We look at the division of 660709 by 89 
Our goal is to divide 660709 by 89.

Let's proceed to step 1:
If we divide 6 by 89, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 89

On to step 2:
66 divided by 89 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (0) from the dividend, attach it to 66 and continue: 660 / 89

On to step 3:
89 goes into 660 7 times with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 623 from 660, we get 37.
Bring next digit (7) of the dividend behind the 37 and repeat the process: 377 / 89

Step 4:
When dividing 377 by 89, we get 4 with a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 74.0
Subtract 356 from 377 to get 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 89

Going ahead to step 5:
89 goes into 210 2 times with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 742.0
If we subtract 178 from 210, we get 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 89

Going ahead to step 6:
89 goes into 329 3 times with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 7423.0
Subtract 267 from 329 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 7:
89 can be fit into 620 6 times, resulting in a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 7423.6
If we take 534 away from 620, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 8:
The number 89 fits into 860 9 times, leaving a remainder of 59.
The next digit of our result is 9. 
Result so far: 7423.69
If we subtract 801 from 860, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 9:
If we divide 590 by 89, we get 6 and a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 7423.696
Subtract 534 from 590 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
560 divided by 89 is 6 with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 7423.6966
If we subtract 534 from 560, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 7423.6966, with a leftover of 0.00026.
