Let's divide 353560 by 80
Let's see how many times 80 fits into 353560.

Let's proceed to step 1:
When dividing 3 by 80, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 80

Going ahead to step 2:
80 goes into 35 0 times with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Append the next digit (3) from the dividend to 35 and continue with: 353 / 80

Let's proceed to step 3:
80 can be fit into 353 4 times, resulting in a remainder of 33.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 320 from 353, we get 33.
Fetch the next digit (5) from the dividend, attach it to 33 and continue: 335 / 80

On to step 4:
80 goes into 335 4 times with a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Subtract 320 from 335 to get 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 80

Moving on to step 5:
156 divided by 80 is 1 with a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 441.0
Deduct 80 from 156 and we're left with 76.
Fetch the next digit (0) from the dividend, attach it to 76 and continue: 760 / 80

Step 6:
760 divided by 80 is 9 with a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 4419.0
If we subtract 720 from 760, we 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.

Going ahead to step 7:
400 divided by 80 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4419.5
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.

Let's proceed to step 8:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4419.5
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.

Going ahead to step 9:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4419.5
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.

The final outcome is 4419.5, with a leftover of 0.0.
