66903219 ÷ 826 
We want to figure out the number of times 66903219 can be divided by 826.

Let's proceed to step 1:
If we divide 6 by 826, we get 0 and 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 / 826

Let's proceed to step 2:
826 goes into 66 0 times with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Append the next digit (9) from the dividend to 66 and continue with: 669 / 826

Moving on to step 3:
When dividing 669 by 826, we get 0 with a remainder of 669.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 669, we get 669.
Append the next digit (0) from the dividend to 669 and continue with: 6690 / 826

On to step 4:
826 can be fit into 6690 8 times, resulting in a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 6608 from 6690 and we're left with 82.
Grab the next digit (3) from the dividend, add it to 82, then carry on: 823 / 826

Step 5:
When dividing 823 by 826, we get 0 with a remainder of 823.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
If we take 0 away from 823, we end up with 823.
Append the next digit (2) from the dividend to 823 and continue with: 8232 / 826

Moving on to step 6:
When dividing 8232 by 826, we get 9 with a remainder of 798.
Put 9 as the next digit of the answer. 
Result so far: 809.0
Subtracting 7434 from 8232 leaves us with 798.
Take the next digit (1) from the dividend and append it to 798, then repeat: 7981 / 826

Going ahead to step 7:
The number 826 fits into 7981 9 times, leaving a remainder of 547.
Record the quotient 9 as the next digit in the result. 
Result so far: 8099.0
Subtracting 7434 from 7981 leaves us with 547.
Append the next digit (9) from the dividend to 547 and continue with: 5479 / 826

Let's proceed to step 8:
If we divide 5479 by 826, we get 6 and a remainder of 523.
The number 6 becomes the next digit in our result. 
Result so far: 80996.0
Subtracting 4956 from 5479 leaves us with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Advancing to step 9:
5230 divided by 826 is 6 with a remainder of 274.
The next digit of our result is 6. 
Result so far: 80996.6
The remainder is 274 after subtracting 4956 from 5230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Moving on to step 10:
When dividing 2740 by 826, we get 3 with a remainder of 262.
Use 3 as the next digit of our solution. 
Result so far: 80996.63
Deduct 2478 from 2740 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Advancing to step 11:
826 goes into 2620 3 times with a remainder of 142.
The next digit of our result is 3. 
Result so far: 80996.633
Deduct 2478 from 2620 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Our division results in 80996.633 with a remaining 0.0142.
