We look at the division of 789991 by 89 
Our goal is to divide 789991 by 89.

Advancing to step 1:
When dividing 7 by 89, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 89

Step 2:
78 divided by 89 is 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Fetch the next digit (9) from the dividend, attach it to 78 and continue: 789 / 89

Advancing to step 3:
789 divided by 89 is 8 with a remainder of 77.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 712 from 789 and we're left with 77.
Fetch the next digit (9) from the dividend, attach it to 77 and continue: 779 / 89

Advancing to step 4:
The number 89 fits into 779 8 times, leaving a remainder of 67.
Write down 8 as next digit of the result. 
Result so far: 88.0
Deduct 712 from 779 and we're left with 67.
Bring next digit (9) of the dividend behind the 67 and repeat the process: 679 / 89

Step 5:
When dividing 679 by 89, we get 7 with a remainder of 56.
The next digit of our result is 7. 
Result so far: 887.0
Subtracting 623 from 679 leaves us with 56.
Take the next digit (1) from the dividend and append it to 56, then repeat: 561 / 89

Moving on to step 6:
561 divided by 89 is 6 with a remainder of 27.
Use 6 as the next digit of our solution. 
Result so far: 8876.0
If we take 534 away from 561, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
270 divided by 89 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 8876.3
Subtracting 267 from 270 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
When dividing 30 by 89, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 8876.3
Deduct 0 from 30 and we're left with 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 9:
89 goes into 300 3 times with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 8876.303
Deduct 267 from 300 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 10:
89 can be fit into 330 3 times, resulting in a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 8876.3033
Subtracting 267 from 330 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The quotient of the division is 8876.3033, and the remainder is 0.00063.
