We look at the division of 543051 by 67 
The aim is to understand the frequency of 67 in 543051.

Going ahead to step 1:
When dividing 5 by 67, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 67

Advancing to step 2:
54 divided by 67 is 0 with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 67

Let's proceed to step 3:
67 can be fit into 543 8 times, resulting in a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 7 after subtracting 536 from 543.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 67

Let's proceed to step 4:
67 goes into 70 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 81.0
Subtract 67 from 70 to get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 67

Advancing to step 5:
If we divide 35 by 67, we get 0 and a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 810.0
If we subtract 0 from 35, we get 35.
Bring next digit (1) of the dividend behind the 35 and repeat the process: 351 / 67

Let's proceed to step 6:
67 goes into 351 5 times with a remainder of 16.
The next digit of our result is 5. 
Result so far: 8105.0
If we take 335 away from 351, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
If we divide 160 by 67, we get 2 and a remainder of 26.
The next digit of our result is 2. 
Result so far: 8105.2
If we subtract 134 from 160, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
If we divide 260 by 67, we get 3 and a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 8105.23
If we take 201 away from 260, 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.
Put 8 as the next digit of the answer. 
Result so far: 8105.238
Deduct 536 from 590 and we're left 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.

Step 10:
The number 67 fits into 540 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 8105.2388
Subtracting 536 from 540 leaves us with 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 final outcome is 8105.2388, with a leftover of 4e-05.
