73507957 ÷ 540 
The aim is to understand the frequency of 540 in 73507957.

Moving on to step 1:
The number 540 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 540

On to step 2:
When dividing 73 by 540, we get 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Append the next digit (5) from the dividend to 73 and continue with: 735 / 540

Advancing to step 3:
When dividing 735 by 540, we get 1 with a remainder of 195.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 540 from 735 leaves us with 195.
Bring next digit (0) of the dividend behind the 195 and repeat the process: 1950 / 540

Moving on to step 4:
The number 540 fits into 1950 3 times, leaving a remainder of 330.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 1620 from 1950 to get 330.
Take the next digit (7) from the dividend and append it to 330, then repeat: 3307 / 540

Advancing to step 5:
540 goes into 3307 6 times with a remainder of 67.
The number 6 becomes the next digit in our result. 
Result so far: 136.0
If we subtract 3240 from 3307, we get 67.
Include the next digit (9) from the dividend after 67, then repeat: 679 / 540

Step 6:
540 goes into 679 1 times with a remainder of 139.
Put 1 as the next digit of the answer. 
Result so far: 1361.0
Subtracting 540 from 679 leaves us with 139.
Grab the next digit (5) from the dividend, add it to 139, then carry on: 1395 / 540

Step 7:
540 can be fit into 1395 2 times, resulting in a remainder of 315.
The next digit of our result is 2. 
Result so far: 13612.0
Deduct 1080 from 1395 and we're left with 315.
Append the next digit (7) from the dividend to 315 and continue with: 3157 / 540

On to step 8:
540 goes into 3157 5 times with a remainder of 457.
Use 5 as the next digit of our solution. 
Result so far: 136125.0
Deduct 2700 from 3157 and we're left with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Advancing to step 9:
The number 540 fits into 4570 8 times, leaving a remainder of 250.
The number 8 becomes the next digit in our result. 
Result so far: 136125.8
Deduct 4320 from 4570 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 10:
540 can be fit into 2500 4 times, resulting in a remainder of 340.
The next digit of our result is 4. 
Result so far: 136125.84
Deduct 2160 from 2500 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 11:
3400 divided by 540 is 6 with a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 136125.846
The remainder is 160 after subtracting 3240 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 12:
If we divide 1600 by 540, we get 2 and a remainder of 520.
The number 2 becomes the next digit in our result. 
Result so far: 136125.8462
Subtracting 1080 from 1600 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 13:
When dividing 5200 by 540, we get 9 with a remainder of 340.
Record the quotient 9 as the next digit in the result. 
Result so far: 136125.84629
Subtracting 4860 from 5200 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 14:
540 goes into 3400 6 times with a remainder of 160.
The next digit of our result is 6. 
Result so far: 136125.846296
Subtracting 3240 from 3400 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 15:
The number 540 fits into 1600 2 times, leaving a remainder of 520.
Use 2 as the next digit of our solution. 
Result so far: 136125.8462962
Deduct 1080 from 1600 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 16:
540 can be fit into 5200 9 times, resulting in a remainder of 340.
Put 9 as the next digit of the answer. 
Result so far: 136125.84629629
The remainder is 340 after subtracting 4860 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The final result is 136125.84629629 with a remainder of 3.4e-07.
