We divide 78830365 by 663
The aim is to understand the frequency of 663 in 78830365.

Let's proceed to step 1:
If we divide 7 by 663, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 663

On to step 2:
663 can be fit into 78 0 times, resulting in a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (8) from the dividend after 78, then repeat: 788 / 663

On to step 3:
When dividing 788 by 663, we get 1 with a remainder of 125.
The next digit of our result is 1. 
Result so far: 1.0
If we take 663 away from 788, we end up with 125.
Append the next digit (3) from the dividend to 125 and continue with: 1253 / 663

Moving on to step 4:
When dividing 1253 by 663, we get 1 with a remainder of 590.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 590 after subtracting 663 from 1253.
Take the next digit (0) from the dividend and append it to 590, then repeat: 5900 / 663

Step 5:
663 goes into 5900 8 times with a remainder of 596.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
Deduct 5304 from 5900 and we're left with 596.
Include the next digit (3) from the dividend after 596, then repeat: 5963 / 663

On to step 6:
663 can be fit into 5963 8 times, resulting in a remainder of 659.
The next digit of our result is 8. 
Result so far: 1188.0
If we take 5304 away from 5963, we end up with 659.
Append the next digit (6) from the dividend to 659 and continue with: 6596 / 663

Step 7:
6596 divided by 663 is 9 with a remainder of 629.
Put 9 as the next digit of the answer. 
Result so far: 11889.0
Subtracting 5967 from 6596 leaves us with 629.
Include the next digit (5) from the dividend after 629, then repeat: 6295 / 663

Advancing to step 8:
If we divide 6295 by 663, we get 9 and a remainder of 328.
The next digit of our result is 9. 
Result so far: 118899.0
Deduct 5967 from 6295 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 9:
3280 divided by 663 is 4 with a remainder of 628.
Use 4 as the next digit of our solution. 
Result so far: 118899.4
The remainder is 628 after subtracting 2652 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Moving on to step 10:
The number 663 fits into 6280 9 times, leaving a remainder of 313.
The next digit of our result is 9. 
Result so far: 118899.49
The remainder is 313 after subtracting 5967 from 6280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Step 11:
The number 663 fits into 3130 4 times, leaving a remainder of 478.
Put 4 as the next digit of the answer. 
Result so far: 118899.494
If we take 2652 away from 3130, we end up with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Let's proceed to step 12:
When dividing 4780 by 663, we get 7 with a remainder of 139.
The number 7 becomes the next digit in our result. 
Result so far: 118899.4947
The remainder is 139 after subtracting 4641 from 4780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 13:
663 goes into 1390 2 times with a remainder of 64.
The next digit of our result is 2. 
Result so far: 118899.49472
Subtracting 1326 from 1390 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
If we divide 640 by 663, we get 0 and a remainder of 640.
Use 0 as the next digit of our solution. 
Result so far: 118899.49472
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 15:
When dividing 6400 by 663, we get 9 with a remainder of 433.
Use 9 as the next digit of our solution. 
Result so far: 118899.4947209
If we take 5967 away from 6400, we end up with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Advancing to step 16:
663 can be fit into 4330 6 times, resulting in a remainder of 352.
Use 6 as the next digit of our solution. 
Result so far: 118899.49472096
Deduct 3978 from 4330 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

The final result is 118899.49472096 with a remainder of 3.52e-07.
