54538449 ÷ 540 
The aim is to understand the frequency of 540 in 54538449.

Step 1:
540 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 540

Moving on to step 2:
540 goes into 54 0 times with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Take the next digit (5) from the dividend and append it to 54, then repeat: 545 / 540

Step 3:
The number 540 fits into 545 1 times, leaving a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 5 after subtracting 540 from 545.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 540

Advancing to step 4:
If we divide 53 by 540, we get 0 and a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 53 and we're left with 53.
Grab the next digit (8) from the dividend, add it to 53, then carry on: 538 / 540

Step 5:
540 goes into 538 0 times with a remainder of 538.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
The remainder is 538 after subtracting 0 from 538.
Take the next digit (4) from the dividend and append it to 538, then repeat: 5384 / 540

On to step 6:
The number 540 fits into 5384 9 times, leaving a remainder of 524.
Use 9 as the next digit of our solution. 
Result so far: 1009.0
If we take 4860 away from 5384, we end up with 524.
Grab the next digit (4) from the dividend, add it to 524, then carry on: 5244 / 540

Advancing to step 7:
540 can be fit into 5244 9 times, resulting in a remainder of 384.
Use 9 as the next digit of our solution. 
Result so far: 10099.0
If we subtract 4860 from 5244, we get 384.
Append the next digit (9) from the dividend to 384 and continue with: 3849 / 540

Let's proceed to step 8:
540 can be fit into 3849 7 times, resulting in a remainder of 69.
The number 7 becomes the next digit in our result. 
Result so far: 100997.0
Subtract 3780 from 3849 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 9:
The number 540 fits into 690 1 times, leaving a remainder of 150.
The next digit of our result is 1. 
Result so far: 100997.1
Subtract 540 from 690 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
The number 540 fits into 1500 2 times, leaving a remainder of 420.
Write down 2 as next digit of the result. 
Result so far: 100997.12
If we take 1080 away from 1500, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 11:
540 goes into 4200 7 times with a remainder of 420.
The next digit of our result is 7. 
Result so far: 100997.127
If we take 3780 away from 4200, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 12:
540 can be fit into 4200 7 times, resulting in a remainder of 420.
The number 7 becomes the next digit in our result. 
Result so far: 100997.1277
If we subtract 3780 from 4200, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

The quotient of the division is 100997.1277, and the remainder is 0.0042.
