We're dividing 51561953 by 540 
The aim is to understand the frequency of 540 in 51561953.

Moving on to step 1:
540 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 540

Advancing to step 2:
540 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 540

Going ahead to step 3:
When dividing 515 by 540, we get 0 with a remainder of 515.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 515, we get 515.
Take the next digit (6) from the dividend and append it to 515, then repeat: 5156 / 540

Going ahead to step 4:
If we divide 5156 by 540, we get 9 and a remainder of 296.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 4860 from 5156, we get 296.
Append the next digit (1) from the dividend to 296 and continue with: 2961 / 540

Moving on to step 5:
If we divide 2961 by 540, we get 5 and a remainder of 261.
The next digit of our result is 5. 
Result so far: 95.0
Deduct 2700 from 2961 and we're left with 261.
Fetch the next digit (9) from the dividend, attach it to 261 and continue: 2619 / 540

Moving on to step 6:
2619 divided by 540 is 4 with a remainder of 459.
Use 4 as the next digit of our solution. 
Result so far: 954.0
Deduct 2160 from 2619 and we're left with 459.
Include the next digit (5) from the dividend after 459, then repeat: 4595 / 540

On to step 7:
The number 540 fits into 4595 8 times, leaving a remainder of 275.
Record the quotient 8 as the next digit in the result. 
Result so far: 9548.0
If we take 4320 away from 4595, we end up with 275.
Bring next digit (3) of the dividend behind the 275 and repeat the process: 2753 / 540

Advancing to step 8:
The number 540 fits into 2753 5 times, leaving a remainder of 53.
Write down 5 as next digit of the result. 
Result so far: 95485.0
If we subtract 2700 from 2753, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 9:
If we divide 530 by 540, we get 0 and a remainder of 530.
Use 0 as the next digit of our solution. 
Result so far: 95485.0
Subtracting 0 from 530 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 10:
540 can be fit into 5300 9 times, resulting in a remainder of 440.
The next digit of our result is 9. 
Result so far: 95485.09
Subtracting 4860 from 5300 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 11:
The number 540 fits into 4400 8 times, leaving a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 95485.098
Subtracting 4320 from 4400 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
800 divided by 540 is 1 with a remainder of 260.
Record the quotient 1 as the next digit in the result. 
Result so far: 95485.0981
Subtracting 540 from 800 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 13:
540 goes into 2600 4 times with a remainder of 440.
Record the quotient 4 as the next digit in the result. 
Result so far: 95485.09814
If we take 2160 away from 2600, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 14:
If we divide 4400 by 540, we get 8 and a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 95485.098148
Subtracting 4320 from 4400 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
540 goes into 800 1 times with a remainder of 260.
The number 1 becomes the next digit in our result. 
Result so far: 95485.0981481
The remainder is 260 after subtracting 540 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 16:
When dividing 2600 by 540, we get 4 with a remainder of 440.
Use 4 as the next digit of our solution. 
Result so far: 95485.09814814
Subtract 2160 from 2600 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

In conclusion, the division gives 95485.09814814 with a balance of 4.4e-07.
