We want to divide 64539099 by 849.

Going ahead to step 1:
6 divided by 849 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 849

On to step 2:
849 can be fit into 64 0 times, resulting in a remainder of 64.
Use 0 as the next digit of our solution.

The remainder is 64 after subtracting 0 from 64.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 849

Moving on to step 3:
When dividing 645 by 849, we get 0 with a remainder of 645.
Write down 0 as next digit of the result.

Moving on to step 5:
5109 divided by 849 is 6 with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Subtract 5094 from 5109 to get 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 849

On to step 6:
849 goes into 150 0 times with a remainder of 150.
The next digit of our result is 0. 
Result so far: 760.0
Deduct 0 from 150 and we're left with 150.

Let's proceed to step 7:
849 goes into 1509 1 times with a remainder of 660.
Put 1 as the next digit of the answer. 
Result so far: 7601.0
The remainder is 660 after subtracting 849 from 1509.
Include the next digit (9) from the dividend after 660, then repeat: 6609 / 849

Let's proceed to step 8:
6609 divided by 849 is 7 with a remainder of 666.
Use 7 as the next digit of our solution. 
Result so far: 76017.0
If we take 5943 away from 6609, we end up with 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Let's proceed to step 9:
849 goes into 6660 7 times with a remainder of 717.
The next digit of our result is 7. 
Result so far: 76017.7
Subtract 5943 from 6660 to get 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

Going ahead to step 10:
The number 849 fits into 7170 8 times, leaving a remainder of 378.
The number 8 becomes the next digit in our result. 
Result so far: 76017.78
Subtracting 6792 from 7170 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Step 11:
849 can be fit into 3780 4 times, resulting in a remainder of 384.
Write down 4 as next digit of the result. 
Result so far: 76017.784
The remainder is 384 after subtracting 3396 from 3780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 12:
849 goes into 3840 4 times with a remainder of 444.
The number 4 becomes the next digit in our result. 
Result so far: 76017.7844
Deduct 3396 from 3840 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Our division results in 76017.7844 with a remaining 0.00444.
