835707 divided by 90 
The aim is to understand the frequency of 90 in 835707.

Step 1:
90 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 90

Let's proceed to step 2:
When dividing 83 by 90, we get 0 with a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Append the next digit (5) from the dividend to 83 and continue with: 835 / 90

Let's proceed to step 3:
The number 90 fits into 835 9 times, leaving a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 810 from 835 and we're left with 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 90

On to step 4:
The number 90 fits into 257 2 times, leaving a remainder of 77.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
Deduct 180 from 257 and we're left with 77.
Bring next digit (0) of the dividend behind the 77 and repeat the process: 770 / 90

Let's proceed to step 5:
When dividing 770 by 90, we get 8 with a remainder of 50.
The next digit of our result is 8. 
Result so far: 928.0
Deduct 720 from 770 and we're left with 50.
Include the next digit (7) from the dividend after 50, then repeat: 507 / 90

Step 6:
90 goes into 507 5 times with a remainder of 57.
Put 5 as the next digit of the answer. 
Result so far: 9285.0
If we take 450 away from 507, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 7:
When dividing 570 by 90, we get 6 with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 9285.6
Subtracting 540 from 570 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
90 goes into 300 3 times with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 9285.63
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
300 divided by 90 is 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 9285.633
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 9285.633 with a balance of 0.003.
