We're dividing 99985150 by 685 
Let's see how many times 685 fits into 99985150.

Advancing to step 1:
685 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 685

Let's proceed to step 2:
685 can be fit into 99 0 times, resulting in a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Grab the next digit (9) from the dividend, add it to 99, then carry on: 999 / 685

Going ahead to step 3:
685 goes into 999 1 times with a remainder of 314.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 685 from 999 to get 314.
Take the next digit (8) from the dividend and append it to 314, then repeat: 3148 / 685

Going ahead to step 4:
If we divide 3148 by 685, we get 4 and a remainder of 408.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 2740 away from 3148, we end up with 408.
Bring next digit (5) of the dividend behind the 408 and repeat the process: 4085 / 685

Moving on to step 5:
685 goes into 4085 5 times with a remainder of 660.
Put 5 as the next digit of the answer. 
Result so far: 145.0
If we subtract 3425 from 4085, we get 660.
Append the next digit (1) from the dividend to 660 and continue with: 6601 / 685

Step 6:
The number 685 fits into 6601 9 times, leaving a remainder of 436.
Record the quotient 9 as the next digit in the result. 
Result so far: 1459.0
Deduct 6165 from 6601 and we're left with 436.
Fetch the next digit (5) from the dividend, attach it to 436 and continue: 4365 / 685

Step 7:
685 can be fit into 4365 6 times, resulting in a remainder of 255.
Record the quotient 6 as the next digit in the result. 
Result so far: 14596.0
The remainder is 255 after subtracting 4110 from 4365.
Append the next digit (0) from the dividend to 255 and continue with: 2550 / 685

Let's proceed to step 8:
The number 685 fits into 2550 3 times, leaving a remainder of 495.
Use 3 as the next digit of our solution. 
Result so far: 145963.0
If we subtract 2055 from 2550, we get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Moving on to step 9:
When dividing 4950 by 685, we get 7 with a remainder of 155.
Use 7 as the next digit of our solution. 
Result so far: 145963.7
The remainder is 155 after subtracting 4795 from 4950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 10:
685 can be fit into 1550 2 times, resulting in a remainder of 180.
Write down 2 as next digit of the result. 
Result so far: 145963.72
Deduct 1370 from 1550 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 11:
685 can be fit into 1800 2 times, resulting in a remainder of 430.
Use 2 as the next digit of our solution. 
Result so far: 145963.722
If we subtract 1370 from 1800, we get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

In conclusion, the division gives 145963.722 with a balance of 0.043.
