54078712 ÷ 135 
The aim is to understand the frequency of 135 in 54078712.

Advancing to step 1:
If we divide 5 by 135, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 135

Moving on to step 2:
135 can be fit into 54 0 times, resulting in a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Grab the next digit (0) from the dividend, add it to 54, then carry on: 540 / 135

Step 3:
When dividing 540 by 135, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 540 away from 540, we end up with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 135

Going ahead to step 4:
7 divided by 135 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 135

Let's proceed to step 5:
If we divide 78 by 135, we get 0 and a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 400.0
If we subtract 0 from 78, we get 78.
Take the next digit (7) from the dividend and append it to 78, then repeat: 787 / 135

Advancing to step 6:
135 can be fit into 787 5 times, resulting in a remainder of 112.
Record the quotient 5 as the next digit in the result. 
Result so far: 4005.0
Subtract 675 from 787 to get 112.
Fetch the next digit (1) from the dividend, attach it to 112 and continue: 1121 / 135

On to step 7:
If we divide 1121 by 135, we get 8 and a remainder of 41.
Put 8 as the next digit of the answer. 
Result so far: 40058.0
Subtract 1080 from 1121 to get 41.
Grab the next digit (2) from the dividend, add it to 41, then carry on: 412 / 135

On to step 8:
412 divided by 135 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 400583.0
Subtract 405 from 412 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
If we divide 70 by 135, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 400583.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
The number 135 fits into 700 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 400583.05
The remainder is 25 after subtracting 675 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
250 divided by 135 is 1 with a remainder of 115.
Put 1 as the next digit of the answer. 
Result so far: 400583.051
Deduct 135 from 250 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 12:
When dividing 1150 by 135, we get 8 with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 400583.0518
The remainder is 70 after subtracting 1080 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 13:
The number 135 fits into 700 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 400583.05185
If we subtract 675 from 700, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 14:
When dividing 250 by 135, we get 1 with a remainder of 115.
The number 1 becomes the next digit in our result. 
Result so far: 400583.051851
Deduct 135 from 250 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 15:
1150 divided by 135 is 8 with a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 400583.0518518
The remainder is 70 after subtracting 1080 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 16:
135 can be fit into 700 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 400583.05185185
Subtract 675 from 700 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 400583.05185185, and the remainder is 2.5e-08.
