Let's divide 533938 by 90
The aim is to understand the frequency of 90 in 533938.

Moving on to step 1:
When dividing 5 by 90, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 90

Let's proceed to step 2:
90 goes into 53 0 times with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Take the next digit (3) from the dividend and append it to 53, then repeat: 533 / 90

On to step 3:
90 goes into 533 5 times with a remainder of 83.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 83 after subtracting 450 from 533.
Append the next digit (9) from the dividend to 83 and continue with: 839 / 90

Going ahead to step 4:
90 can be fit into 839 9 times, resulting in a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 59.0
If we subtract 810 from 839, we get 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 90

Let's proceed to step 5:
90 can be fit into 293 3 times, resulting in a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 593.0
The remainder is 23 after subtracting 270 from 293.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 90

Advancing to step 6:
When dividing 238 by 90, we get 2 with a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 5932.0
If we subtract 180 from 238, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 7:
When dividing 580 by 90, we get 6 with a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 5932.6
Deduct 540 from 580 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
90 goes into 400 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 5932.64
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
When dividing 400 by 90, we get 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 5932.644
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 5932.644 with a balance of 0.004.
