We look at the division of 34131208 by 663 
The aim is to understand the frequency of 663 in 34131208.

Let's proceed to step 1:
663 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 663

Going ahead to step 2:
The number 663 fits into 34 0 times, leaving a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Fetch the next digit (1) from the dividend, attach it to 34 and continue: 341 / 663

Moving on to step 3:
When dividing 341 by 663, we get 0 with a remainder of 341.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 341 after subtracting 0 from 341.
Append the next digit (3) from the dividend to 341 and continue with: 3413 / 663

Moving on to step 4:
When dividing 3413 by 663, we get 5 with a remainder of 98.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 3315 from 3413 and we're left with 98.
Include the next digit (1) from the dividend after 98, then repeat: 981 / 663

Step 5:
663 goes into 981 1 times with a remainder of 318.
Use 1 as the next digit of our solution. 
Result so far: 51.0
The remainder is 318 after subtracting 663 from 981.
Take the next digit (2) from the dividend and append it to 318, then repeat: 3182 / 663

Let's proceed to step 6:
If we divide 3182 by 663, we get 4 and a remainder of 530.
Record the quotient 4 as the next digit in the result. 
Result so far: 514.0
Subtracting 2652 from 3182 leaves us with 530.
Grab the next digit (0) from the dividend, add it to 530, then carry on: 5300 / 663

Going ahead to step 7:
The number 663 fits into 5300 7 times, leaving a remainder of 659.
Put 7 as the next digit of the answer. 
Result so far: 5147.0
Subtracting 4641 from 5300 leaves us with 659.
Include the next digit (8) from the dividend after 659, then repeat: 6598 / 663

On to step 8:
When dividing 6598 by 663, we get 9 with a remainder of 631.
Record the quotient 9 as the next digit in the result. 
Result so far: 51479.0
Subtract 5967 from 6598 to get 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

On to step 9:
663 can be fit into 6310 9 times, resulting in a remainder of 343.
Write down 9 as next digit of the result. 
Result so far: 51479.9
If we subtract 5967 from 6310, we get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Step 10:
663 can be fit into 3430 5 times, resulting in a remainder of 115.
Record the quotient 5 as the next digit in the result. 
Result so far: 51479.95
Deduct 3315 from 3430 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 11:
663 can be fit into 1150 1 times, resulting in a remainder of 487.
Use 1 as the next digit of our solution. 
Result so far: 51479.951
The remainder is 487 after subtracting 663 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Advancing to step 12:
663 goes into 4870 7 times with a remainder of 229.
The number 7 becomes the next digit in our result. 
Result so far: 51479.9517
If we subtract 4641 from 4870, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Let's proceed to step 13:
When dividing 2290 by 663, we get 3 with a remainder of 301.
Put 3 as the next digit of the answer. 
Result so far: 51479.95173
Deduct 1989 from 2290 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 14:
663 goes into 3010 4 times with a remainder of 358.
Use 4 as the next digit of our solution. 
Result so far: 51479.951734
Subtract 2652 from 3010 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Moving on to step 15:
663 can be fit into 3580 5 times, resulting in a remainder of 265.
Write down 5 as next digit of the result. 
Result so far: 51479.9517345
If we take 3315 away from 3580, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 16:
When dividing 2650 by 663, we get 3 with a remainder of 661.
Use 3 as the next digit of our solution. 
Result so far: 51479.95173453
Subtract 1989 from 2650 to get 661.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6610, and continue the process.

After the division, we end up with 51479.95173453 and a remainder of 6.61e-07.
