339630 ÷ 80 
We're looking to find how many times 80 goes into 339630.

Advancing 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.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 80

Moving on to step 2:
80 can be fit into 33 0 times, resulting in a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Append the next digit (9) from the dividend to 33 and continue with: 339 / 80

Advancing to step 3:
80 can be fit into 339 4 times, resulting in a remainder of 19.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 320 from 339 and we're left with 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 80

Let's proceed to step 4:
The number 80 fits into 196 2 times, leaving a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Deduct 160 from 196 and we're left with 36.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 80

Let's proceed to step 5:
80 can be fit into 363 4 times, resulting in a remainder of 43.
Put 4 as the next digit of the answer. 
Result so far: 424.0
If we subtract 320 from 363, we get 43.
Fetch the next digit (0) from the dividend, attach it to 43 and continue: 430 / 80

Advancing to step 6:
The number 80 fits into 430 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 4245.0
Subtracting 400 from 430 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
80 goes into 300 3 times with a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 4245.3
Subtract 240 from 300 to get 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 8:
If we divide 600 by 80, we get 7 and a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 4245.37
Subtracting 560 from 600 leaves us with 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 9:
When dividing 400 by 80, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4245.375
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4245.375
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.

Advancing to step 11:
80 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4245.375
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.

The quotient of the division is 4245.375, and the remainder is 0.0.
