We divide 90835 by 66
The aim is to understand the frequency of 66 in 90835.

Step 1:
66 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 66

Advancing to step 2:
90 divided by 66 is 1 with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 66 from 90, we get 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 66

On to step 3:
When dividing 248 by 66, we get 3 with a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 198 from 248 and we're left with 50.
Take the next digit (3) from the dividend and append it to 50, then repeat: 503 / 66

Going ahead to step 4:
66 goes into 503 7 times with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 137.0
The remainder is 41 after subtracting 462 from 503.
Append the next digit (5) from the dividend to 41 and continue with: 415 / 66

On to step 5:
415 divided by 66 is 6 with a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 1376.0
Deduct 396 from 415 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 6:
If we divide 190 by 66, we get 2 and a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 1376.2
Subtract 132 from 190 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 7:
When dividing 580 by 66, we get 8 with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 1376.28
Deduct 528 from 580 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 8:
520 divided by 66 is 7 with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 1376.287
If we take 462 away from 520, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 9:
66 can be fit into 580 8 times, resulting in a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 1376.2878
Subtracting 528 from 580 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
520 divided by 66 is 7 with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 1376.28787
Deduct 462 from 520 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 11:
66 can be fit into 580 8 times, resulting in a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 1376.287878
Subtract 528 from 580 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 12:
When dividing 520 by 66, we get 7 with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 1376.2878787
Subtracting 462 from 520 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 13:
66 goes into 580 8 times with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 1376.28787878
If we take 528 away from 580, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 1376.28787878 with a remainder of 5.2e-08.
