We're dividing 71825027 by 663 
The aim is to understand the frequency of 663 in 71825027.

Step 1:
663 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 663

On to step 2:
663 can be fit into 71 0 times, resulting in a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Take the next digit (8) from the dividend and append it to 71, then repeat: 718 / 663

On to step 3:
663 can be fit into 718 1 times, resulting in a remainder of 55.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 663 from 718 leaves us with 55.
Append the next digit (2) from the dividend to 55 and continue with: 552 / 663

Going ahead to step 4:
663 can be fit into 552 0 times, resulting in a remainder of 552.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 552 after subtracting 0 from 552.
Include the next digit (5) from the dividend after 552, then repeat: 5525 / 663

Let's proceed to step 5:
The number 663 fits into 5525 8 times, leaving a remainder of 221.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Deduct 5304 from 5525 and we're left with 221.
Bring next digit (0) of the dividend behind the 221 and repeat the process: 2210 / 663

Step 6:
The number 663 fits into 2210 3 times, leaving a remainder of 221.
The next digit of our result is 3. 
Result so far: 1083.0
If we take 1989 away from 2210, we end up with 221.
Take the next digit (2) from the dividend and append it to 221, then repeat: 2212 / 663

Going ahead to step 7:
663 can be fit into 2212 3 times, resulting in a remainder of 223.
Write down 3 as next digit of the result. 
Result so far: 10833.0
If we subtract 1989 from 2212, we get 223.
Append the next digit (7) from the dividend to 223 and continue with: 2237 / 663

Moving on to step 8:
If we divide 2237 by 663, we get 3 and a remainder of 248.
Write down 3 as next digit of the result. 
Result so far: 108333.0
Subtract 1989 from 2237 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 9:
2480 divided by 663 is 3 with a remainder of 491.
Use 3 as the next digit of our solution. 
Result so far: 108333.3
Subtracting 1989 from 2480 leaves us with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

On to step 10:
If we divide 4910 by 663, we get 7 and a remainder of 269.
Use 7 as the next digit of our solution. 
Result so far: 108333.37
The remainder is 269 after subtracting 4641 from 4910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

On to step 11:
When dividing 2690 by 663, we get 4 with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 108333.374
The remainder is 38 after subtracting 2652 from 2690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
663 goes into 380 0 times with a remainder of 380.
Use 0 as the next digit of our solution. 
Result so far: 108333.374
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 13:
3800 divided by 663 is 5 with a remainder of 485.
Write down 5 as next digit of the result. 
Result so far: 108333.37405
Subtract 3315 from 3800 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Let's proceed to step 14:
663 goes into 4850 7 times with a remainder of 209.
Write down 7 as next digit of the result. 
Result so far: 108333.374057
Deduct 4641 from 4850 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 15:
When dividing 2090 by 663, we get 3 with a remainder of 101.
Put 3 as the next digit of the answer. 
Result so far: 108333.3740573
If we subtract 1989 from 2090, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 16:
1010 divided by 663 is 1 with a remainder of 347.
Record the quotient 1 as the next digit in the result. 
Result so far: 108333.37405731
If we take 663 away from 1010, we end up with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

The final result is 108333.37405731 with a remainder of 3.47e-07.
