596953 divided by 66 
The aim is to understand the frequency of 66 in 596953.

Let's proceed to step 1:
When dividing 5 by 66, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 66

Going ahead to step 2:
59 divided by 66 is 0 with a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 59 leaves us with 59.
Append the next digit (6) from the dividend to 59 and continue with: 596 / 66

Going ahead to step 3:
66 can be fit into 596 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 594 away from 596, we end up with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 66

Let's proceed to step 4:
The number 66 fits into 29 0 times, leaving a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Subtract 0 from 29 to get 29.
Bring next digit (5) of the dividend behind the 29 and repeat the process: 295 / 66

Going ahead to step 5:
66 goes into 295 4 times with a remainder of 31.
Write down 4 as next digit of the result. 
Result so far: 904.0
If we take 264 away from 295, we end up with 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 66

On to step 6:
If we divide 313 by 66, we get 4 and a remainder of 49.
Use 4 as the next digit of our solution. 
Result so far: 9044.0
If we subtract 264 from 313, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 7:
66 goes into 490 7 times with a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 9044.7
Subtracting 462 from 490 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
If we divide 280 by 66, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 9044.74
Subtract 264 from 280 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
66 can be fit into 160 2 times, resulting in a remainder of 28.
The next digit of our result is 2. 
Result so far: 9044.742
Subtract 132 from 160 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
If we divide 280 by 66, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 9044.7424
Deduct 264 from 280 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
160 divided by 66 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 9044.74242
Subtracting 132 from 160 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 12:
66 goes into 280 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 9044.742424
Subtract 264 from 280 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
66 can be fit into 160 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 9044.7424242
Deduct 132 from 160 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
66 can be fit into 280 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 9044.74242424
If we subtract 264 from 280, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 9044.74242424, and the remainder is 1.6e-08.
