We look at the division of 356315 by 80 
We're looking to find how many times 80 goes into 356315.

Going ahead to step 1:
When dividing 3 by 80, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 80

Moving on to step 2:
The number 80 fits into 35 0 times, leaving a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Bring next digit (6) of the dividend behind the 35 and repeat the process: 356 / 80

On to step 3:
If we divide 356 by 80, we get 4 and a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 36 after subtracting 320 from 356.
Fetch the next digit (3) from the dividend, attach it to 36 and continue: 363 / 80

Step 4:
80 can be fit into 363 4 times, resulting in a remainder of 43.
The next digit of our result is 4. 
Result so far: 44.0
Subtract 320 from 363 to get 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 80

Let's proceed to step 5:
80 goes into 431 5 times with a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 445.0
Subtract 400 from 431 to get 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 80

Advancing to step 6:
315 divided by 80 is 3 with a remainder of 75.
The next digit of our result is 3. 
Result so far: 4453.0
Subtracting 240 from 315 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 7:
When dividing 750 by 80, we get 9 with a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 4453.9
Deduct 720 from 750 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
When dividing 300 by 80, we get 3 with a remainder of 60.
The next digit of our result is 3. 
Result so far: 4453.93
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 9:
80 goes into 600 7 times with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 4453.937
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.

Going ahead 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: 4453.9375
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.

Let's proceed to step 11:
80 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4453.9375
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.

Advancing to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4453.9375
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.

After the division, we end up with 4453.9375 and a remainder of 0.0.
