leaves us with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 80

Step 6:
The number 80 fits into 58 0 times, leaving a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 3960.0
If we take 0 away from 58, we end up with 58.
Bring next digit (8) of the dividend behind the 58 and repeat the process: 588 / 80

On to step 7:
The number 80 fits into 588 7 times, leaving a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 39607.0
Subtract 560 from 588 to get 28.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 80

Advancing to step 8:
If we divide 283 by 80, we get 3 and a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 396073.0
If we subtract 240 from 283, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
When dividing 430 by 80, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 396073.5
The remainder is 30 after subtracting 400 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
300 divided by 80 is 3 with a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 396073.53
Subtract 240 from 300 to 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 11:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 396073.537
Deduct 560 from 600 and we're left 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 12:
80 can be fit into 400 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 396073.5375
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.

Advancing to step 13:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 396073.5375
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.

On to step 14:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 396073.5375
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.

The quotient of the division is 396073.5375, and the remainder is 0.0.
