We look at the division of 13899878 by 158 
The aim is to understand the frequency of 158 in 13899878.

Step 1:
158 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 158

Moving on to step 2:
If we divide 13 by 158, we get 0 and a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 158

On to step 3:
138 divided by 158 is 0 with a remainder of 138.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 138 to get 138.
Append the next digit (9) from the dividend to 138 and continue with: 1389 / 158

Going ahead to step 4:
The number 158 fits into 1389 8 times, leaving a remainder of 125.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 1264 from 1389 to get 125.
Take the next digit (9) from the dividend and append it to 125, then repeat: 1259 / 158

Going ahead to step 5:
158 goes into 1259 7 times with a remainder of 153.
Write down 7 as next digit of the result. 
Result so far: 87.0
Subtracting 1106 from 1259 leaves us with 153.
Include the next digit (8) from the dividend after 153, then repeat: 1538 / 158

Moving on to step 6:
The number 158 fits into 1538 9 times, leaving a remainder of 116.
Write down 9 as next digit of the result. 
Result so far: 879.0
Deduct 1422 from 1538 and we're left with 116.
Include the next digit (7) from the dividend after 116, then repeat: 1167 / 158

On to step 7:
The number 158 fits into 1167 7 times, leaving a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 8797.0
If we subtract 1106 from 1167, we get 61.
Fetch the next digit (8) from the dividend, attach it to 61 and continue: 618 / 158

Moving on to step 8:
618 divided by 158 is 3 with a remainder of 144.
Put 3 as the next digit of the answer. 
Result so far: 87973.0
The remainder is 144 after subtracting 474 from 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 9:
If we divide 1440 by 158, we get 9 and a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 87973.9
If we subtract 1422 from 1440, 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.

Let's proceed to step 10:
180 divided by 158 is 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 87973.91
Subtracting 158 from 180 leaves us 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.

Advancing to step 11:
If we divide 220 by 158, we get 1 and a remainder of 62.
The next digit of our result is 1. 
Result so far: 87973.911
If we take 158 away from 220, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

In conclusion, the division gives 87973.911 with a balance of 0.0062.
