64889 ÷ 90 
We want to divide 64889 by 90.

Let's proceed to step 1:
6 divided by 90 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 90

Moving on to step 2:
If we divide 64 by 90, we get 0 and a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 90

Advancing to step 3:
When dividing 648 by 90, we get 7 with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 630 from 648 leaves us with 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 90

Going ahead to step 4:
90 goes into 188 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 72.0
The remainder is 8 after subtracting 180 from 188.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 90

Let's proceed to step 5:
When dividing 89 by 90, we get 0 with a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 720.0
If we subtract 0 from 89, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 6:
890 divided by 90 is 9 with a remainder of 80.
Use 9 as the next digit of our solution. 
Result so far: 720.9
If we subtract 810 from 890, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 7:
When dividing 800 by 90, we get 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 720.98
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 8:
When dividing 800 by 90, we get 8 with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 720.988
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 720.988 with a remaining 0.008.
