Let's divide 64897749 by 581
The aim is to understand the frequency of 581 in 64897749.

Advancing to step 1:
If we divide 6 by 581, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 581

Let's proceed to step 2:
581 can be fit into 64 0 times, resulting in a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Include the next digit (8) from the dividend after 64, then repeat: 648 / 581

Let's proceed to step 3:
When dividing 648 by 581, we get 1 with a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 581 away from 648, we end up with 67.
Append the next digit (9) from the dividend to 67 and continue with: 679 / 581

Let's proceed to step 4:
581 can be fit into 679 1 times, resulting in a remainder of 98.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 581 away from 679, we end up with 98.
Take the next digit (7) from the dividend and append it to 98, then repeat: 987 / 581

On to step 5:
When dividing 987 by 581, we get 1 with a remainder of 406.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
If we take 581 away from 987, we end up with 406.
Bring next digit (7) of the dividend behind the 406 and repeat the process: 4067 / 581

Step 6:
If we divide 4067 by 581, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 1117.0
If we take 4067 away from 4067, we end up with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 581

Step 7:
If we divide 4 by 581, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 11170.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 581

Moving on to step 8:
581 can be fit into 49 0 times, resulting in a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 111700.0
If we subtract 0 from 49, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 9:
The number 581 fits into 490 0 times, leaving a remainder of 490.
The next digit of our result is 0. 
Result so far: 111700.0
The remainder is 490 after subtracting 0 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 10:
The number 581 fits into 4900 8 times, leaving a remainder of 252.
The next digit of our result is 8. 
Result so far: 111700.08
Subtract 4648 from 4900 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 11:
581 goes into 2520 4 times with a remainder of 196.
Write down 4 as next digit of the result. 
Result so far: 111700.084
Subtract 2324 from 2520 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 12:
When dividing 1960 by 581, we get 3 with a remainder of 217.
The next digit of our result is 3. 
Result so far: 111700.0843
If we take 1743 away from 1960, we end up with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Moving on to step 13:
When dividing 2170 by 581, we get 3 with a remainder of 427.
The next digit of our result is 3. 
Result so far: 111700.08433
If we take 1743 away from 2170, we end up with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

After the division, we end up with 111700.08433 and a remainder of 0.000427.
