We divide 966131 by 90
The aim is to understand the frequency of 90 in 966131.

Step 1:
9 divided by 90 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 90

Step 2:
When dividing 96 by 90, we get 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 90 away from 96, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 90

Moving on to step 3:
90 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (1) from the dividend, add it to 66, then carry on: 661 / 90

Let's proceed to step 4:
If we divide 661 by 90, we get 7 and a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
If we take 630 away from 661, we end up with 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 90

Step 5:
313 divided by 90 is 3 with a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 1073.0
If we take 270 away from 313, we end up with 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 90

Step 6:
90 goes into 431 4 times with a remainder of 71.
Write down 4 as next digit of the result. 
Result so far: 10734.0
If we take 360 away from 431, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 7:
710 divided by 90 is 7 with a remainder of 80.
The next digit of our result is 7. 
Result so far: 10734.7
Deduct 630 from 710 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 8:
800 divided by 90 is 8 with a remainder of 80.
The next digit of our result is 8. 
Result so far: 10734.78
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 9:
When dividing 800 by 90, we get 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 10734.788
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 10734.788 with a remaining 0.008.
