830139 ÷ 58 
The aim is to understand the frequency of 58 in 830139.

Moving on to step 1:
When dividing 8 by 58, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 58

Going ahead to step 2:
When dividing 83 by 58, we get 1 with a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 58 from 83, we get 25.
Include the next digit (0) from the dividend after 25, then repeat: 250 / 58

Going ahead to step 3:
The number 58 fits into 250 4 times, leaving a remainder of 18.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 232 from 250 to get 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 58

Advancing to step 4:
When dividing 181 by 58, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 143.0
Deduct 174 from 181 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 58

Step 5:
The number 58 fits into 73 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1431.0
If we subtract 58 from 73, we get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 58

Going ahead to step 6:
The number 58 fits into 159 2 times, leaving a remainder of 43.
Write down 2 as next digit of the result. 
Result so far: 14312.0
If we take 116 away from 159, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
58 goes into 430 7 times with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 14312.7
Subtracting 406 from 430 leaves us 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.

Step 8:
If we divide 240 by 58, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 14312.74
Subtract 232 from 240 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
58 can be fit into 80 1 times, resulting in a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 14312.741
If we take 58 away from 80, we end up 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.

Moving on to step 10:
The number 58 fits into 220 3 times, leaving a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 14312.7413
Deduct 174 from 220 and we're left 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.

Advancing to step 11:
460 divided by 58 is 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 14312.74137
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.

Step 12:
58 can be fit into 540 9 times, resulting in a remainder of 18.
The next digit of our result is 9. 
Result so far: 14312.741379
If we subtract 522 from 540, we 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.

On to step 13:
58 can be fit into 180 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 14312.7413793
Subtract 174 from 180 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
58 can be fit into 60 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 14312.74137931
The remainder is 2 after subtracting 58 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 14312.74137931 with a remaining 2e-09.
