We look at the division of 66331615 by 819 
We want to figure out the number of times 66331615 can be divided by 819.

Going ahead to step 1:
819 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 819

Advancing to step 2:
If we divide 66 by 819, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Bring next digit (3) of the dividend behind the 66 and repeat the process: 663 / 819

Let's proceed to step 3:
663 divided by 819 is 0 with a remainder of 663.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 663, we end up with 663.
Take the next digit (3) from the dividend and append it to 663, then repeat: 6633 / 819

Step 4:
The number 819 fits into 6633 8 times, leaving a remainder of 81.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 6552 from 6633, we get 81.
Take the next digit (1) from the dividend and append it to 81, then repeat: 811 / 819

Moving on to step 5:
811 divided by 819 is 0 with a remainder of 811.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
If we take 0 away from 811, we end up with 811.
Append the next digit (6) from the dividend to 811 and continue with: 8116 / 819

Going ahead to step 6:
If we divide 8116 by 819, we get 9 and a remainder of 745.
Record the quotient 9 as the next digit in the result. 
Result so far: 809.0
Subtract 7371 from 8116 to get 745.
Append the next digit (1) from the dividend to 745 and continue with: 7451 / 819

Advancing to step 7:
819 can be fit into 7451 9 times, resulting in a remainder of 80.
Use 9 as the next digit of our solution. 
Result so far: 8099.0
Deduct 7371 from 7451 and we're left with 80.
Append the next digit (5) from the dividend to 80 and continue with: 805 / 819

Going ahead to step 8:
819 can be fit into 805 0 times, resulting in a remainder of 805.
Write down 0 as next digit of the result. 
Result so far: 80990.0
Subtracting 0 from 805 leaves us with 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

Advancing to step 9:
If we divide 8050 by 819, we get 9 and a remainder of 679.
The number 9 becomes the next digit in our result. 
Result so far: 80990.9
If we take 7371 away from 8050, we end up with 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Going ahead to step 10:
If we divide 6790 by 819, we get 8 and a remainder of 238.
The number 8 becomes the next digit in our result. 
Result so far: 80990.98
The remainder is 238 after subtracting 6552 from 6790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 11:
If we divide 2380 by 819, we get 2 and a remainder of 742.
Put 2 as the next digit of the answer. 
Result so far: 80990.982
If we take 1638 away from 2380, we end up with 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Step 12:
819 can be fit into 7420 9 times, resulting in a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 80990.9829
Subtracting 7371 from 7420 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 13:
819 goes into 490 0 times with a remainder of 490.
The number 0 becomes the next digit in our result. 
Result so far: 80990.9829
If we take 0 away from 490, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 14:
If we divide 4900 by 819, we get 5 and a remainder of 805.
Put 5 as the next digit of the answer. 
Result so far: 80990.982905
If we take 4095 away from 4900, we end up with 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

Let's proceed to step 15:
If we divide 8050 by 819, we get 9 and a remainder of 679.
Use 9 as the next digit of our solution. 
Result so far: 80990.9829059
Subtract 7371 from 8050 to get 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Let's proceed to step 16:
819 can be fit into 6790 8 times, resulting in a remainder of 238.
The number 8 becomes the next digit in our result. 
Result so far: 80990.98290598
Deduct 6552 from 6790 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

After the division, we end up with 80990.98290598 and a remainder of 2.38e-07.
