We look at the division of 10402756 by 856 
Our goal is to divide 10402756 by 856.

Going ahead to step 1:
1 divided by 856 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 856

On to step 2:
When dividing 10 by 856, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 856

Step 3:
If we divide 104 by 856, we get 0 and a remainder of 104.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 104 to get 104.
Take the next digit (0) from the dividend and append it to 104, then repeat: 1040 / 856

On to step 4:
856 goes into 1040 1 times with a remainder of 184.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 856 from 1040 and we're left with 184.
Append the next digit (2) from the dividend to 184 and continue with: 1842 / 856

Let's proceed to step 5:
856 can be fit into 1842 2 times, resulting in a remainder of 130.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 1712 from 1842, we get 130.
Include the next digit (7) from the dividend after 130, then repeat: 1307 / 856

Let's proceed to step 6:
1307 divided by 856 is 1 with a remainder of 451.
Use 1 as the next digit of our solution. 
Result so far: 121.0
If we take 856 away from 1307, we end up with 451.
Append the next digit (5) from the dividend to 451 and continue with: 4515 / 856

Moving on to step 7:
856 goes into 4515 5 times with a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 1215.0
Subtracting 4280 from 4515 leaves us with 235.
Include the next digit (6) from the dividend after 235, then repeat: 2356 / 856

On to step 8:
When dividing 2356 by 856, we get 2 with a remainder of 644.
Record the quotient 2 as the next digit in the result. 
Result so far: 12152.0
If we subtract 1712 from 2356, we get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

On to step 9:
856 goes into 6440 7 times with a remainder of 448.
Use 7 as the next digit of our solution. 
Result so far: 12152.7
Subtract 5992 from 6440 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Let's proceed to step 10:
4480 divided by 856 is 5 with a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 12152.75
Deduct 4280 from 4480 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 11:
When dividing 2000 by 856, we get 2 with a remainder of 288.
Put 2 as the next digit of the answer. 
Result so far: 12152.752
Subtracting 1712 from 2000 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 12:
2880 divided by 856 is 3 with a remainder of 312.
Write down 3 as next digit of the result. 
Result so far: 12152.7523
If we take 2568 away from 2880, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 13:
856 goes into 3120 3 times with a remainder of 552.
Use 3 as the next digit of our solution. 
Result so far: 12152.75233
Deduct 2568 from 3120 and we're left with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

The final result is 12152.75233 with a remainder of 0.000552.
