Let's divide 15156831 by 89
The aim is to understand the frequency of 89 in 15156831.

Moving on to step 1:
If we divide 1 by 89, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 89

Moving on to step 2:
89 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 89

Moving on to step 3:
89 can be fit into 151 1 times, resulting in a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 89 from 151 and we're left with 62.
Bring next digit (5) of the dividend behind the 62 and repeat the process: 625 / 89

Advancing to step 4:
89 can be fit into 625 7 times, resulting in a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtracting 623 from 625 leaves us with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 89

Advancing to step 5:
If we divide 26 by 89, we get 0 and a remainder of 26.
The next digit of our result is 0. 
Result so far: 170.0
If we subtract 0 from 26, we get 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 89

Let's proceed to step 6:
268 divided by 89 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 1703.0
If we take 267 away from 268, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 89

Let's proceed to step 7:
If we divide 13 by 89, we get 0 and a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 17030.0
Subtract 0 from 13 to get 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 89

Step 8:
89 can be fit into 131 1 times, resulting in a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 170301.0
If we subtract 89 from 131, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
89 can be fit into 420 4 times, resulting in a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 170301.4
The remainder is 64 after subtracting 356 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
640 divided by 89 is 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 170301.47
Subtract 623 from 640 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 11:
89 goes into 170 1 times with a remainder of 81.
The number 1 becomes the next digit in our result. 
Result so far: 170301.471
The remainder is 81 after subtracting 89 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 12:
If we divide 810 by 89, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 170301.4719
Subtracting 801 from 810 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 13:
The number 89 fits into 90 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 170301.47191
The remainder is 1 after subtracting 89 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
The number 89 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 170301.47191
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 15:
If we divide 100 by 89, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 170301.4719101
If we subtract 89 from 100, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 16:
If we divide 110 by 89, we get 1 and a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 170301.47191011
The remainder is 21 after subtracting 89 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 170301.47191011 and a remainder of 2.1e-08.
