We're dividing 964336 by 90 
The aim is to understand the frequency of 90 in 964336.

Advancing to step 1:
The number 90 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 90

Advancing to step 2:
90 can be fit into 96 1 times, resulting in a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 90 from 96, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 90

Step 3:
90 goes into 64 0 times with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 64, we get 64.
Grab the next digit (3) from the dividend, add it to 64, then carry on: 643 / 90

Moving on to step 4:
90 can be fit into 643 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 107.0
The remainder is 13 after subtracting 630 from 643.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 90

On to step 5:
133 divided by 90 is 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 1071.0
If we take 90 away from 133, we end up with 43.
Take the next digit (6) from the dividend and append it to 43, then repeat: 436 / 90

Step 6:
When dividing 436 by 90, we get 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 10714.0
Subtract 360 from 436 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 7:
If we divide 760 by 90, we get 8 and a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 10714.8
If we subtract 720 from 760, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
90 can be fit into 400 4 times, resulting in a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 10714.84
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
If we divide 400 by 90, we get 4 and a remainder of 40.
The next digit of our result is 4. 
Result so far: 10714.844
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 10714.844 with a balance of 0.004.
