We look at the division of 47663828 by 663 
The aim is to understand the frequency of 663 in 47663828.

Going ahead to step 1:
4 divided by 663 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 663

Going ahead to step 2:
The number 663 fits into 47 0 times, leaving a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 47 leaves us with 47.
Grab the next digit (6) from the dividend, add it to 47, then carry on: 476 / 663

Advancing to step 3:
476 divided by 663 is 0 with a remainder of 476.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 476 after subtracting 0 from 476.
Include the next digit (6) from the dividend after 476, then repeat: 4766 / 663

Let's proceed to step 4:
4766 divided by 663 is 7 with a remainder of 125.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 4641 from 4766, we get 125.
Append the next digit (3) from the dividend to 125 and continue with: 1253 / 663

Going ahead to step 5:
663 can be fit into 1253 1 times, resulting in a remainder of 590.
Put 1 as the next digit of the answer. 
Result so far: 71.0
The remainder is 590 after subtracting 663 from 1253.
Take the next digit (8) from the dividend and append it to 590, then repeat: 5908 / 663

Moving on to step 6:
If we divide 5908 by 663, we get 8 and a remainder of 604.
The next digit of our result is 8. 
Result so far: 718.0
If we subtract 5304 from 5908, we get 604.
Append the next digit (2) from the dividend to 604 and continue with: 6042 / 663

Advancing to step 7:
When dividing 6042 by 663, we get 9 with a remainder of 75.
Write down 9 as next digit of the result. 
Result so far: 7189.0
Deduct 5967 from 6042 and we're left with 75.
Append the next digit (8) from the dividend to 75 and continue with: 758 / 663

Advancing to step 8:
The number 663 fits into 758 1 times, leaving a remainder of 95.
Put 1 as the next digit of the answer. 
Result so far: 71891.0
The remainder is 95 after subtracting 663 from 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 9:
If we divide 950 by 663, we get 1 and a remainder of 287.
Record the quotient 1 as the next digit in the result. 
Result so far: 71891.1
The remainder is 287 after subtracting 663 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Step 10:
663 goes into 2870 4 times with a remainder of 218.
Put 4 as the next digit of the answer. 
Result so far: 71891.14
Subtract 2652 from 2870 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Moving on to step 11:
When dividing 2180 by 663, we get 3 with a remainder of 191.
The number 3 becomes the next digit in our result. 
Result so far: 71891.143
Subtract 1989 from 2180 to get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Let's proceed to step 12:
663 can be fit into 1910 2 times, resulting in a remainder of 584.
Put 2 as the next digit of the answer. 
Result so far: 71891.1432
Subtract 1326 from 1910 to get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Moving on to step 13:
663 goes into 5840 8 times with a remainder of 536.
Write down 8 as next digit of the result. 
Result so far: 71891.14328
Subtract 5304 from 5840 to get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

On to step 14:
663 can be fit into 5360 8 times, resulting in a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 71891.143288
The remainder is 56 after subtracting 5304 from 5360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 71891.143288 with a remainder of 5.6e-06.
