When dividing 9 by 685, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 685

Advancing to step 2:
685 can be fit into 91 0 times, resulting in a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Include the next digit (2) from the dividend after 91, then repeat: 912 / 685

Moving on to step 3:
685 goes into 912 1 times with a remainder of 227.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 227 after subtracting 685 from 912.
Include the next digit (8) from the dividend after 227, then repeat: 2278 / 685

Moving on to step 4:
When dividing 2278 by 685, we get 3 with a remainder of 223.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 2055 from 2278 to get 223.
Fetch the next digit (7) from the dividend, attach it to 223 and continue: 2237 / 685

Step 5:
The number 685 fits into 2237 3 times, leaving a remainder of 182.
Use 3 as the next digit of our solution. 
Result so far: 133.0
If we take 2055 away from 2237, we end up with 182.
Take the next digit (8) from the dividend and append it to 182, then repeat: 1828 / 685

Going ahead to step 6:
The number 685 fits into 1828 2 times, leaving a remainder of 458.
Record the quotient 2 as the next digit in the result. 
Result so far: 1332.0
Subtracting 1370 from 1828 leaves us with 458.
Fetch the next digit (8) from the dividend, attach it to 458 and continue: 4588 / 685

Moving on to step 7:
When dividing 4588 by 685, we get 6 with a remainder of 478.
The number 6 becomes the next digit in our result. 
Result so far: 13326.0
If we take 4110 away from 4588, we end up with 478.
Include the next digit (3) from the dividend after 478, then repeat: 4783 / 685

Moving on to step 8:
4783 divided by 685 is 6 with a remainder of 673.
Use 6 as the next digit of our solution. 
Result so far: 133266.0
If we subtract 4110 from 4783, we get 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6730, and continue the process.

Going ahead to step 9:
6730 divided by 685 is 9 with a remainder of 565.
The number 9 becomes the next digit in our result. 
Result so far: 133266.9
If we take 6165 away from 6730, we end up with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

On to step 10:
When dividing 5650 by 685, we get 8 with a remainder of 170.
Put 8 as the next digit of the answer. 
Result so far: 133266.98
If we subtract 5480 from 5650, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 11:
The number 685 fits into 1700 2 times, leaving a remainder of 330.
Use 2 as the next digit of our solution. 
Result so far: 133266.982
Deduct 1370 from 1700 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 12:
685 can be fit into 3300 4 times, resulting in a remainder of 560.
Write down 4 as next digit of the result. 
Result so far: 133266.9824
Subtracting 2740 from 3300 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 13:
The number 685 fits into 5600 8 times, leaving a remainder of 120.
The next digit of our result is 8. 
Result so far: 133266.98248
Subtract 5480 from 5600 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 14:
685 can be fit into 1200 1 times, resulting in a remainder of 515.
The next digit of our result is 1. 
Result so far: 133266.982481
Subtract 685 from 1200 to get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Advancing to step 15:
5150 divided by 685 is 7 with a remainder of 355.
The number 7 becomes the next digit in our result. 
Result so far: 133266.9824817
If we subtract 4795 from 5150, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Step 16:
When dividing 3550 by 685, we get 5 with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 133266.98248175
Subtracting 3425 from 3550 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

In conclusion, the division gives 133266.98248175 with a balance of 1.25e-07.
