Let's divide 136414 by 90
The aim is to understand the frequency of 90 in 136414.

Advancing to step 1:
When dividing 1 by 90, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 90

Step 2:
If we divide 13 by 90, we get 0 and a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 90

Step 3:
When dividing 136 by 90, we get 1 with a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 90 from 136 to get 46.
Append the next digit (4) from the dividend to 46 and continue with: 464 / 90

Advancing to step 4:
90 goes into 464 5 times with a remainder of 14.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 450 from 464 leaves us with 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 90

Moving on to step 5:
141 divided by 90 is 1 with a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 151.0
Subtract 90 from 141 to get 51.
Fetch the next digit (4) from the dividend, attach it to 51 and continue: 514 / 90

Advancing to step 6:
The number 90 fits into 514 5 times, leaving a remainder of 64.
Record the quotient 5 as the next digit in the result. 
Result so far: 1515.0
If we subtract 450 from 514, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 7:
The number 90 fits into 640 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 1515.7
Subtracting 630 from 640 leaves us 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.

On to step 8:
The number 90 fits into 100 1 times, leaving a remainder of 10.
The next digit of our result is 1. 
Result so far: 1515.71
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
The number 90 fits into 100 1 times, leaving a remainder of 10.
The next digit of our result is 1. 
Result so far: 1515.711
If we take 90 away from 100, 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.

After the division, we end up with 1515.711 and a remainder of 0.001.
