We divide 967590 by 66
The aim is to understand the frequency of 66 in 967590.

Going ahead to step 1:
The number 66 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 66

On to step 2:
When dividing 96 by 66, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 66 from 96 and we're left with 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 66

Going ahead to step 3:
307 divided by 66 is 4 with a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 264 away from 307, we end up with 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 66

Advancing to step 4:
66 goes into 435 6 times with a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 146.0
If we subtract 396 from 435, we get 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 66

Step 5:
66 can be fit into 399 6 times, resulting in a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 1466.0
Subtracting 396 from 399 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 66

Step 6:
The number 66 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 14660.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
66 goes into 300 4 times with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 14660.4
Deduct 264 from 300 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 14660.45
If we take 330 away from 360, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
The number 66 fits into 300 4 times, leaving a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 14660.454
If we subtract 264 from 300, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
360 divided by 66 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 14660.4545
If we subtract 330 from 360, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
When dividing 300 by 66, we get 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 14660.45454
Deduct 264 from 300 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
If we divide 360 by 66, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 14660.454545
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
66 goes into 300 4 times with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 14660.4545454
Subtracting 264 from 300 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
When dividing 360 by 66, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 14660.45454545
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 14660.45454545 with a balance of 3e-08.
