Let's divide 68868435 by 663
The aim is to understand the frequency of 663 in 68868435.

On to step 1:
When dividing 6 by 663, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 663

Let's proceed to step 2:
If we divide 68 by 663, we get 0 and a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Grab the next digit (8) from the dividend, add it to 68, then carry on: 688 / 663

On to step 3:
When dividing 688 by 663, we get 1 with a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 663 from 688, we get 25.
Include the next digit (6) from the dividend after 25, then repeat: 256 / 663

Moving on to step 4:
663 can be fit into 256 0 times, resulting in a remainder of 256.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 256 after subtracting 0 from 256.
Include the next digit (8) from the dividend after 256, then repeat: 2568 / 663

Advancing to step 5:
2568 divided by 663 is 3 with a remainder of 579.
Write down 3 as next digit of the result. 
Result so far: 103.0
Subtracting 1989 from 2568 leaves us with 579.
Take the next digit (4) from the dividend and append it to 579, then repeat: 5794 / 663

On to step 6:
663 goes into 5794 8 times with a remainder of 490.
Use 8 as the next digit of our solution. 
Result so far: 1038.0
Subtracting 5304 from 5794 leaves us with 490.
Include the next digit (3) from the dividend after 490, then repeat: 4903 / 663

Going ahead to step 7:
663 goes into 4903 7 times with a remainder of 262.
Put 7 as the next digit of the answer. 
Result so far: 10387.0
Subtracting 4641 from 4903 leaves us with 262.
Include the next digit (5) from the dividend after 262, then repeat: 2625 / 663

Advancing to step 8:
When dividing 2625 by 663, we get 3 with a remainder of 636.
The number 3 becomes the next digit in our result. 
Result so far: 103873.0
Subtract 1989 from 2625 to get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Let's proceed to step 9:
663 can be fit into 6360 9 times, resulting in a remainder of 393.
The next digit of our result is 9. 
Result so far: 103873.9
The remainder is 393 after subtracting 5967 from 6360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Let's proceed to step 10:
663 can be fit into 3930 5 times, resulting in a remainder of 615.
Use 5 as the next digit of our solution. 
Result so far: 103873.95
The remainder is 615 after subtracting 3315 from 3930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

On to step 11:
The number 663 fits into 6150 9 times, leaving a remainder of 183.
Record the quotient 9 as the next digit in the result. 
Result so far: 103873.959
If we subtract 5967 from 6150, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Step 12:
663 goes into 1830 2 times with a remainder of 504.
The next digit of our result is 2. 
Result so far: 103873.9592
Deduct 1326 from 1830 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Going ahead to step 13:
If we divide 5040 by 663, we get 7 and a remainder of 399.
The number 7 becomes the next digit in our result. 
Result so far: 103873.95927
Subtracting 4641 from 5040 leaves us with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Let's proceed to step 14:
When dividing 3990 by 663, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 103873.959276
Deduct 3978 from 3990 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 15:
When dividing 120 by 663, we get 0 with a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 103873.959276
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 16:
663 can be fit into 1200 1 times, resulting in a remainder of 537.
Record the quotient 1 as the next digit in the result. 
Result so far: 103873.95927601
If we take 663 away from 1200, we end up with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

The final result is 103873.95927601 with a remainder of 5.37e-07.
