We're dividing 353834 by 80 
Our goal is to divide 353834 by 80.

Step 1:
80 can be fit into 3 0 times, resulting in 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

On 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 subtract 0 from 35, we get 35.
Bring next digit (3) of the dividend behind the 35 and repeat the process: 353 / 80

On to step 3:
The number 80 fits into 353 4 times, leaving a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 320 from 353 and we're left with 33.
Fetch the next digit (8) from the dividend, attach it to 33 and continue: 338 / 80

Step 4:
When dividing 338 by 80, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Subtract 320 from 338 to get 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 80

Moving on to step 5:
80 can be fit into 183 2 times, resulting in a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 442.0
Deduct 160 from 183 and we're left with 23.
Fetch the next digit (4) from the dividend, attach it to 23 and continue: 234 / 80

Going ahead to step 6:
80 can be fit into 234 2 times, resulting in a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 4422.0
The remainder is 74 after subtracting 160 from 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 7:
When dividing 740 by 80, we get 9 with a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 4422.9
The remainder is 20 after subtracting 720 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
The number 80 fits into 200 2 times, leaving a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 4422.92
The remainder is 40 after subtracting 160 from 200.
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 9:
If we divide 400 by 80, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4422.925
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.

On to step 10:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4422.925
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.

Step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4422.925
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 quotient of the division is 4422.925, and the remainder is 0.0.
