We divide 23778789 by 135
The aim is to understand the frequency of 135 in 23778789.

Going ahead to step 1:
135 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 135

Let's proceed to step 2:
135 goes into 23 0 times with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 135

Step 3:
135 can be fit into 237 1 times, resulting in a remainder of 102.
The next digit of our result is 1. 
Result so far: 1.0
If we take 135 away from 237, we end up with 102.
Take the next digit (7) from the dividend and append it to 102, then repeat: 1027 / 135

Advancing to step 4:
If we divide 1027 by 135, we get 7 and a remainder of 82.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 945 from 1027 leaves us with 82.
Take the next digit (8) from the dividend and append it to 82, then repeat: 828 / 135

Step 5:
135 goes into 828 6 times with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 176.0
If we take 810 away from 828, we end up with 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 135

Going ahead to step 6:
If we divide 187 by 135, we get 1 and a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 1761.0
Deduct 135 from 187 and we're left with 52.
Fetch the next digit (8) from the dividend, attach it to 52 and continue: 528 / 135

On to step 7:
135 goes into 528 3 times with a remainder of 123.
The next digit of our result is 3. 
Result so far: 17613.0
If we subtract 405 from 528, we get 123.
Fetch the next digit (9) from the dividend, attach it to 123 and continue: 1239 / 135

Going ahead to step 8:
135 can be fit into 1239 9 times, resulting in a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 176139.0
The remainder is 24 after subtracting 1215 from 1239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
135 goes into 240 1 times with a remainder of 105.
Put 1 as the next digit of the answer. 
Result so far: 176139.1
If we take 135 away from 240, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 10:
When dividing 1050 by 135, we get 7 with a remainder of 105.
The next digit of our result is 7. 
Result so far: 176139.17
The remainder is 105 after subtracting 945 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 11:
135 goes into 1050 7 times with a remainder of 105.
The number 7 becomes the next digit in our result. 
Result so far: 176139.177
If we subtract 945 from 1050, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final outcome is 176139.177, with a leftover of 0.0105.
