We're dividing 18038402 by 67 
The aim is to understand the frequency of 67 in 18038402.

On to step 1:
If we divide 1 by 67, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 67

Step 2:
If we divide 18 by 67, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 67

Advancing to step 3:
The number 67 fits into 180 2 times, leaving a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 134 away from 180, we end up with 46.
Fetch the next digit (3) from the dividend, attach it to 46 and continue: 463 / 67

Going ahead to step 4:
67 can be fit into 463 6 times, resulting in a remainder of 61.
Write down 6 as next digit of the result. 
Result so far: 26.0
Deduct 402 from 463 and we're left with 61.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 67

On to step 5:
The number 67 fits into 618 9 times, leaving a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 269.0
If we take 603 away from 618, we end up with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 67

Advancing to step 6:
The number 67 fits into 154 2 times, leaving a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 2692.0
If we take 134 away from 154, we end up with 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 67

Step 7:
67 can be fit into 200 2 times, resulting in a remainder of 66.
The next digit of our result is 2. 
Result so far: 26922.0
If we take 134 away from 200, we end up with 66.
Append the next digit (2) from the dividend to 66 and continue with: 662 / 67

Advancing to step 8:
When dividing 662 by 67, we get 9 with a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 269229.0
If we take 603 away from 662, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 9:
67 can be fit into 590 8 times, resulting in a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 269229.8
Subtracting 536 from 590 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 10:
67 can be fit into 540 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 269229.88
If we subtract 536 from 540, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 269229.88, and the remainder is 0.004.
