We're dividing 384739 by 80 
We want to figure out the number of times 384739 can be divided by 80.

Going ahead to step 1:
If we divide 3 by 80, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 80

Moving on to step 2:
The number 80 fits into 38 0 times, leaving a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 80

Moving on to step 3:
80 can be fit into 384 4 times, resulting in a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 320 from 384, we get 64.
Append the next digit (7) from the dividend to 64 and continue with: 647 / 80

Moving on to step 4:
80 goes into 647 8 times with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Subtract 640 from 647 to get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 80

Step 5:
80 goes into 73 0 times with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 480.0
Deduct 0 from 73 and we're left with 73.
Bring next digit (9) of the dividend behind the 73 and repeat the process: 739 / 80

Moving on to step 6:
If we divide 739 by 80, we get 9 and a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 4809.0
The remainder is 19 after subtracting 720 from 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
If we divide 190 by 80, we get 2 and a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 4809.2
The remainder is 30 after subtracting 160 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
80 goes into 300 3 times with a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 4809.23
The remainder is 60 after subtracting 240 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
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: 4809.237
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.

Going ahead to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4809.2375
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 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4809.2375
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.

On to step 12:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4809.2375
If we subtract 0 from 0, 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.

The final result is 4809.2375 with a remainder of 0.0.
