We look at the division of 6538772 by 856 
Let's see how many times 856 fits into 6538772.

Going ahead to step 1:
The number 856 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 856

Going ahead to step 2:
65 divided by 856 is 0 with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Append the next digit (3) from the dividend to 65 and continue with: 653 / 856

Moving on to step 3:
653 divided by 856 is 0 with a remainder of 653.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 653 leaves us with 653.
Take the next digit (8) from the dividend and append it to 653, then repeat: 6538 / 856

Moving on to step 4:
When dividing 6538 by 856, we get 7 with a remainder of 546.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 5992 from 6538 leaves us with 546.
Grab the next digit (7) from the dividend, add it to 546, then carry on: 5467 / 856

On to step 5:
When dividing 5467 by 856, we get 6 with a remainder of 331.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Subtract 5136 from 5467 to get 331.
Append the next digit (7) from the dividend to 331 and continue with: 3317 / 856

Moving on to step 6:
856 goes into 3317 3 times with a remainder of 749.
Use 3 as the next digit of our solution. 
Result so far: 763.0
If we take 2568 away from 3317, we end up with 749.
Fetch the next digit (2) from the dividend, attach it to 749 and continue: 7492 / 856

Advancing to step 7:
856 goes into 7492 8 times with a remainder of 644.
Write down 8 as next digit of the result. 
Result so far: 7638.0
Deduct 6848 from 7492 and we're left with 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 8:
The number 856 fits into 6440 7 times, leaving a remainder of 448.
Record the quotient 7 as the next digit in the result. 
Result so far: 7638.7
The remainder is 448 after subtracting 5992 from 6440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 9:
856 can be fit into 4480 5 times, resulting in a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 7638.75
The remainder is 200 after subtracting 4280 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 10:
If we divide 2000 by 856, we get 2 and a remainder of 288.
Put 2 as the next digit of the answer. 
Result so far: 7638.752
Deduct 1712 from 2000 and we're left 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.

On to step 11:
If we divide 2880 by 856, we get 3 and a remainder of 312.
Use 3 as the next digit of our solution. 
Result so far: 7638.7523
Subtract 2568 from 2880 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 12:
856 can be fit into 3120 3 times, resulting in a remainder of 552.
The number 3 becomes the next digit in our result. 
Result so far: 7638.75233
If we subtract 2568 from 3120, we get 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 outcome is 7638.75233, with a leftover of 0.000552.
