603841 ÷ 80 
We want to figure out the number of times 603841 can be divided by 80.

Moving on to step 1:
6 divided by 80 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 80

On to step 2:
80 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 60 to get 60.
Bring next digit (3) of the dividend behind the 60 and repeat the process: 603 / 80

Let's proceed to step 3:
If we divide 603 by 80, we get 7 and a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 560 from 603 and we're left with 43.
Fetch the next digit (8) from the dividend, attach it to 43 and continue: 438 / 80

Going ahead to step 4:
If we divide 438 by 80, we get 5 and a remainder of 38.
Write down 5 as next digit of the result. 
Result so far: 75.0
The remainder is 38 after subtracting 400 from 438.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 80

Going ahead to step 5:
80 can be fit into 384 4 times, resulting in a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 754.0
Subtract 320 from 384 to get 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 80

On to step 6:
641 divided by 80 is 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 7548.0
Deduct 640 from 641 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
The number 80 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 7548.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 80, we get 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 7548.01
If we subtract 80 from 100, we get 20.
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 9:
If we divide 200 by 80, we get 2 and a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 7548.012
Deduct 160 from 200 and we're left 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.

Let's proceed 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: 7548.0125
If we take 400 away from 400, 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.

Step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7548.0125
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.

Going ahead to step 12:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7548.0125
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 7548.0125 with a remaining 0.0.
