90358392 divided by 511 
The aim is to understand the frequency of 511 in 90358392.

Going ahead to step 1:
If we divide 9 by 511, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 511

Advancing to step 2:
511 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Take the next digit (3) from the dividend and append it to 90, then repeat: 903 / 511

On to step 3:
If we divide 903 by 511, we get 1 and a remainder of 392.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 392 after subtracting 511 from 903.
Append the next digit (5) from the dividend to 392 and continue with: 3925 / 511

Step 4:
If we divide 3925 by 511, we get 7 and a remainder of 348.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 3577 from 3925 leaves us with 348.
Take the next digit (8) from the dividend and append it to 348, then repeat: 3488 / 511

Step 5:
511 goes into 3488 6 times with a remainder of 422.
Write down 6 as next digit of the result. 
Result so far: 176.0
If we subtract 3066 from 3488, we get 422.
Include the next digit (3) from the dividend after 422, then repeat: 4223 / 511

Moving on to step 6:
When dividing 4223 by 511, we get 8 with a remainder of 135.
Write down 8 as next digit of the result. 
Result so far: 1768.0
The remainder is 135 after subtracting 4088 from 4223.
Include the next digit (9) from the dividend after 135, then repeat: 1359 / 511

Advancing to step 7:
1359 divided by 511 is 2 with a remainder of 337.
Put 2 as the next digit of the answer. 
Result so far: 17682.0
Deduct 1022 from 1359 and we're left with 337.
Include the next digit (2) from the dividend after 337, then repeat: 3372 / 511

Moving on to step 8:
When dividing 3372 by 511, we get 6 with a remainder of 306.
Use 6 as the next digit of our solution. 
Result so far: 176826.0
If we take 3066 away from 3372, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 9:
511 goes into 3060 5 times with a remainder of 505.
Put 5 as the next digit of the answer. 
Result so far: 176826.5
If we subtract 2555 from 3060, we get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Going ahead to step 10:
If we divide 5050 by 511, we get 9 and a remainder of 451.
Write down 9 as next digit of the result. 
Result so far: 176826.59
If we subtract 4599 from 5050, we get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Moving on to step 11:
If we divide 4510 by 511, we get 8 and a remainder of 422.
Use 8 as the next digit of our solution. 
Result so far: 176826.598
The remainder is 422 after subtracting 4088 from 4510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

On to step 12:
If we divide 4220 by 511, we get 8 and a remainder of 132.
Write down 8 as next digit of the result. 
Result so far: 176826.5988
Deduct 4088 from 4220 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Our division results in 176826.5988 with a remaining 0.00132.
