698853 ÷ 66 
The aim is to understand the frequency of 66 in 698853.

Step 1:
66 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
Subtracting 0 from 6 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 66

Let's proceed to step 2:
The number 66 fits into 69 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 66 away from 69, we end up with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 66

Step 3:
When dividing 38 by 66, we get 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 38 after subtracting 0 from 38.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 66

Advancing to step 4:
388 divided by 66 is 5 with a remainder of 58.
Write down 5 as next digit of the result. 
Result so far: 105.0
Deduct 330 from 388 and we're left with 58.
Take the next digit (5) from the dividend and append it to 58, then repeat: 585 / 66

Advancing to step 5:
66 can be fit into 585 8 times, resulting in a remainder of 57.
Record the quotient 8 as the next digit in the result. 
Result so far: 1058.0
If we take 528 away from 585, we end up with 57.
Grab the next digit (3) from the dividend, add it to 57, then carry on: 573 / 66

On to step 6:
66 can be fit into 573 8 times, resulting in a remainder of 45.
Write down 8 as next digit of the result. 
Result so far: 10588.0
Deduct 528 from 573 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 7:
450 divided by 66 is 6 with a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 10588.6
Deduct 396 from 450 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 8:
540 divided by 66 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 10588.68
If we subtract 528 from 540, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
If we divide 120 by 66, we get 1 and a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 10588.681
If we take 66 away from 120, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 10:
66 goes into 540 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 10588.6818
Subtract 528 from 540 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
If we divide 120 by 66, we get 1 and a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 10588.68181
Subtracting 66 from 120 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
If we divide 540 by 66, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 10588.681818
Subtract 528 from 540 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
120 divided by 66 is 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 10588.6818181
Subtract 66 from 120 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 14:
The number 66 fits into 540 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 10588.68181818
The remainder is 12 after subtracting 528 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 10588.68181818 with a balance of 1.2e-08.
