We're dividing 23103314 by 581 
The aim is to understand the frequency of 581 in 23103314.

Step 1:
2 divided by 581 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 581

Moving on to step 2:
When dividing 23 by 581, we get 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 581

Step 3:
The number 581 fits into 231 0 times, leaving a remainder of 231.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 231, we end up with 231.
Append the next digit (0) from the dividend to 231 and continue with: 2310 / 581

Let's proceed to step 4:
581 goes into 2310 3 times with a remainder of 567.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 1743 from 2310 to get 567.
Bring next digit (3) of the dividend behind the 567 and repeat the process: 5673 / 581

Step 5:
581 goes into 5673 9 times with a remainder of 444.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtract 5229 from 5673 to get 444.
Grab the next digit (3) from the dividend, add it to 444, then carry on: 4443 / 581

Going ahead to step 6:
If we divide 4443 by 581, we get 7 and a remainder of 376.
Use 7 as the next digit of our solution. 
Result so far: 397.0
The remainder is 376 after subtracting 4067 from 4443.
Grab the next digit (1) from the dividend, add it to 376, then carry on: 3761 / 581

Moving on to step 7:
3761 divided by 581 is 6 with a remainder of 275.
Write down 6 as next digit of the result. 
Result so far: 3976.0
The remainder is 275 after subtracting 3486 from 3761.
Include the next digit (4) from the dividend after 275, then repeat: 2754 / 581

On to step 8:
The number 581 fits into 2754 4 times, leaving a remainder of 430.
Use 4 as the next digit of our solution. 
Result so far: 39764.0
If we take 2324 away from 2754, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 9:
581 goes into 4300 7 times with a remainder of 233.
Use 7 as the next digit of our solution. 
Result so far: 39764.7
If we take 4067 away from 4300, we end up with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

On to step 10:
If we divide 2330 by 581, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 39764.74
The remainder is 6 after subtracting 2324 from 2330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
If we divide 60 by 581, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 39764.74
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
581 goes into 600 1 times with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 39764.7401
Subtract 581 from 600 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 13:
If we divide 190 by 581, we get 0 and a remainder of 190.
Write down 0 as next digit of the result. 
Result so far: 39764.7401
Subtracting 0 from 190 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 14:
When dividing 1900 by 581, we get 3 with a remainder of 157.
The number 3 becomes the next digit in our result. 
Result so far: 39764.740103
If we subtract 1743 from 1900, we get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 15:
581 goes into 1570 2 times with a remainder of 408.
Write down 2 as next digit of the result. 
Result so far: 39764.7401032
If we take 1162 away from 1570, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 16:
If we divide 4080 by 581, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 39764.74010327
The remainder is 13 after subtracting 4067 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 39764.74010327 with a remaining 1.3e-08.
