Let's divide 13337017 by 581
The aim is to understand the frequency of 581 in 13337017.

Let's proceed to step 1:
581 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 581

Step 2:
13 divided by 581 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 581

On to step 3:
133 divided by 581 is 0 with a remainder of 133.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 133 after subtracting 0 from 133.
Take the next digit (3) from the dividend and append it to 133, then repeat: 1333 / 581

Advancing to step 4:
581 can be fit into 1333 2 times, resulting in a remainder of 171.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1162 from 1333, we get 171.
Append the next digit (7) from the dividend to 171 and continue with: 1717 / 581

On to step 5:
581 can be fit into 1717 2 times, resulting in a remainder of 555.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we take 1162 away from 1717, we end up with 555.
Take the next digit (0) from the dividend and append it to 555, then repeat: 5550 / 581

Let's proceed to step 6:
The number 581 fits into 5550 9 times, leaving a remainder of 321.
The number 9 becomes the next digit in our result. 
Result so far: 229.0
The remainder is 321 after subtracting 5229 from 5550.
Take the next digit (1) from the dividend and append it to 321, then repeat: 3211 / 581

On to step 7:
581 goes into 3211 5 times with a remainder of 306.
Record the quotient 5 as the next digit in the result. 
Result so far: 2295.0
Subtract 2905 from 3211 to get 306.
Append the next digit (7) from the dividend to 306 and continue with: 3067 / 581

Let's proceed to step 8:
581 can be fit into 3067 5 times, resulting in a remainder of 162.
Put 5 as the next digit of the answer. 
Result so far: 22955.0
If we take 2905 away from 3067, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 9:
The number 581 fits into 1620 2 times, leaving a remainder of 458.
Write down 2 as next digit of the result. 
Result so far: 22955.2
Deduct 1162 from 1620 and we're left with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

On to step 10:
If we divide 4580 by 581, we get 7 and a remainder of 513.
Record the quotient 7 as the next digit in the result. 
Result so far: 22955.27
Deduct 4067 from 4580 and we're left with 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Going ahead to step 11:
If we divide 5130 by 581, we get 8 and a remainder of 482.
Record the quotient 8 as the next digit in the result. 
Result so far: 22955.278
Subtract 4648 from 5130 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Advancing to step 12:
The number 581 fits into 4820 8 times, leaving a remainder of 172.
Write down 8 as next digit of the result. 
Result so far: 22955.2788
If we take 4648 away from 4820, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The final outcome is 22955.2788, with a leftover of 0.00172.
