686631 divided by 89 
We want to figure out the number of times 686631 can be divided by 89.

Let's proceed to step 1:
6 divided by 89 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 89

Step 2:
When dividing 68 by 89, we get 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Grab the next digit (6) from the dividend, add it to 68, then carry on: 686 / 89

Step 3:
686 divided by 89 is 7 with a remainder of 63.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 623 from 686, we get 63.
Take the next digit (6) from the dividend and append it to 63, then repeat: 636 / 89

Moving on to step 4:
If we divide 636 by 89, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
Deduct 623 from 636 and we're left with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 89

Moving on to step 5:
89 can be fit into 133 1 times, resulting in a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 771.0
Deduct 89 from 133 and we're left with 44.
Bring next digit (1) of the dividend behind the 44 and repeat the process: 441 / 89

On to step 6:
89 goes into 441 4 times with a remainder of 85.
The next digit of our result is 4. 
Result so far: 7714.0
If we take 356 away from 441, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 7:
850 divided by 89 is 9 with a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 7714.9
If we take 801 away from 850, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 8:
The number 89 fits into 490 5 times, leaving a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 7714.95
Subtract 445 from 490 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 9:
When dividing 450 by 89, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 7714.955
The remainder is 5 after subtracting 445 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 7714.955, with a leftover of 0.0005.
