98405689 ÷ 685 
Let's see how many times 685 fits into 98405689.

Moving on to step 1:
685 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 685

Advancing to step 2:
The number 685 fits into 98 0 times, leaving a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Append the next digit (4) from the dividend to 98 and continue with: 984 / 685

Going ahead to step 3:
685 can be fit into 984 1 times, resulting in a remainder of 299.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 685 from 984 and we're left with 299.
Bring next digit (0) of the dividend behind the 299 and repeat the process: 2990 / 685

Step 4:
The number 685 fits into 2990 4 times, leaving a remainder of 250.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 2740 from 2990 and we're left with 250.
Bring next digit (5) of the dividend behind the 250 and repeat the process: 2505 / 685

On to step 5:
When dividing 2505 by 685, we get 3 with a remainder of 450.
The next digit of our result is 3. 
Result so far: 143.0
The remainder is 450 after subtracting 2055 from 2505.
Fetch the next digit (6) from the dividend, attach it to 450 and continue: 4506 / 685

Going ahead to step 6:
When dividing 4506 by 685, we get 6 with a remainder of 396.
The next digit of our result is 6. 
Result so far: 1436.0
Subtracting 4110 from 4506 leaves us with 396.
Take the next digit (8) from the dividend and append it to 396, then repeat: 3968 / 685

On to step 7:
When dividing 3968 by 685, we get 5 with a remainder of 543.
The next digit of our result is 5. 
Result so far: 14365.0
Deduct 3425 from 3968 and we're left with 543.
Append the next digit (9) from the dividend to 543 and continue with: 5439 / 685

Moving on to step 8:
5439 divided by 685 is 7 with a remainder of 644.
Use 7 as the next digit of our solution. 
Result so far: 143657.0
Subtracting 4795 from 5439 leaves us with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Step 9:
685 can be fit into 6440 9 times, resulting in a remainder of 275.
Use 9 as the next digit of our solution. 
Result so far: 143657.9
The remainder is 275 after subtracting 6165 from 6440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 10:
If we divide 2750 by 685, we get 4 and a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 143657.94
Deduct 2740 from 2750 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
685 goes into 100 0 times with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 143657.94
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 12:
1000 divided by 685 is 1 with a remainder of 315.
The next digit of our result is 1. 
Result so far: 143657.9401
The remainder is 315 after subtracting 685 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 13:
The number 685 fits into 3150 4 times, leaving a remainder of 410.
The number 4 becomes the next digit in our result. 
Result so far: 143657.94014
If we subtract 2740 from 3150, we get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 14:
685 goes into 4100 5 times with a remainder of 675.
Put 5 as the next digit of the answer. 
Result so far: 143657.940145
If we take 3425 away from 4100, we end up with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Step 15:
685 can be fit into 6750 9 times, resulting in a remainder of 585.
The number 9 becomes the next digit in our result. 
Result so far: 143657.9401459
If we subtract 6165 from 6750, we get 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Let's proceed to step 16:
5850 divided by 685 is 8 with a remainder of 370.
Write down 8 as next digit of the result. 
Result so far: 143657.94014598
Subtract 5480 from 5850 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

In conclusion, the division gives 143657.94014598 with a balance of 3.7e-07.
