We divide 353454 by 80
We want to divide 353454 by 80.

Step 1:
If we divide 3 by 80, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
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

Advancing to step 2:
The number 80 fits into 35 0 times, leaving a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Fetch the next digit (3) from the dividend, attach it to 35 and continue: 353 / 80

Advancing to step 3:
353 divided by 80 is 4 with a remainder of 33.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 320 from 353 leaves us with 33.
Fetch the next digit (4) from the dividend, attach it to 33 and continue: 334 / 80

Step 4:
334 divided by 80 is 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 44.0
The remainder is 14 after subtracting 320 from 334.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 80

Going ahead to step 5:
145 divided by 80 is 1 with a remainder of 65.
The next digit of our result is 1. 
Result so far: 441.0
Subtracting 80 from 145 leaves us with 65.
Append the next digit (4) from the dividend to 65 and continue with: 654 / 80

Advancing to step 6:
When dividing 654 by 80, we get 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 4418.0
Deduct 640 from 654 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
80 can be fit into 140 1 times, resulting in a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 4418.1
Deduct 80 from 140 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
When dividing 600 by 80, we get 7 with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 4418.17
The remainder is 40 after subtracting 560 from 600.
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 9:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 4418.175
Deduct 400 from 400 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.

Advancing to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4418.175
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.

Step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4418.175
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.

In conclusion, the division gives 4418.175 with a balance of 0.0.
