Let's divide 689123 by 89
Let's see how many times 89 fits into 689123.

Going ahead to step 1:
89 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 89

On to step 2:
68 divided by 89 is 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Grab the next digit (9) from the dividend, add it to 68, then carry on: 689 / 89

Step 3:
89 goes into 689 7 times with a remainder of 66.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 623 from 689, we get 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 89

Step 4:
89 can be fit into 661 7 times, resulting in a remainder of 38.
The next digit of our result is 7. 
Result so far: 77.0
Subtracting 623 from 661 leaves us with 38.
Include the next digit (2) from the dividend after 38, then repeat: 382 / 89

Moving on to step 5:
89 goes into 382 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 774.0
Subtract 356 from 382 to get 26.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 89

On to step 6:
When dividing 263 by 89, we get 2 with a remainder of 85.
Record the quotient 2 as the next digit in the result. 
Result so far: 7742.0
Subtract 178 from 263 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 7:
The number 89 fits into 850 9 times, leaving a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 7742.9
Subtracting 801 from 850 leaves us 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.

Moving on to step 8:
89 can be fit into 490 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 7742.95
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.

Moving on to step 9:
If we divide 450 by 89, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 7742.955
Subtracting 445 from 450 leaves us with 5.
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 result is 7742.955 with a remainder of 0.0005.
