We look at the division of 745224 by 67 
The aim is to understand the frequency of 67 in 745224.

Let's proceed to step 1:
7 divided by 67 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 67

Step 2:
74 divided by 67 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 67 from 74 leaves us with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 67

Going ahead to step 3:
The number 67 fits into 75 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 67 away from 75, we end up with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 67

Going ahead to step 4:
82 divided by 67 is 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
Deduct 67 from 82 and we're left with 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 67

Going ahead to step 5:
The number 67 fits into 152 2 times, leaving a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 1112.0
If we take 134 away from 152, we end up with 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 67

On to step 6:
The number 67 fits into 184 2 times, leaving a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 11122.0
Subtracting 134 from 184 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
When dividing 500 by 67, we get 7 with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 11122.7
Deduct 469 from 500 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 8:
When dividing 310 by 67, we get 4 with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 11122.74
The remainder is 42 after subtracting 268 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
67 goes into 420 6 times with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 11122.746
Subtracting 402 from 420 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
If we divide 180 by 67, we get 2 and a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 11122.7462
If we subtract 134 from 180, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
The number 67 fits into 460 6 times, leaving a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 11122.74626
Subtracting 402 from 460 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 12:
67 can be fit into 580 8 times, resulting in a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 11122.746268
Subtracting 536 from 580 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
When dividing 440 by 67, we get 6 with a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 11122.7462686
Deduct 402 from 440 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 14:
67 can be fit into 380 5 times, resulting in a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 11122.74626865
Subtract 335 from 380 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 11122.74626865 with a remainder of 4.5e-08.
