The number 810 fits into 5714 7 times, leaving a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 5670 from 5714 to get 44.
Grab the next digit (7) from the dividend, add it to 44, then carry on: 447 / 810

Step 5:
447 divided by 810 is 0 with a remainder of 447.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
The remainder is 447 after subtracting 0 from 447.
Include the next digit (5) from the dividend after 447, then repeat: 4475 / 810

Going ahead to step 6:
The number 810 fits into 4475 5 times, leaving a remainder of 425.
The number 5 becomes the next digit in our result. 
Result so far: 705.0
Deduct 4050 from 4475 and we're left with 425.
Append the next digit (8) from the dividend to 425 and continue with: 4258 / 810

Going ahead to step 7:
The number 810 fits into 4258 5 times, leaving a remainder of 208.
The next digit of our result is 5. 
Result so far: 7055.0
Subtracting 4050 from 4258 leaves us with 208.
Grab the next digit (8) from the dividend, add it to 208, then carry on: 2088 / 810

Going ahead to step 8:
If we divide 2088 by 810, we get 2 and a remainder of 468.
Write down 2 as next digit of the result. 
Result so far: 70552.0
The remainder is 468 after subtracting 1620 from 2088.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Moving on to step 9:
The number 810 fits into 4680 5 times, leaving a remainder of 630.
Record the quotient 5 as the next digit in the result. 
Result so far: 70552.5
If we subtract 4050 from 4680, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 10:
6300 divided by 810 is 7 with a remainder of 630.
Put 7 as the next digit of the answer. 
Result so far: 70552.57
The remainder is 630 after subtracting 5670 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 11:
When dividing 6300 by 810, we get 7 with a remainder of 630.
Put 7 as the next digit of the answer. 
Result so far: 70552.577
Subtract 5670 from 6300 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Our division results in 70552.577 with a remaining 0.063.
