We're dividing 90360536 by 290 
The aim is to understand the frequency of 290 in 90360536.

Moving on to step 1:
If we divide 9 by 290, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 290

Going ahead to step 2:
The number 290 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Append the next digit (3) from the dividend to 90 and continue with: 903 / 290

Step 3:
290 can be fit into 903 3 times, resulting in a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 870 away from 903, we end up with 33.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 290

Moving on to step 4:
When dividing 336 by 290, we get 1 with a remainder of 46.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtracting 290 from 336 leaves us with 46.
Append the next digit (0) from the dividend to 46 and continue with: 460 / 290

On to step 5:
The number 290 fits into 460 1 times, leaving a remainder of 170.
Put 1 as the next digit of the answer. 
Result so far: 311.0
If we take 290 away from 460, we end up with 170.
Fetch the next digit (5) from the dividend, attach it to 170 and continue: 1705 / 290

On to step 6:
If we divide 1705 by 290, we get 5 and a remainder of 255.
Record the quotient 5 as the next digit in the result. 
Result so far: 3115.0
The remainder is 255 after subtracting 1450 from 1705.
Fetch the next digit (3) from the dividend, attach it to 255 and continue: 2553 / 290

Step 7:
290 can be fit into 2553 8 times, resulting in a remainder of 233.
The next digit of our result is 8. 
Result so far: 31158.0
If we subtract 2320 from 2553, we get 233.
Bring next digit (6) of the dividend behind the 233 and repeat the process: 2336 / 290

Moving on to step 8:
When dividing 2336 by 290, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 311588.0
Deduct 2320 from 2336 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
The number 290 fits into 160 0 times, leaving a remainder of 160.
The next digit of our result is 0. 
Result so far: 311588.0
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 10:
1600 divided by 290 is 5 with a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 311588.05
The remainder is 150 after subtracting 1450 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 11:
When dividing 1500 by 290, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 311588.055
Subtracting 1450 from 1500 leaves us 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.

Our division results in 311588.055 with a remaining 0.005.
