We divide 90983366 by 135
The aim is to understand the frequency of 135 in 90983366.

Advancing to step 1:
When dividing 9 by 135, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 135

Going ahead to step 2:
If we divide 90 by 135, we get 0 and a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Bring next digit (9) of the dividend behind the 90 and repeat the process: 909 / 135

Step 3:
135 can be fit into 909 6 times, resulting in a remainder of 99.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 810 from 909 to get 99.
Append the next digit (8) from the dividend to 99 and continue with: 998 / 135

Advancing to step 4:
When dividing 998 by 135, we get 7 with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 67.0
If we take 945 away from 998, we end up with 53.
Fetch the next digit (3) from the dividend, attach it to 53 and continue: 533 / 135

Let's proceed to step 5:
The number 135 fits into 533 3 times, leaving a remainder of 128.
The next digit of our result is 3. 
Result so far: 673.0
The remainder is 128 after subtracting 405 from 533.
Grab the next digit (3) from the dividend, add it to 128, then carry on: 1283 / 135

Moving on to step 6:
1283 divided by 135 is 9 with a remainder of 68.
The next digit of our result is 9. 
Result so far: 6739.0
Deduct 1215 from 1283 and we're left with 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 135

On to step 7:
When dividing 686 by 135, we get 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 67395.0
The remainder is 11 after subtracting 675 from 686.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 135

Step 8:
116 divided by 135 is 0 with a remainder of 116.
Put 0 as the next digit of the answer. 
Result so far: 673950.0
Subtracting 0 from 116 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 9:
135 can be fit into 1160 8 times, resulting in a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 673950.8
If we subtract 1080 from 1160, 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.

On to step 10:
800 divided by 135 is 5 with a remainder of 125.
The next digit of our result is 5. 
Result so far: 673950.85
If we take 675 away from 800, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 11:
If we divide 1250 by 135, we get 9 and a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 673950.859
Subtracting 1215 from 1250 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
135 goes into 350 2 times with a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 673950.8592
Deduct 270 from 350 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.

Moving on to step 13:
135 can be fit into 800 5 times, resulting in a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 673950.85925
The remainder is 125 after subtracting 675 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 14:
135 goes into 1250 9 times with a remainder of 35.
The next digit of our result is 9. 
Result so far: 673950.859259
Deduct 1215 from 1250 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 15:
350 divided by 135 is 2 with a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 673950.8592592
If we subtract 270 from 350, 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.

Going ahead to step 16:
135 can be fit into 800 5 times, resulting in a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 673950.85925925
Subtract 675 from 800 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

The final result is 673950.85925925 with a remainder of 1.25e-07.
