90086526 divided by 564 
The aim is to understand the frequency of 564 in 90086526.

On to step 1:
564 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 564

Going ahead to step 2:
If we divide 90 by 564, we get 0 and a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Append the next digit (0) from the dividend to 90 and continue with: 900 / 564

Let's proceed to step 3:
When dividing 900 by 564, we get 1 with a remainder of 336.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 564 from 900 and we're left with 336.
Fetch the next digit (8) from the dividend, attach it to 336 and continue: 3368 / 564

Moving on to step 4:
When dividing 3368 by 564, we get 5 with a remainder of 548.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 2820 from 3368 leaves us with 548.
Fetch the next digit (6) from the dividend, attach it to 548 and continue: 5486 / 564

Step 5:
564 goes into 5486 9 times with a remainder of 410.
Write down 9 as next digit of the result. 
Result so far: 159.0
The remainder is 410 after subtracting 5076 from 5486.
Append the next digit (5) from the dividend to 410 and continue with: 4105 / 564

Let's proceed to step 6:
564 can be fit into 4105 7 times, resulting in a remainder of 157.
The number 7 becomes the next digit in our result. 
Result so far: 1597.0
Subtract 3948 from 4105 to get 157.
Bring next digit (2) of the dividend behind the 157 and repeat the process: 1572 / 564

Let's proceed to step 7:
564 goes into 1572 2 times with a remainder of 444.
Use 2 as the next digit of our solution. 
Result so far: 15972.0
If we subtract 1128 from 1572, we get 444.
Include the next digit (6) from the dividend after 444, then repeat: 4446 / 564

Let's proceed to step 8:
4446 divided by 564 is 7 with a remainder of 498.
The number 7 becomes the next digit in our result. 
Result so far: 159727.0
Subtracting 3948 from 4446 leaves us with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Going ahead to step 9:
4980 divided by 564 is 8 with a remainder of 468.
Put 8 as the next digit of the answer. 
Result so far: 159727.8
If we subtract 4512 from 4980, we get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

On to step 10:
4680 divided by 564 is 8 with a remainder of 168.
Write down 8 as next digit of the result. 
Result so far: 159727.88
Deduct 4512 from 4680 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

After the division, we end up with 159727.88 and a remainder of 0.168.
