Let's divide 55764 by 90
The aim is to understand the frequency of 90 in 55764.

Let's proceed to step 1:
90 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 90

Going ahead to step 2:
The number 90 fits into 55 0 times, leaving a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Fetch the next digit (7) from the dividend, attach it to 55 and continue: 557 / 90

On to step 3:
If we divide 557 by 90, we get 6 and a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 17 after subtracting 540 from 557.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 90

Going ahead to step 4:
90 goes into 176 1 times with a remainder of 86.
Put 1 as the next digit of the answer. 
Result so far: 61.0
Subtract 90 from 176 to get 86.
Grab the next digit (4) from the dividend, add it to 86, then carry on: 864 / 90

Moving on to step 5:
If we divide 864 by 90, we get 9 and a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 619.0
Subtract 810 from 864 to 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.

Going ahead to step 6:
90 can be fit into 540 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 619.6
If we subtract 540 from 540, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
The number 90 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 619.6
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
The number 90 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 619.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 619.6 and a remainder of 0.0.
