We're dividing 568913 by 90 
The aim is to understand the frequency of 90 in 568913.

Advancing to step 1:
90 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 90

Moving on to step 2:
56 divided by 90 is 0 with a remainder of 56.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Include the next digit (8) from the dividend after 56, then repeat: 568 / 90

Going ahead to step 3:
90 goes into 568 6 times with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 540 from 568 and we're left with 28.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 90

On to step 4:
The number 90 fits into 289 3 times, leaving a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 63.0
The remainder is 19 after subtracting 270 from 289.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 90

Moving on to step 5:
90 can be fit into 191 2 times, resulting in a remainder of 11.
The next digit of our result is 2. 
Result so far: 632.0
Subtracting 180 from 191 leaves us with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 90

Step 6:
If we divide 113 by 90, we get 1 and a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 6321.0
Subtract 90 from 113 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
90 goes into 230 2 times with a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 6321.2
Subtract 180 from 230 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
90 goes into 500 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 6321.25
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
When dividing 500 by 90, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 6321.255
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 6321.255, and the remainder is 0.005.
