When dividing 1 by 857, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 857

Let's proceed to step 2:
If we divide 16 by 857, we get 0 and a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 857

Step 3:
When dividing 166 by 857, we get 0 with a remainder of 166.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 166 and we're left with 166.
Bring next digit (8) of the dividend behind the 166 and repeat the process: 1668 / 857

Moving on to step 4:
When dividing 1668 by 857, we get 1 with a remainder of 811.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 857 from 1668 and we're left with 811.
Include the next digit (3) from the dividend after 811, then repeat: 8113 / 857

Advancing to step 5:
The number 857 fits into 8113 9 times, leaving a remainder of 400.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 7713 from 8113 to get 400.
Grab the next digit (4) from the dividend, add it to 400, then carry on: 4004 / 857

Moving on to step 6:
857 can be fit into 4004 4 times, resulting in a remainder of 576.
Write down 4 as next digit of the result. 
Result so far: 194.0
If we subtract 3428 from 4004, we get 576.
Include the next digit (0) from the dividend after 576, then repeat: 5760 / 857

Let's proceed to step 7:
The number 857 fits into 5760 6 times, leaving a remainder of 618.
Record the quotient 6 as the next digit in the result. 
Result so far: 1946.0
Subtract 5142 from 5760 to get 618.
Grab the next digit (9) from the dividend, add it to 618, then carry on: 6189 / 857

Step 8:
6189 divided by 857 is 7 with a remainder of 190.
Write down 7 as next digit of the result. 
Result so far: 19467.0
If we subtract 5999 from 6189, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 9:
If we divide 1900 by 857, we get 2 and a remainder of 186.
The number 2 becomes the next digit in our result. 
Result so far: 19467.2
Deduct 1714 from 1900 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 10:
When dividing 1860 by 857, we get 2 with a remainder of 146.
Use 2 as the next digit of our solution. 
Result so far: 19467.22
Subtract 1714 from 1860 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Our division results in 19467.22 with a remaining 0.146.
