Let's divide 14386962 by 641
The aim is to understand the frequency of 641 in 14386962.

Step 1:
If we divide 1 by 641, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 641

On to step 2:
641 goes into 14 0 times with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 641

Step 3:
If we divide 143 by 641, we get 0 and a remainder of 143.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 143, we get 143.
Take the next digit (8) from the dividend and append it to 143, then repeat: 1438 / 641

Advancing to step 4:
641 goes into 1438 2 times with a remainder of 156.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1282 from 1438, we get 156.
Bring next digit (6) of the dividend behind the 156 and repeat the process: 1566 / 641

Let's proceed to step 5:
If we divide 1566 by 641, we get 2 and a remainder of 284.
Use 2 as the next digit of our solution. 
Result so far: 22.0
The remainder is 284 after subtracting 1282 from 1566.
Append the next digit (9) from the dividend to 284 and continue with: 2849 / 641

Step 6:
The number 641 fits into 2849 4 times, leaving a remainder of 285.
The next digit of our result is 4. 
Result so far: 224.0
Subtract 2564 from 2849 to get 285.
Fetch the next digit (6) from the dividend, attach it to 285 and continue: 2856 / 641

On to step 7:
641 can be fit into 2856 4 times, resulting in a remainder of 292.
Put 4 as the next digit of the answer. 
Result so far: 2244.0
Subtracting 2564 from 2856 leaves us with 292.
Fetch the next digit (2) from the dividend, attach it to 292 and continue: 2922 / 641

Moving on to step 8:
When dividing 2922 by 641, we get 4 with a remainder of 358.
The next digit of our result is 4. 
Result so far: 22444.0
Subtract 2564 from 2922 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Step 9:
641 goes into 3580 5 times with a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 22444.5
The remainder is 375 after subtracting 3205 from 3580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 10:
641 goes into 3750 5 times with a remainder of 545.
The number 5 becomes the next digit in our result. 
Result so far: 22444.55
If we subtract 3205 from 3750, we get 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

The final result is 22444.55 with a remainder of 0.545.
