74432331 ÷ 966 
The aim is to understand the frequency of 966 in 74432331.

Moving on to step 1:
If we divide 7 by 966, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 966

Step 2:
When dividing 74 by 966, we get 0 with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Bring next digit (4) of the dividend behind the 74 and repeat the process: 744 / 966

Going ahead to step 3:
966 goes into 744 0 times with a remainder of 744.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 744 after subtracting 0 from 744.
Take the next digit (3) from the dividend and append it to 744, then repeat: 7443 / 966

Let's proceed to step 4:
The number 966 fits into 7443 7 times, leaving a remainder of 681.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 6762 from 7443 and we're left with 681.
Include the next digit (2) from the dividend after 681, then repeat: 6812 / 966

Step 5:
966 goes into 6812 7 times with a remainder of 50.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
Subtracting 6762 from 6812 leaves us with 50.
Fetch the next digit (3) from the dividend, attach it to 50 and continue: 503 / 966

Advancing to step 6:
When dividing 503 by 966, we get 0 with a remainder of 503.
Record the quotient 0 as the next digit in the result. 
Result so far: 770.0
Deduct 0 from 503 and we're left with 503.
Append the next digit (3) from the dividend to 503 and continue with: 5033 / 966

Moving on to step 7:
If we divide 5033 by 966, we get 5 and a remainder of 203.
Use 5 as the next digit of our solution. 
Result so far: 7705.0
Subtracting 4830 from 5033 leaves us with 203.
Take the next digit (1) from the dividend and append it to 203, then repeat: 2031 / 966

Advancing to step 8:
If we divide 2031 by 966, we get 2 and a remainder of 99.
Put 2 as the next digit of the answer. 
Result so far: 77052.0
The remainder is 99 after subtracting 1932 from 2031.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 9:
If we divide 990 by 966, we get 1 and a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 77052.1
Deduct 966 from 990 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
240 divided by 966 is 0 with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 77052.1
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 11:
966 goes into 2400 2 times with a remainder of 468.
Write down 2 as next digit of the result. 
Result so far: 77052.102
If we subtract 1932 from 2400, we get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Moving on to step 12:
When dividing 4680 by 966, we get 4 with a remainder of 816.
The number 4 becomes the next digit in our result. 
Result so far: 77052.1024
If we subtract 3864 from 4680, we get 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Advancing to step 13:
966 goes into 8160 8 times with a remainder of 432.
Record the quotient 8 as the next digit in the result. 
Result so far: 77052.10248
Subtract 7728 from 8160 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 14:
If we divide 4320 by 966, we get 4 and a remainder of 456.
Write down 4 as next digit of the result. 
Result so far: 77052.102484
Deduct 3864 from 4320 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 15:
If we divide 4560 by 966, we get 4 and a remainder of 696.
Put 4 as the next digit of the answer. 
Result so far: 77052.1024844
If we take 3864 away from 4560, we end up with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

The final result is 77052.1024844 with a remainder of 6.96e-06.
