We look at the division of 94532321 by 966 
The aim is to understand the frequency of 966 in 94532321.

On to step 1:
The number 966 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 966

Let's proceed to step 2:
94 divided by 966 is 0 with a remainder of 94.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 94, we get 94.
Take the next digit (5) from the dividend and append it to 94, then repeat: 945 / 966

Let's proceed to step 3:
966 can be fit into 945 0 times, resulting in a remainder of 945.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 945, we get 945.
Grab the next digit (3) from the dividend, add it to 945, then carry on: 9453 / 966

Moving on to step 4:
If we divide 9453 by 966, we get 9 and a remainder of 759.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 8694 from 9453, we get 759.
Bring next digit (2) of the dividend behind the 759 and repeat the process: 7592 / 966

Going ahead to step 5:
If we divide 7592 by 966, we get 7 and a remainder of 830.
The next digit of our result is 7. 
Result so far: 97.0
Subtract 6762 from 7592 to get 830.
Bring next digit (3) of the dividend behind the 830 and repeat the process: 8303 / 966

Going ahead to step 6:
966 goes into 8303 8 times with a remainder of 575.
The number 8 becomes the next digit in our result. 
Result so far: 978.0
If we subtract 7728 from 8303, we get 575.
Bring next digit (2) of the dividend behind the 575 and repeat the process: 5752 / 966

Advancing to step 7:
The number 966 fits into 5752 5 times, leaving a remainder of 922.
Record the quotient 5 as the next digit in the result. 
Result so far: 9785.0
The remainder is 922 after subtracting 4830 from 5752.
Bring next digit (1) of the dividend behind the 922 and repeat the process: 9221 / 966

Advancing to step 8:
When dividing 9221 by 966, we get 9 with a remainder of 527.
Put 9 as the next digit of the answer. 
Result so far: 97859.0
Subtract 8694 from 9221 to get 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

On to step 9:
The number 966 fits into 5270 5 times, leaving a remainder of 440.
The number 5 becomes the next digit in our result. 
Result so far: 97859.5
The remainder is 440 after subtracting 4830 from 5270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 10:
966 goes into 4400 4 times with a remainder of 536.
Use 4 as the next digit of our solution. 
Result so far: 97859.54
Subtracting 3864 from 4400 leaves us with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Moving on to step 11:
966 can be fit into 5360 5 times, resulting in a remainder of 530.
Use 5 as the next digit of our solution. 
Result so far: 97859.545
Subtracting 4830 from 5360 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Let's proceed to step 12:
When dividing 5300 by 966, we get 5 with a remainder of 470.
Record the quotient 5 as the next digit in the result. 
Result so far: 97859.5455
Deduct 4830 from 5300 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Our division results in 97859.5455 with a remaining 0.0047.
