54061208 divided by 966 
The aim is to understand the frequency of 966 in 54061208.

On to step 1:
5 divided by 966 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 966

Moving on to step 2:
The number 966 fits into 54 0 times, leaving a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Include the next digit (0) from the dividend after 54, then repeat: 540 / 966

Going ahead to step 3:
540 divided by 966 is 0 with a remainder of 540.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 540 after subtracting 0 from 540.
Bring next digit (6) of the dividend behind the 540 and repeat the process: 5406 / 966

Let's proceed to step 4:
5406 divided by 966 is 5 with a remainder of 576.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 576 after subtracting 4830 from 5406.
Include the next digit (1) from the dividend after 576, then repeat: 5761 / 966

Let's proceed to step 5:
966 can be fit into 5761 5 times, resulting in a remainder of 931.
The next digit of our result is 5. 
Result so far: 55.0
The remainder is 931 after subtracting 4830 from 5761.
Append the next digit (2) from the dividend to 931 and continue with: 9312 / 966

Advancing to step 6:
966 can be fit into 9312 9 times, resulting in a remainder of 618.
Record the quotient 9 as the next digit in the result. 
Result so far: 559.0
If we take 8694 away from 9312, we end up with 618.
Grab the next digit (0) from the dividend, add it to 618, then carry on: 6180 / 966

Moving on to step 7:
The number 966 fits into 6180 6 times, leaving a remainder of 384.
The next digit of our result is 6. 
Result so far: 5596.0
Subtracting 5796 from 6180 leaves us with 384.
Include the next digit (8) from the dividend after 384, then repeat: 3848 / 966

Step 8:
The number 966 fits into 3848 3 times, leaving a remainder of 950.
Write down 3 as next digit of the result. 
Result so far: 55963.0
If we subtract 2898 from 3848, we get 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9500, and continue the process.

Going ahead to step 9:
The number 966 fits into 9500 9 times, leaving a remainder of 806.
The next digit of our result is 9. 
Result so far: 55963.9
If we subtract 8694 from 9500, we get 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Step 10:
If we divide 8060 by 966, we get 8 and a remainder of 332.
Put 8 as the next digit of the answer. 
Result so far: 55963.98
The remainder is 332 after subtracting 7728 from 8060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 11:
When dividing 3320 by 966, we get 3 with a remainder of 422.
Use 3 as the next digit of our solution. 
Result so far: 55963.983
Subtract 2898 from 3320 to get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Step 12:
966 can be fit into 4220 4 times, resulting in a remainder of 356.
Record the quotient 4 as the next digit in the result. 
Result so far: 55963.9834
The remainder is 356 after subtracting 3864 from 4220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 13:
If we divide 3560 by 966, we get 3 and a remainder of 662.
Record the quotient 3 as the next digit in the result. 
Result so far: 55963.98343
Deduct 2898 from 3560 and we're left with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Going ahead to step 14:
If we divide 6620 by 966, we get 6 and a remainder of 824.
Write down 6 as next digit of the result. 
Result so far: 55963.983436
If we subtract 5796 from 6620, we get 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

Let's proceed to step 15:
When dividing 8240 by 966, we get 8 with a remainder of 512.
Record the quotient 8 as the next digit in the result. 
Result so far: 55963.9834368
The remainder is 512 after subtracting 7728 from 8240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Advancing to step 16:
The number 966 fits into 5120 5 times, leaving a remainder of 290.
Use 5 as the next digit of our solution. 
Result so far: 55963.98343685
If we take 4830 away from 5120, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

After the division, we end up with 55963.98343685 and a remainder of 2.9e-07.
