1522553 ÷ 857 
We want to figure out the number of times 1522553 can be divided by 857.

On to step 1:
If we divide 1 by 857, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
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 / 857

Let's proceed to step 2:
15 divided by 857 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 857

Going ahead to step 3:
The number 857 fits into 152 0 times, leaving a remainder of 152.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 152, we end up with 152.
Grab the next digit (2) from the dividend, add it to 152, then carry on: 1522 / 857

On to step 4:
If we divide 1522 by 857, we get 1 and a remainder of 665.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 857 from 1522, we get 665.
Include the next digit (5) from the dividend after 665, then repeat: 6655 / 857

On to step 5:
857 goes into 6655 7 times with a remainder of 656.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 656 after subtracting 5999 from 6655.
Fetch the next digit (5) from the dividend, attach it to 656 and continue: 6565 / 857

On to step 6:
When dividing 6565 by 857, we get 7 with a remainder of 566.
Put 7 as the next digit of the answer. 
Result so far: 177.0
Subtract 5999 from 6565 to get 566.
Include the next digit (3) from the dividend after 566, then repeat: 5663 / 857

Step 7:
857 can be fit into 5663 6 times, resulting in a remainder of 521.
Record the quotient 6 as the next digit in the result. 
Result so far: 1776.0
Deduct 5142 from 5663 and we're left with 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

Going ahead to step 8:
If we divide 5210 by 857, we get 6 and a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 1776.6
If we subtract 5142 from 5210, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 9:
When dividing 680 by 857, we get 0 with a remainder of 680.
Put 0 as the next digit of the answer. 
Result so far: 1776.6
Subtract 0 from 680 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 10:
857 goes into 6800 7 times with a remainder of 801.
The next digit of our result is 7. 
Result so far: 1776.607
If we subtract 5999 from 6800, we get 801.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8010, and continue the process.

Step 11:
857 can be fit into 8010 9 times, resulting in a remainder of 297.
Record the quotient 9 as the next digit in the result. 
Result so far: 1776.6079
Subtracting 7713 from 8010 leaves us with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

On to step 12:
857 can be fit into 2970 3 times, resulting in a remainder of 399.
Use 3 as the next digit of our solution. 
Result so far: 1776.60793
Subtract 2571 from 2970 to get 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Step 13:
857 can be fit into 3990 4 times, resulting in a remainder of 562.
Write down 4 as next digit of the result. 
Result so far: 1776.607934
Subtract 3428 from 3990 to get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Going ahead to step 14:
When dividing 5620 by 857, we get 6 with a remainder of 478.
Write down 6 as next digit of the result. 
Result so far: 1776.6079346
Subtract 5142 from 5620 to get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

On to step 15:
When dividing 4780 by 857, we get 5 with a remainder of 495.
The number 5 becomes the next digit in our result. 
Result so far: 1776.60793465
If we subtract 4285 from 4780, we get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

The final outcome is 1776.60793465, with a leftover of 4.95e-07.
