We divide 12642023 by 685
We want to divide 12642023 by 685.

Moving on to step 1:
If we divide 1 by 685, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 685

Going ahead to step 2:
The number 685 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 685

Step 3:
If we divide 126 by 685, we get 0 and a remainder of 126.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 126, we get 126.
Bring next digit (4) of the dividend behind the 126 and repeat the process: 1264 / 685

Step 4:
685 can be fit into 1264 1 times, resulting in a remainder of 579.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 685 from 1264 and we're left with 579.
Bring next digit (2) of the dividend behind the 579 and repeat the process: 5792 / 685

On to step 5:
When dividing 5792 by 685, we get 8 with a remainder of 312.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 312 after subtracting 5480 from 5792.
Append the next digit (0) from the dividend to 312 and continue with: 3120 / 685

Advancing to step 6:
The number 685 fits into 3120 4 times, leaving a remainder of 380.
The number 4 becomes the next digit in our result. 
Result so far: 184.0
Subtracting 2740 from 3120 leaves us with 380.
Take the next digit (2) from the dividend and append it to 380, then repeat: 3802 / 685

Going ahead to step 7:
685 can be fit into 3802 5 times, resulting in a remainder of 377.
Use 5 as the next digit of our solution. 
Result so far: 1845.0
Deduct 3425 from 3802 and we're left with 377.
Grab the next digit (3) from the dividend, add it to 377, then carry on: 3773 / 685

Step 8:
When dividing 3773 by 685, we get 5 with a remainder of 348.
The number 5 becomes the next digit in our result. 
Result so far: 18455.0
If we subtract 3425 from 3773, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 9:
685 can be fit into 3480 5 times, resulting in a remainder of 55.
The next digit of our result is 5. 
Result so far: 18455.5
Subtract 3425 from 3480 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 10:
If we divide 550 by 685, we get 0 and a remainder of 550.
The number 0 becomes the next digit in our result. 
Result so far: 18455.5
Deduct 0 from 550 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 11:
When dividing 5500 by 685, we get 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 18455.508
The remainder is 20 after subtracting 5480 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
200 divided by 685 is 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 18455.508
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 13:
685 can be fit into 2000 2 times, resulting in a remainder of 630.
The next digit of our result is 2. 
Result so far: 18455.50802
If we subtract 1370 from 2000, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Let's proceed to step 14:
If we divide 6300 by 685, we get 9 and a remainder of 135.
Write down 9 as next digit of the result. 
Result so far: 18455.508029
Subtract 6165 from 6300 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 15:
685 can be fit into 1350 1 times, resulting in a remainder of 665.
Write down 1 as next digit of the result. 
Result so far: 18455.5080291
Subtract 685 from 1350 to get 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Step 16:
When dividing 6650 by 685, we get 9 with a remainder of 485.
Write down 9 as next digit of the result. 
Result so far: 18455.50802919
If we take 6165 away from 6650, we end up with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

The final outcome is 18455.50802919, with a leftover of 4.85e-07.
