1312415 ÷ 857 
We want to figure out the number of times 1312415 can be divided by 857.

Going ahead to step 1:
When dividing 1 by 857, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 857

Advancing to step 2:
If we divide 13 by 857, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 857

Going ahead to step 3:
When dividing 131 by 857, we get 0 with a remainder of 131.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 131 after subtracting 0 from 131.
Bring next digit (2) of the dividend behind the 131 and repeat the process: 1312 / 857

Moving on to step 4:
If we divide 1312 by 857, we get 1 and a remainder of 455.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 455 after subtracting 857 from 1312.
Append the next digit (4) from the dividend to 455 and continue with: 4554 / 857

On to step 5:
The number 857 fits into 4554 5 times, leaving a remainder of 269.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 4285 from 4554 to get 269.
Include the next digit (1) from the dividend after 269, then repeat: 2691 / 857

Advancing to step 6:
The number 857 fits into 2691 3 times, leaving a remainder of 120.
Use 3 as the next digit of our solution. 
Result so far: 153.0
The remainder is 120 after subtracting 2571 from 2691.
Append the next digit (5) from the dividend to 120 and continue with: 1205 / 857

Step 7:
857 goes into 1205 1 times with a remainder of 348.
Use 1 as the next digit of our solution. 
Result so far: 1531.0
Deduct 857 from 1205 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 8:
3480 divided by 857 is 4 with a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 1531.4
Subtracting 3428 from 3480 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 9:
857 goes into 520 0 times with a remainder of 520.
Put 0 as the next digit of the answer. 
Result so far: 1531.4
If we subtract 0 from 520, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 10:
The number 857 fits into 5200 6 times, leaving a remainder of 58.
The number 6 becomes the next digit in our result. 
Result so far: 1531.406
Subtracting 5142 from 5200 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 11:
When dividing 580 by 857, we get 0 with a remainder of 580.
The number 0 becomes the next digit in our result. 
Result so far: 1531.406
Subtracting 0 from 580 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 12:
The number 857 fits into 5800 6 times, leaving a remainder of 658.
The number 6 becomes the next digit in our result. 
Result so far: 1531.40606
If we subtract 5142 from 5800, we get 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Going ahead to step 13:
6580 divided by 857 is 7 with a remainder of 581.
Write down 7 as next digit of the result. 
Result so far: 1531.406067
The remainder is 581 after subtracting 5999 from 6580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Moving on to step 14:
857 can be fit into 5810 6 times, resulting in a remainder of 668.
Record the quotient 6 as the next digit in the result. 
Result so far: 1531.4060676
Deduct 5142 from 5810 and we're left with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Let's proceed to step 15:
If we divide 6680 by 857, we get 7 and a remainder of 681.
The next digit of our result is 7. 
Result so far: 1531.40606767
If we subtract 5999 from 6680, we get 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

The final result is 1531.40606767 with a remainder of 6.81e-07.
