7438028 ÷ 966 
The aim is to understand the frequency of 966 in 7438028.

Step 1:
966 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 966

Going ahead to step 2:
966 goes into 74 0 times with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Include the next digit (3) from the dividend after 74, then repeat: 743 / 966

On to step 3:
When dividing 743 by 966, we get 0 with a remainder of 743.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 743, we get 743.
Bring next digit (8) of the dividend behind the 743 and repeat the process: 7438 / 966

Going ahead to step 4:
966 can be fit into 7438 7 times, resulting in a remainder of 676.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 6762 from 7438, we get 676.
Fetch the next digit (0) from the dividend, attach it to 676 and continue: 6760 / 966

Going ahead to step 5:
6760 divided by 966 is 6 with a remainder of 964.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Deduct 5796 from 6760 and we're left with 964.
Grab the next digit (2) from the dividend, add it to 964, then carry on: 9642 / 966

Moving on to step 6:
When dividing 9642 by 966, we get 9 with a remainder of 948.
The next digit of our result is 9. 
Result so far: 769.0
If we subtract 8694 from 9642, we get 948.
Append the next digit (8) from the dividend to 948 and continue with: 9488 / 966

Advancing to step 7:
If we divide 9488 by 966, we get 9 and a remainder of 794.
Write down 9 as next digit of the result. 
Result so far: 7699.0
Deduct 8694 from 9488 and we're left with 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Let's proceed to step 8:
966 goes into 7940 8 times with a remainder of 212.
Write down 8 as next digit of the result. 
Result so far: 7699.8
If we subtract 7728 from 7940, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 9:
966 goes into 2120 2 times with a remainder of 188.
The next digit of our result is 2. 
Result so far: 7699.82
If we subtract 1932 from 2120, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 10:
966 can be fit into 1880 1 times, resulting in a remainder of 914.
Use 1 as the next digit of our solution. 
Result so far: 7699.821
Subtracting 966 from 1880 leaves us with 914.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9140, and continue the process.

Going ahead to step 11:
If we divide 9140 by 966, we get 9 and a remainder of 446.
Record the quotient 9 as the next digit in the result. 
Result so far: 7699.8219
Subtracting 8694 from 9140 leaves us with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Step 12:
4460 divided by 966 is 4 with a remainder of 596.
Record the quotient 4 as the next digit in the result. 
Result so far: 7699.82194
Deduct 3864 from 4460 and we're left with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 13:
5960 divided by 966 is 6 with a remainder of 164.
The number 6 becomes the next digit in our result. 
Result so far: 7699.821946
Subtracting 5796 from 5960 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 14:
1640 divided by 966 is 1 with a remainder of 674.
The next digit of our result is 1. 
Result so far: 7699.8219461
Subtracting 966 from 1640 leaves us with 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Going ahead to step 15:
6740 divided by 966 is 6 with a remainder of 944.
Record the quotient 6 as the next digit in the result. 
Result so far: 7699.82194616
The remainder is 944 after subtracting 5796 from 6740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9440, and continue the process.

The quotient of the division is 7699.82194616, and the remainder is 9.44e-07.
