We look at the division of 770809 by 89 
Our goal is to divide 770809 by 89.

On to step 1:
7 divided by 89 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 89

Going ahead to step 2:
The number 89 fits into 77 0 times, leaving a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Include the next digit (0) from the dividend after 77, then repeat: 770 / 89

Let's proceed to step 3:
If we divide 770 by 89, we get 8 and a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 712 from 770 to get 58.
Take the next digit (8) from the dividend and append it to 58, then repeat: 588 / 89

Moving on to step 4:
89 goes into 588 6 times with a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 86.0
If we subtract 534 from 588, we get 54.
Append the next digit (0) from the dividend to 54 and continue with: 540 / 89

Let's proceed to step 5:
When dividing 540 by 89, we get 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 866.0
Deduct 534 from 540 and we're left with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 89

Advancing to step 6:
When dividing 69 by 89, we get 0 with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 8660.0
Deduct 0 from 69 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 7:
When dividing 690 by 89, we get 7 with a remainder of 67.
Put 7 as the next digit of the answer. 
Result so far: 8660.7
Subtracting 623 from 690 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 8:
The number 89 fits into 670 7 times, leaving a remainder of 47.
The next digit of our result is 7. 
Result so far: 8660.77
Subtracting 623 from 670 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

After the division, we end up with 8660.77 and a remainder of 0.047.
