Let's divide 54380661 by 135
The aim is to understand the frequency of 135 in 54380661.

Let's proceed to step 1:
When dividing 5 by 135, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 135

Going ahead to step 2:
The number 135 fits into 54 0 times, leaving a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 135

Advancing to step 3:
135 goes into 543 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 540 from 543 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 135

Advancing to step 4:
If we divide 38 by 135, we get 0 and a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtract 0 from 38 to get 38.
Append the next digit (0) from the dividend to 38 and continue with: 380 / 135

On to step 5:
The number 135 fits into 380 2 times, leaving a remainder of 110.
Write down 2 as next digit of the result. 
Result so far: 402.0
Deduct 270 from 380 and we're left with 110.
Grab the next digit (6) from the dividend, add it to 110, then carry on: 1106 / 135

Let's proceed to step 6:
1106 divided by 135 is 8 with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 4028.0
If we take 1080 away from 1106, we end up with 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 135

Advancing to step 7:
135 goes into 266 1 times with a remainder of 131.
The next digit of our result is 1. 
Result so far: 40281.0
The remainder is 131 after subtracting 135 from 266.
Append the next digit (1) from the dividend to 131 and continue with: 1311 / 135

Let's proceed to step 8:
135 can be fit into 1311 9 times, resulting in a remainder of 96.
The next digit of our result is 9. 
Result so far: 402819.0
If we subtract 1215 from 1311, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 9:
135 can be fit into 960 7 times, resulting in a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 402819.7
If we subtract 945 from 960, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
135 can be fit into 150 1 times, resulting in a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 402819.71
Deduct 135 from 150 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
150 divided by 135 is 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 402819.711
Deduct 135 from 150 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 402819.711 with a remaining 0.0015.
