We're dividing 80899085 by 689 
We want to figure out the number of times 80899085 can be divided by 689.

Step 1:
The number 689 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 689

Advancing to step 2:
689 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Append the next digit (8) from the dividend to 80 and continue with: 808 / 689

Moving on to step 3:
689 goes into 808 1 times with a remainder of 119.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 689 from 808, we get 119.
Bring next digit (9) of the dividend behind the 119 and repeat the process: 1199 / 689

On to step 4:
689 goes into 1199 1 times with a remainder of 510.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 689 from 1199 leaves us with 510.
Bring next digit (9) of the dividend behind the 510 and repeat the process: 5109 / 689

Going ahead to step 5:
The number 689 fits into 5109 7 times, leaving a remainder of 286.
Use 7 as the next digit of our solution. 
Result so far: 117.0
Deduct 4823 from 5109 and we're left with 286.
Include the next digit (0) from the dividend after 286, then repeat: 2860 / 689

Moving on to step 6:
2860 divided by 689 is 4 with a remainder of 104.
The next digit of our result is 4. 
Result so far: 1174.0
Subtracting 2756 from 2860 leaves us with 104.
Include the next digit (8) from the dividend after 104, then repeat: 1048 / 689

Advancing to step 7:
The number 689 fits into 1048 1 times, leaving a remainder of 359.
Use 1 as the next digit of our solution. 
Result so far: 11741.0
Deduct 689 from 1048 and we're left with 359.
Fetch the next digit (5) from the dividend, attach it to 359 and continue: 3595 / 689

Step 8:
When dividing 3595 by 689, we get 5 with a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 117415.0
If we subtract 3445 from 3595, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 9:
The number 689 fits into 1500 2 times, leaving a remainder of 122.
Write down 2 as next digit of the result. 
Result so far: 117415.2
If we take 1378 away from 1500, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 10:
689 can be fit into 1220 1 times, resulting in a remainder of 531.
Put 1 as the next digit of the answer. 
Result so far: 117415.21
Subtract 689 from 1220 to get 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Going ahead to step 11:
5310 divided by 689 is 7 with a remainder of 487.
The next digit of our result is 7. 
Result so far: 117415.217
The remainder is 487 after subtracting 4823 from 5310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Step 12:
If we divide 4870 by 689, we get 7 and a remainder of 47.
The next digit of our result is 7. 
Result so far: 117415.2177
Subtract 4823 from 4870 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The quotient of the division is 117415.2177, and the remainder is 0.00047.
