We look at the division of 891230 by 80 
We're looking to find how many times 80 goes into 891230.

Advancing to step 1:
80 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 80

Let's proceed to step 2:
89 divided by 80 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 80 from 89 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 80

Let's proceed to step 3:
The number 80 fits into 91 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 80 from 91 and we're left with 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 80

Step 4:
When dividing 112 by 80, we get 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 111.0
Subtract 80 from 112 to get 32.
Append the next digit (3) from the dividend to 32 and continue with: 323 / 80

Step 5:
80 can be fit into 323 4 times, resulting in a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 1114.0
If we take 320 away from 323, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 80

Moving on to step 6:
30 divided by 80 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 11140.0
Subtract 0 from 30 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.

Let's proceed to step 7:
The number 80 fits into 300 3 times, leaving a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 11140.3
Deduct 240 from 300 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.

Going ahead to step 8:
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: 11140.37
Deduct 560 from 600 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.

Step 9:
400 divided by 80 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 11140.375
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.

Going ahead to step 10:
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: 11140.375
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.

Advancing to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 11140.375
Subtract 0 from 0 to 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 quotient of the division is 11140.375, and the remainder is 0.0.
