We're dividing 64653661 by 819 
We want to divide 64653661 by 819.

On to step 1:
819 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 819

Going ahead to step 2:
The number 819 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Fetch the next digit (6) from the dividend, attach it to 64 and continue: 646 / 819

Let's proceed to step 3:
If we divide 646 by 819, we get 0 and a remainder of 646.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 646, we end up with 646.
Fetch the next digit (5) from the dividend, attach it to 646 and continue: 6465 / 819

Moving on to step 4:
6465 divided by 819 is 7 with a remainder of 732.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 5733 from 6465 and we're left with 732.
Bring next digit (3) of the dividend behind the 732 and repeat the process: 7323 / 819

Moving on to step 5:
7323 divided by 819 is 8 with a remainder of 771.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
If we take 6552 away from 7323, we end up with 771.
Include the next digit (6) from the dividend after 771, then repeat: 7716 / 819

Step 6:
7716 divided by 819 is 9 with a remainder of 345.
Put 9 as the next digit of the answer. 
Result so far: 789.0
If we take 7371 away from 7716, we end up with 345.
Include the next digit (6) from the dividend after 345, then repeat: 3456 / 819

Advancing to step 7:
The number 819 fits into 3456 4 times, leaving a remainder of 180.
The next digit of our result is 4. 
Result so far: 7894.0
If we subtract 3276 from 3456, we get 180.
Grab the next digit (1) from the dividend, add it to 180, then carry on: 1801 / 819

Step 8:
When dividing 1801 by 819, we get 2 with a remainder of 163.
Record the quotient 2 as the next digit in the result. 
Result so far: 78942.0
Subtracting 1638 from 1801 leaves us with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Let's proceed to step 9:
The number 819 fits into 1630 1 times, leaving a remainder of 811.
Use 1 as the next digit of our solution. 
Result so far: 78942.1
The remainder is 811 after subtracting 819 from 1630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8110, and continue the process.

Moving on to step 10:
819 can be fit into 8110 9 times, resulting in a remainder of 739.
Record the quotient 9 as the next digit in the result. 
Result so far: 78942.19
The remainder is 739 after subtracting 7371 from 8110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

Let's proceed to step 11:
7390 divided by 819 is 9 with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 78942.199
Deduct 7371 from 7390 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final result is 78942.199 with a remainder of 0.0019.
