36318783 ÷ 581 
The aim is to understand the frequency of 581 in 36318783.

Advancing to step 1:
When dividing 3 by 581, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 581

Going ahead to step 2:
581 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: 0.0
If we take 0 away from 36, we end up with 36.
Fetch the next digit (3) from the dividend, attach it to 36 and continue: 363 / 581

Let's proceed to step 3:
581 goes into 363 0 times with a remainder of 363.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 363 to get 363.
Append the next digit (1) from the dividend to 363 and continue with: 3631 / 581

Advancing to step 4:
If we divide 3631 by 581, we get 6 and a remainder of 145.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 3486 from 3631, we get 145.
Fetch the next digit (8) from the dividend, attach it to 145 and continue: 1458 / 581

Moving on to step 5:
581 can be fit into 1458 2 times, resulting in a remainder of 296.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
If we subtract 1162 from 1458, we get 296.
Take the next digit (7) from the dividend and append it to 296, then repeat: 2967 / 581

Moving on to step 6:
581 goes into 2967 5 times with a remainder of 62.
Record the quotient 5 as the next digit in the result. 
Result so far: 625.0
The remainder is 62 after subtracting 2905 from 2967.
Grab the next digit (8) from the dividend, add it to 62, then carry on: 628 / 581

On to step 7:
The number 581 fits into 628 1 times, leaving a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 6251.0
Subtract 581 from 628 to get 47.
Fetch the next digit (3) from the dividend, attach it to 47 and continue: 473 / 581

Step 8:
473 divided by 581 is 0 with a remainder of 473.
Use 0 as the next digit of our solution. 
Result so far: 62510.0
The remainder is 473 after subtracting 0 from 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Going ahead to step 9:
If we divide 4730 by 581, we get 8 and a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 62510.8
The remainder is 82 after subtracting 4648 from 4730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 10:
581 goes into 820 1 times with a remainder of 239.
The number 1 becomes the next digit in our result. 
Result so far: 62510.81
The remainder is 239 after subtracting 581 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Moving on to step 11:
581 can be fit into 2390 4 times, resulting in a remainder of 66.
The next digit of our result is 4. 
Result so far: 62510.814
Subtracting 2324 from 2390 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 12:
581 goes into 660 1 times with a remainder of 79.
The next digit of our result is 1. 
Result so far: 62510.8141
If we subtract 581 from 660, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 13:
The number 581 fits into 790 1 times, leaving a remainder of 209.
The number 1 becomes the next digit in our result. 
Result so far: 62510.81411
If we take 581 away from 790, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

The final result is 62510.81411 with a remainder of 0.000209.
