67576109 divided by 402 
The aim is to understand the frequency of 402 in 67576109.

On to step 1:
6 divided by 402 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 402

Let's proceed to step 2:
402 can be fit into 67 0 times, resulting in a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Take the next digit (5) from the dividend and append it to 67, then repeat: 675 / 402

Going ahead to step 3:
When dividing 675 by 402, we get 1 with a remainder of 273.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 402 away from 675, we end up with 273.
Include the next digit (7) from the dividend after 273, then repeat: 2737 / 402

Let's proceed to step 4:
402 can be fit into 2737 6 times, resulting in a remainder of 325.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 2412 away from 2737, we end up with 325.
Take the next digit (6) from the dividend and append it to 325, then repeat: 3256 / 402

Let's proceed to step 5:
402 can be fit into 3256 8 times, resulting in a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 168.0
If we take 3216 away from 3256, we end up with 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 402

Going ahead to step 6:
402 can be fit into 401 0 times, resulting in a remainder of 401.
The number 0 becomes the next digit in our result. 
Result so far: 1680.0
If we subtract 0 from 401, we get 401.
Include the next digit (0) from the dividend after 401, then repeat: 4010 / 402

Let's proceed to step 7:
4010 divided by 402 is 9 with a remainder of 392.
Put 9 as the next digit of the answer. 
Result so far: 16809.0
Deduct 3618 from 4010 and we're left with 392.
Bring next digit (9) of the dividend behind the 392 and repeat the process: 3929 / 402

On to step 8:
402 goes into 3929 9 times with a remainder of 311.
Record the quotient 9 as the next digit in the result. 
Result so far: 168099.0
Subtract 3618 from 3929 to get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Step 9:
If we divide 3110 by 402, we get 7 and a remainder of 296.
The number 7 becomes the next digit in our result. 
Result so far: 168099.7
If we take 2814 away from 3110, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 10:
If we divide 2960 by 402, we get 7 and a remainder of 146.
Record the quotient 7 as the next digit in the result. 
Result so far: 168099.77
If we take 2814 away from 2960, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

The final outcome is 168099.77, with a leftover of 0.146.
