We divide 431573 by 67
The aim is to understand the frequency of 67 in 431573.

Step 1:
4 divided by 67 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 67

Step 2:
If we divide 43 by 67, we get 0 and a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 67

Moving on to step 3:
67 can be fit into 431 6 times, resulting in a remainder of 29.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 402 from 431 to get 29.
Include the next digit (5) from the dividend after 29, then repeat: 295 / 67

On to step 4:
295 divided by 67 is 4 with a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
If we take 268 away from 295, we end up with 27.
Take the next digit (7) from the dividend and append it to 27, then repeat: 277 / 67

Going ahead to step 5:
67 can be fit into 277 4 times, resulting in a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 644.0
Subtract 268 from 277 to get 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 67

On to step 6:
67 can be fit into 93 1 times, resulting in a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 6441.0
Deduct 67 from 93 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
The number 67 fits into 260 3 times, leaving a remainder of 59.
The number 3 becomes the next digit in our result. 
Result so far: 6441.3
Subtracting 201 from 260 leaves us 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 8:
The number 67 fits into 590 8 times, leaving a remainder of 54.
The next digit of our result is 8. 
Result so far: 6441.38
Subtract 536 from 590 to get 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 9:
When dividing 540 by 67, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 6441.388
The remainder is 4 after subtracting 536 from 540.
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 result is 6441.388 with a remainder of 0.0004.
