1549664 divided by 851 
Let's see how many times 851 fits into 1549664.

Advancing to step 1:
When dividing 1 by 851, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 851

Moving on to step 2:
The number 851 fits into 15 0 times, leaving a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 851

On to step 3:
851 goes into 154 0 times with a remainder of 154.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 154 to get 154.
Fetch the next digit (9) from the dividend, attach it to 154 and continue: 1549 / 851

Let's proceed to step 4:
851 goes into 1549 1 times with a remainder of 698.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 851 from 1549 leaves us with 698.
Fetch the next digit (6) from the dividend, attach it to 698 and continue: 6986 / 851

Step 5:
6986 divided by 851 is 8 with a remainder of 178.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 178 after subtracting 6808 from 6986.
Bring next digit (6) of the dividend behind the 178 and repeat the process: 1786 / 851

Moving on to step 6:
When dividing 1786 by 851, we get 2 with a remainder of 84.
Use 2 as the next digit of our solution. 
Result so far: 182.0
If we take 1702 away from 1786, we end up with 84.
Grab the next digit (4) from the dividend, add it to 84, then carry on: 844 / 851

Let's proceed to step 7:
851 can be fit into 844 0 times, resulting in a remainder of 844.
Record the quotient 0 as the next digit in the result. 
Result so far: 1820.0
If we subtract 0 from 844, we get 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

Advancing to step 8:
The number 851 fits into 8440 9 times, leaving a remainder of 781.
Record the quotient 9 as the next digit in the result. 
Result so far: 1820.9
The remainder is 781 after subtracting 7659 from 8440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7810, and continue the process.

Going ahead to step 9:
The number 851 fits into 7810 9 times, leaving a remainder of 151.
The next digit of our result is 9. 
Result so far: 1820.99
Deduct 7659 from 7810 and we're left with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

The final result is 1820.99 with a remainder of 0.151.
