We look at the division of 66447816 by 947 
The aim is to understand the frequency of 947 in 66447816.

Step 1:
947 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 947

Going ahead to step 2:
If we divide 66 by 947, we get 0 and a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 947

Let's proceed to step 3:
If we divide 664 by 947, we get 0 and a remainder of 664.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 664, we get 664.
Include the next digit (4) from the dividend after 664, then repeat: 6644 / 947

Going ahead to step 4:
The number 947 fits into 6644 7 times, leaving a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 6629 from 6644, we get 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 947

Let's proceed to step 5:
When dividing 157 by 947, we get 0 with a remainder of 157.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
Deduct 0 from 157 and we're left with 157.
Append the next digit (8) from the dividend to 157 and continue with: 1578 / 947

On to step 6:
When dividing 1578 by 947, we get 1 with a remainder of 631.
Write down 1 as next digit of the result. 
Result so far: 701.0
Subtracting 947 from 1578 leaves us with 631.
Take the next digit (1) from the dividend and append it to 631, then repeat: 6311 / 947

Moving on to step 7:
If we divide 6311 by 947, we get 6 and a remainder of 629.
Put 6 as the next digit of the answer. 
Result so far: 7016.0
The remainder is 629 after subtracting 5682 from 6311.
Fetch the next digit (6) from the dividend, attach it to 629 and continue: 6296 / 947

Moving on to step 8:
When dividing 6296 by 947, we get 6 with a remainder of 614.
The number 6 becomes the next digit in our result. 
Result so far: 70166.0
If we take 5682 away from 6296, we end up with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Let's proceed to step 9:
If we divide 6140 by 947, we get 6 and a remainder of 458.
Use 6 as the next digit of our solution. 
Result so far: 70166.6
If we take 5682 away from 6140, we end up with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Moving on to step 10:
If we divide 4580 by 947, we get 4 and a remainder of 792.
The next digit of our result is 4. 
Result so far: 70166.64
The remainder is 792 after subtracting 3788 from 4580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Advancing to step 11:
The number 947 fits into 7920 8 times, leaving a remainder of 344.
Use 8 as the next digit of our solution. 
Result so far: 70166.648
If we subtract 7576 from 7920, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 12:
The number 947 fits into 3440 3 times, leaving a remainder of 599.
The number 3 becomes the next digit in our result. 
Result so far: 70166.6483
Deduct 2841 from 3440 and we're left with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Going ahead to step 13:
The number 947 fits into 5990 6 times, leaving a remainder of 308.
The number 6 becomes the next digit in our result. 
Result so far: 70166.64836
The remainder is 308 after subtracting 5682 from 5990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 14:
947 can be fit into 3080 3 times, resulting in a remainder of 239.
Put 3 as the next digit of the answer. 
Result so far: 70166.648363
Subtract 2841 from 3080 to get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

On to step 15:
When dividing 2390 by 947, we get 2 with a remainder of 496.
The next digit of our result is 2. 
Result so far: 70166.6483632
Subtracting 1894 from 2390 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Moving on to step 16:
4960 divided by 947 is 5 with a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 70166.64836325
Subtracting 4735 from 4960 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

The quotient of the division is 70166.64836325, and the remainder is 2.25e-07.
