303764 ÷ 67 
The aim is to understand the frequency of 67 in 303764.

Step 1:
When dividing 3 by 67, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 67

Moving on to step 2:
When dividing 30 by 67, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Grab the next digit (3) from the dividend, add it to 30, then carry on: 303 / 67

Step 3:
303 divided by 67 is 4 with a remainder of 35.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 268 from 303 leaves us with 35.
Include the next digit (7) from the dividend after 35, then repeat: 357 / 67

Moving on to step 4:
The number 67 fits into 357 5 times, leaving a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Deduct 335 from 357 and we're left with 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 67

Advancing to step 5:
If we divide 226 by 67, we get 3 and a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 453.0
If we subtract 201 from 226, we get 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 67

Advancing to step 6:
254 divided by 67 is 3 with a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 4533.0
Deduct 201 from 254 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 7:
The number 67 fits into 530 7 times, leaving a remainder of 61.
Use 7 as the next digit of our solution. 
Result so far: 4533.7
Subtracting 469 from 530 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 8:
67 can be fit into 610 9 times, resulting in a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 4533.79
The remainder is 7 after subtracting 603 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
67 can be fit into 70 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 4533.791
If we subtract 67 from 70, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
If we divide 30 by 67, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 4533.791
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
67 goes into 300 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 4533.79104
Subtracting 268 from 300 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
67 can be fit into 320 4 times, resulting in a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 4533.791044
Deduct 268 from 320 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 4533.791044, with a leftover of 5.2e-06.
