90085984 ÷ 685 
We want to divide 90085984 by 685.

Going ahead to step 1:
When dividing 9 by 685, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 685

On to step 2:
When dividing 90 by 685, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Bring next digit (0) of the dividend behind the 90 and repeat the process: 900 / 685

On to step 3:
The number 685 fits into 900 1 times, leaving a remainder of 215.
The next digit of our result is 1. 
Result so far: 1.0
If we take 685 away from 900, we end up with 215.
Bring next digit (8) of the dividend behind the 215 and repeat the process: 2158 / 685

Let's proceed to step 4:
685 can be fit into 2158 3 times, resulting in a remainder of 103.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 2055 away from 2158, we end up with 103.
Grab the next digit (5) from the dividend, add it to 103, then carry on: 1035 / 685

Going ahead to step 5:
If we divide 1035 by 685, we get 1 and a remainder of 350.
The next digit of our result is 1. 
Result so far: 131.0
Subtract 685 from 1035 to get 350.
Bring next digit (9) of the dividend behind the 350 and repeat the process: 3509 / 685

On to step 6:
685 can be fit into 3509 5 times, resulting in a remainder of 84.
The number 5 becomes the next digit in our result. 
Result so far: 1315.0
Deduct 3425 from 3509 and we're left with 84.
Bring next digit (8) of the dividend behind the 84 and repeat the process: 848 / 685

On to step 7:
848 divided by 685 is 1 with a remainder of 163.
The number 1 becomes the next digit in our result. 
Result so far: 13151.0
Deduct 685 from 848 and we're left with 163.
Take the next digit (4) from the dividend and append it to 163, then repeat: 1634 / 685

On to step 8:
When dividing 1634 by 685, we get 2 with a remainder of 264.
The next digit of our result is 2. 
Result so far: 131512.0
If we subtract 1370 from 1634, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 9:
685 can be fit into 2640 3 times, resulting in a remainder of 585.
Write down 3 as next digit of the result. 
Result so far: 131512.3
Deduct 2055 from 2640 and we're left with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Going ahead to step 10:
685 goes into 5850 8 times with a remainder of 370.
Use 8 as the next digit of our solution. 
Result so far: 131512.38
If we subtract 5480 from 5850, we 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.

Step 11:
685 can be fit into 3700 5 times, resulting in a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 131512.385
If we subtract 3425 from 3700, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 12:
When dividing 2750 by 685, we get 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 131512.3854
Subtracting 2740 from 2750 leaves us 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.

Advancing to step 13:
The number 685 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 131512.3854
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 14:
When dividing 1000 by 685, we get 1 with a remainder of 315.
The number 1 becomes the next digit in our result. 
Result so far: 131512.385401
Subtract 685 from 1000 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Step 15:
The number 685 fits into 3150 4 times, leaving a remainder of 410.
Put 4 as the next digit of the answer. 
Result so far: 131512.3854014
The remainder is 410 after subtracting 2740 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 16:
685 goes into 4100 5 times with a remainder of 675.
Record the quotient 5 as the next digit in the result. 
Result so far: 131512.38540145
Subtract 3425 from 4100 to get 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

After the division, we end up with 131512.38540145 and a remainder of 6.75e-07.
