18262086 ÷ 577 
The aim is to understand the frequency of 577 in 18262086.

Let's proceed to step 1:
When dividing 1 by 577, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 577

On to step 2:
577 can be fit into 18 0 times, resulting in a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Take the next digit (2) from the dividend and append it to 18, then repeat: 182 / 577

Step 3:
577 can be fit into 182 0 times, resulting in a remainder of 182.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 182, we get 182.
Append the next digit (6) from the dividend to 182 and continue with: 1826 / 577

Advancing to step 4:
If we divide 1826 by 577, we get 3 and a remainder of 95.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 95 after subtracting 1731 from 1826.
Fetch the next digit (2) from the dividend, attach it to 95 and continue: 952 / 577

On to step 5:
When dividing 952 by 577, we get 1 with a remainder of 375.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
The remainder is 375 after subtracting 577 from 952.
Append the next digit (0) from the dividend to 375 and continue with: 3750 / 577

Step 6:
The number 577 fits into 3750 6 times, leaving a remainder of 288.
Put 6 as the next digit of the answer. 
Result so far: 316.0
If we subtract 3462 from 3750, we get 288.
Grab the next digit (8) from the dividend, add it to 288, then carry on: 2888 / 577

Moving on to step 7:
577 can be fit into 2888 5 times, resulting in a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 3165.0
Subtracting 2885 from 2888 leaves us with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 577

Let's proceed to step 8:
577 can be fit into 36 0 times, resulting in a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 31650.0
Deduct 0 from 36 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
577 goes into 360 0 times with a remainder of 360.
Put 0 as the next digit of the answer. 
Result so far: 31650.0
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 10:
When dividing 3600 by 577, we get 6 with a remainder of 138.
Write down 6 as next digit of the result. 
Result so far: 31650.06
Subtracting 3462 from 3600 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 11:
If we divide 1380 by 577, we get 2 and a remainder of 226.
Use 2 as the next digit of our solution. 
Result so far: 31650.062
The remainder is 226 after subtracting 1154 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Let's proceed to step 12:
2260 divided by 577 is 3 with a remainder of 529.
The next digit of our result is 3. 
Result so far: 31650.0623
If we subtract 1731 from 2260, we get 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Let's proceed to step 13:
The number 577 fits into 5290 9 times, leaving a remainder of 97.
Record the quotient 9 as the next digit in the result. 
Result so far: 31650.06239
Subtract 5193 from 5290 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

On to step 14:
577 can be fit into 970 1 times, resulting in a remainder of 393.
Write down 1 as next digit of the result. 
Result so far: 31650.062391
Deduct 577 from 970 and we're left with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

On to step 15:
3930 divided by 577 is 6 with a remainder of 468.
The number 6 becomes the next digit in our result. 
Result so far: 31650.0623916
Subtract 3462 from 3930 to get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 16:
When dividing 4680 by 577, we get 8 with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 31650.06239168
The remainder is 64 after subtracting 4616 from 4680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 31650.06239168 and a remainder of 6.4e-08.
