33742 divided by 80 
We're looking to find how many times 80 goes into 33742.

On 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
Subtract 0 from 3 to get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 80

Moving on to step 2:
80 goes into 33 0 times with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Take the next digit (7) from the dividend and append it to 33, then repeat: 337 / 80

Going ahead to step 3:
If we divide 337 by 80, we get 4 and a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 320 from 337 leaves us with 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 80

Step 4:
The number 80 fits into 174 2 times, leaving a remainder of 14.
The next digit of our result is 2. 
Result so far: 42.0
The remainder is 14 after subtracting 160 from 174.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 80

Moving on to step 5:
If we divide 142 by 80, we get 1 and a remainder of 62.
The next digit of our result is 1. 
Result so far: 421.0
The remainder is 62 after subtracting 80 from 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 6:
When dividing 620 by 80, we get 7 with a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 421.7
Deduct 560 from 620 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.

On to step 7:
600 divided by 80 is 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 421.77
Subtract 560 from 600 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.

After the division, we end up with 421.77 and a remainder of 0.04.
