Let's divide 849851 by 80
Our goal is to divide 849851 by 80.

Step 1:
80 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 80

Going ahead to step 2:
80 goes into 84 1 times with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 80 away from 84, we end up with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 80

Going ahead to step 3:
The number 80 fits into 49 0 times, leaving a remainder of 49.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 49 after subtracting 0 from 49.
Take the next digit (8) from the dividend and append it to 49, then repeat: 498 / 80

Let's proceed to step 4:
If we divide 498 by 80, we get 6 and a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 106.0
The remainder is 18 after subtracting 480 from 498.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 80

Step 5:
When dividing 185 by 80, we get 2 with a remainder of 25.
The next digit of our result is 2. 
Result so far: 1062.0
Subtracting 160 from 185 leaves us with 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 80

Advancing to step 6:
If we divide 251 by 80, we get 3 and a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 10623.0
If we subtract 240 from 251, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
80 goes into 110 1 times with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 10623.1
Subtract 80 from 110 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
80 goes into 300 3 times with a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 10623.13
If we subtract 240 from 300, we 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.

Let's proceed to step 9:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 10623.137
The remainder is 40 after subtracting 560 from 600.
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:
80 goes into 400 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 10623.1375
Subtracting 400 from 400 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.

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: 10623.1375
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.

Let's proceed to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10623.1375
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.

Our division results in 10623.1375 with a remaining 0.0.
