812803 divided by 58 
The aim is to understand the frequency of 58 in 812803.

Moving on to step 1:
58 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 58

On to step 2:
If we divide 81 by 58, we get 1 and a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 58 away from 81, we end up with 23.
Take the next digit (2) from the dividend and append it to 23, then repeat: 232 / 58

On to step 3:
58 goes into 232 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 232 from 232 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 58

Moving on to step 4:
58 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 58

Going ahead to step 5:
80 divided by 58 is 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1401.0
If we take 58 away from 80, we end up with 22.
Append the next digit (3) from the dividend to 22 and continue with: 223 / 58

On to step 6:
223 divided by 58 is 3 with a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 14013.0
Subtracting 174 from 223 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
58 can be fit into 490 8 times, resulting in a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 14013.8
If we subtract 464 from 490, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
If we divide 260 by 58, we get 4 and a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 14013.84
Deduct 232 from 260 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
280 divided by 58 is 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 14013.844
If we subtract 232 from 280, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 14013.844, and the remainder is 0.0048.
