1571020 ÷ 685 
We want to divide 1571020 by 685.

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.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 685

On to step 2:
If we divide 15 by 685, we get 0 and a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 685

Going ahead to step 3:
When dividing 157 by 685, we get 0 with a remainder of 157.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 157 to get 157.
Fetch the next digit (1) from the dividend, attach it to 157 and continue: 1571 / 685

Moving on to step 4:
685 can be fit into 1571 2 times, resulting in a remainder of 201.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1370 from 1571, we get 201.
Grab the next digit (0) from the dividend, add it to 201, then carry on: 2010 / 685

On to step 5:
685 can be fit into 2010 2 times, resulting in a remainder of 640.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 1370 from 2010, we get 640.
Bring next digit (2) of the dividend behind the 640 and repeat the process: 6402 / 685

Step 6:
If we divide 6402 by 685, we get 9 and a remainder of 237.
The next digit of our result is 9. 
Result so far: 229.0
Subtract 6165 from 6402 to get 237.
Include the next digit (0) from the dividend after 237, then repeat: 2370 / 685

Advancing to step 7:
If we divide 2370 by 685, we get 3 and a remainder of 315.
The next digit of our result is 3. 
Result so far: 2293.0
Subtract 2055 from 2370 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.

Let's proceed to step 8:
685 goes into 3150 4 times with a remainder of 410.
The next digit of our result is 4. 
Result so far: 2293.4
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 9:
685 can be fit into 4100 5 times, resulting in a remainder of 675.
Use 5 as the next digit of our solution. 
Result so far: 2293.45
The remainder is 675 after subtracting 3425 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Going ahead to step 10:
When dividing 6750 by 685, we get 9 with a remainder of 585.
Write down 9 as next digit of the result. 
Result so far: 2293.459
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.

Step 11:
When dividing 5850 by 685, we get 8 with a remainder of 370.
The number 8 becomes the next digit in our result. 
Result so far: 2293.4598
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.

On to step 12:
685 can be fit into 3700 5 times, resulting in a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 2293.45985
Subtracting 3425 from 3700 leaves us with 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 13:
685 can be fit into 2750 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 2293.459854
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.

Step 14:
The number 685 fits into 100 0 times, leaving a remainder of 100.
The next digit of our result is 0. 
Result so far: 2293.459854
If we take 0 away from 100, we end up with 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 15:
1000 divided by 685 is 1 with a remainder of 315.
Put 1 as the next digit of the answer. 
Result so far: 2293.45985401
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.

The quotient of the division is 2293.45985401, and the remainder is 3.15e-07.
