We look at the division of 90243844 by 685 
Our goal is to divide 90243844 by 685.

Moving on to step 1:
9 divided by 685 is 0 with a remainder of 9.
The number 0 becomes the next digit in our 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:
If we divide 90 by 685, we get 0 and a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Fetch the next digit (2) from the dividend, attach it to 90 and continue: 902 / 685

Going ahead to step 3:
If we divide 902 by 685, we get 1 and a remainder of 217.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 217 after subtracting 685 from 902.
Include the next digit (4) from the dividend after 217, then repeat: 2174 / 685

Step 4:
The number 685 fits into 2174 3 times, leaving a remainder of 119.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 2055 from 2174 and we're left with 119.
Include the next digit (3) from the dividend after 119, then repeat: 1193 / 685

On to step 5:
When dividing 1193 by 685, we get 1 with a remainder of 508.
The next digit of our result is 1. 
Result so far: 131.0
If we subtract 685 from 1193, we get 508.
Append the next digit (8) from the dividend to 508 and continue with: 5088 / 685

On to step 6:
5088 divided by 685 is 7 with a remainder of 293.
Write down 7 as next digit of the result. 
Result so far: 1317.0
Deduct 4795 from 5088 and we're left with 293.
Fetch the next digit (4) from the dividend, attach it to 293 and continue: 2934 / 685

Advancing to step 7:
2934 divided by 685 is 4 with a remainder of 194.
The number 4 becomes the next digit in our result. 
Result so far: 13174.0
If we take 2740 away from 2934, we end up with 194.
Bring next digit (4) of the dividend behind the 194 and repeat the process: 1944 / 685

Moving on to step 8:
1944 divided by 685 is 2 with a remainder of 574.
The number 2 becomes the next digit in our result. 
Result so far: 131742.0
If we subtract 1370 from 1944, we get 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Moving on to step 9:
If we divide 5740 by 685, we get 8 and a remainder of 260.
The number 8 becomes the next digit in our result. 
Result so far: 131742.8
If we subtract 5480 from 5740, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 10:
685 can be fit into 2600 3 times, resulting in a remainder of 545.
Write down 3 as next digit of the result. 
Result so far: 131742.83
Subtract 2055 from 2600 to get 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

On to step 11:
685 can be fit into 5450 7 times, resulting in a remainder of 655.
Record the quotient 7 as the next digit in the result. 
Result so far: 131742.837
If we subtract 4795 from 5450, we get 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Step 12:
685 can be fit into 6550 9 times, resulting in a remainder of 385.
Record the quotient 9 as the next digit in the result. 
Result so far: 131742.8379
Deduct 6165 from 6550 and we're left with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Going ahead to step 13:
685 can be fit into 3850 5 times, resulting in a remainder of 425.
Write down 5 as next digit of the result. 
Result so far: 131742.83795
If we subtract 3425 from 3850, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Moving on to step 14:
When dividing 4250 by 685, we get 6 with a remainder of 140.
Use 6 as the next digit of our solution. 
Result so far: 131742.837956
The remainder is 140 after subtracting 4110 from 4250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 15:
If we divide 1400 by 685, we get 2 and a remainder of 30.
The next digit of our result is 2. 
Result so far: 131742.8379562
Subtract 1370 from 1400 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 16:
When dividing 300 by 685, we get 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 131742.8379562
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final result is 131742.8379562 with a remainder of 3e-07.
