We look at the division of 347642 by 80 
Let's see how many times 80 fits into 347642.

On to step 1:
If we divide 3 by 80, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 80

Going ahead to step 2:
If we divide 34 by 80, we get 0 and a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Grab the next digit (7) from the dividend, add it to 34, then carry on: 347 / 80

Let's proceed to step 3:
347 divided by 80 is 4 with a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 320 from 347 to get 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 80

Step 4:
The number 80 fits into 276 3 times, leaving a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we take 240 away from 276, we end up with 36.
Append the next digit (4) from the dividend to 36 and continue with: 364 / 80

Moving on to step 5:
If we divide 364 by 80, we get 4 and a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 434.0
If we subtract 320 from 364, we get 44.
Take the next digit (2) from the dividend and append it to 44, then repeat: 442 / 80

Advancing to step 6:
If we divide 442 by 80, we get 5 and a remainder of 42.
Record the quotient 5 as the next digit in the result. 
Result so far: 4345.0
If we subtract 400 from 442, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 7:
When dividing 420 by 80, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 4345.5
Subtracting 400 from 420 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
200 divided by 80 is 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 4345.52
Subtract 160 from 200 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.

Step 9:
400 divided by 80 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4345.525
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.

Advancing to step 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4345.525
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.

On to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4345.525
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.

Our division results in 4345.525 with a remaining 0.0.
