We're dividing 31629515 by 80 
We're looking to find how many times 80 goes into 31629515.

Going ahead to step 1:
80 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 80

Moving on to step 2:
80 goes into 31 0 times with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 80

Step 3:
The number 80 fits into 316 3 times, leaving a remainder of 76.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 240 away from 316, we end up with 76.
Grab the next digit (2) from the dividend, add it to 76, then carry on: 762 / 80

Let's proceed to step 4:
80 can be fit into 762 9 times, resulting in a remainder of 42.
The next digit of our result is 9. 
Result so far: 39.0
The remainder is 42 after subtracting 720 from 762.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 80

Moving on to step 5:
80 goes into 429 5 times with a remainder of 29.
Record the quotient 5 as the next digit in the result. 
Result so far: 395.0
If we subtract 400 from 429, we get 29.
Take the next digit (5) from the dividend and append it to 29, then repeat: 295 / 80

On to step 6:
When dividing 295 by 80, we get 3 with a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 3953.0
If we subtract 240 from 295, we get 55.
Include the next digit (1) from the dividend after 55, then repeat: 551 / 80

On to step 7:
If we divide 551 by 80, we get 6 and a remainder of 71.
Put 6 as the next digit of the answer. 
Result so far: 39536.0
If we subtract 480 from 551, we get 71.
Grab the next digit (5) from the dividend, add it to 71, then carry on: 715 / 80

Advancing to step 8:
715 divided by 80 is 8 with a remainder of 75.
Record the quotient 8 as the next digit in the result. 
Result so far: 395368.0
Subtracting 640 from 715 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 9:
The number 80 fits into 750 9 times, leaving a remainder of 30.
Write down 9 as next digit of the result. 
Result so far: 395368.9
If we subtract 720 from 750, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
80 goes into 300 3 times with a remainder of 60.
The next digit of our result is 3. 
Result so far: 395368.93
If we subtract 240 from 300, 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.

On to step 11:
If we divide 600 by 80, we get 7 and a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 395368.937
Subtract 560 from 600 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 12:
When dividing 400 by 80, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 395368.9375
If we subtract 400 from 400, 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.

Moving on to step 13:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 395368.9375
The remainder is 0 after subtracting 0 from 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 14:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 395368.9375
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.

The quotient of the division is 395368.9375, and the remainder is 0.0.
