We look at the division of 66329786 by 802 
The aim is to understand the frequency of 802 in 66329786.

Advancing to step 1:
The number 802 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 802

Let's proceed to step 2:
The number 802 fits into 66 0 times, leaving 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 / 802

Step 3:
If we divide 663 by 802, we get 0 and a remainder of 663.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 663 leaves us with 663.
Append the next digit (2) from the dividend to 663 and continue with: 6632 / 802

Let's proceed to step 4:
802 can be fit into 6632 8 times, resulting in a remainder of 216.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 6416 from 6632 and we're left with 216.
Fetch the next digit (9) from the dividend, attach it to 216 and continue: 2169 / 802

Advancing to step 5:
2169 divided by 802 is 2 with a remainder of 565.
Use 2 as the next digit of our solution. 
Result so far: 82.0
Deduct 1604 from 2169 and we're left with 565.
Take the next digit (7) from the dividend and append it to 565, then repeat: 5657 / 802

Advancing to step 6:
5657 divided by 802 is 7 with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 827.0
Subtract 5614 from 5657 to get 43.
Include the next digit (8) from the dividend after 43, then repeat: 438 / 802

On to step 7:
802 goes into 438 0 times with a remainder of 438.
Use 0 as the next digit of our solution. 
Result so far: 8270.0
Subtracting 0 from 438 leaves us with 438.
Append the next digit (6) from the dividend to 438 and continue with: 4386 / 802

Moving on to step 8:
802 can be fit into 4386 5 times, resulting in a remainder of 376.
The number 5 becomes the next digit in our result. 
Result so far: 82705.0
The remainder is 376 after subtracting 4010 from 4386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 9:
If we divide 3760 by 802, we get 4 and a remainder of 552.
Write down 4 as next digit of the result. 
Result so far: 82705.4
Subtracting 3208 from 3760 leaves us with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Step 10:
When dividing 5520 by 802, we get 6 with a remainder of 708.
Record the quotient 6 as the next digit in the result. 
Result so far: 82705.46
If we take 4812 away from 5520, we end up with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Moving on to step 11:
7080 divided by 802 is 8 with a remainder of 664.
Write down 8 as next digit of the result. 
Result so far: 82705.468
Deduct 6416 from 7080 and we're left with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Advancing to step 12:
When dividing 6640 by 802, we get 8 with a remainder of 224.
Use 8 as the next digit of our solution. 
Result so far: 82705.4688
The remainder is 224 after subtracting 6416 from 6640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The quotient of the division is 82705.4688, and the remainder is 0.00224.
