We look at the division of 883872 by 58 
The aim is to understand the frequency of 58 in 883872.

Advancing to step 1:
If we divide 8 by 58, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 58

Going ahead to step 2:
88 divided by 58 is 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 58 from 88, we get 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 58

Let's proceed to step 3:
58 goes into 303 5 times with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 13 after subtracting 290 from 303.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 58

Let's proceed to step 4:
58 can be fit into 138 2 times, resulting in a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 152.0
Subtract 116 from 138 to get 22.
Bring next digit (7) of the dividend behind the 22 and repeat the process: 227 / 58

Advancing to step 5:
The number 58 fits into 227 3 times, leaving a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 1523.0
Deduct 174 from 227 and we're left with 53.
Include the next digit (2) from the dividend after 53, then repeat: 532 / 58

Step 6:
When dividing 532 by 58, we get 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 15239.0
If we take 522 away from 532, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 58, we get 1 and a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 15239.1
If we take 58 away from 100, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
If we divide 420 by 58, we get 7 and a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 15239.17
Subtracting 406 from 420 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
The number 58 fits into 140 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 15239.172
Deduct 116 from 140 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
When dividing 240 by 58, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 15239.1724
Subtracting 232 from 240 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
If we divide 80 by 58, we get 1 and a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 15239.17241
Deduct 58 from 80 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
When dividing 220 by 58, we get 3 with a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 15239.172413
If we take 174 away from 220, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 13:
If we divide 460 by 58, we get 7 and a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 15239.1724137
If we subtract 406 from 460, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 14:
540 divided by 58 is 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 15239.17241379
Subtract 522 from 540 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 15239.17241379 and a remainder of 1.8e-08.
