We're dividing 51643579 by 541 
The aim is to understand the frequency of 541 in 51643579.

Going ahead to step 1:
541 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 541

Step 2:
541 can be fit into 51 0 times, resulting in a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 541

Step 3:
516 divided by 541 is 0 with a remainder of 516.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 516, we end up with 516.
Append the next digit (4) from the dividend to 516 and continue with: 5164 / 541

Going ahead to step 4:
When dividing 5164 by 541, we get 9 with a remainder of 295.
The next digit of our result is 9. 
Result so far: 9.0
If we take 4869 away from 5164, we end up with 295.
Include the next digit (3) from the dividend after 295, then repeat: 2953 / 541

On to step 5:
541 goes into 2953 5 times with a remainder of 248.
The next digit of our result is 5. 
Result so far: 95.0
If we take 2705 away from 2953, we end up with 248.
Bring next digit (5) of the dividend behind the 248 and repeat the process: 2485 / 541

Let's proceed to step 6:
When dividing 2485 by 541, we get 4 with a remainder of 321.
Put 4 as the next digit of the answer. 
Result so far: 954.0
Subtracting 2164 from 2485 leaves us with 321.
Take the next digit (7) from the dividend and append it to 321, then repeat: 3217 / 541

Let's proceed to step 7:
3217 divided by 541 is 5 with a remainder of 512.
Write down 5 as next digit of the result. 
Result so far: 9545.0
Subtract 2705 from 3217 to get 512.
Include the next digit (9) from the dividend after 512, then repeat: 5129 / 541

On to step 8:
If we divide 5129 by 541, we get 9 and a remainder of 260.
Use 9 as the next digit of our solution. 
Result so far: 95459.0
If we subtract 4869 from 5129, we get 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 9:
541 goes into 2600 4 times with a remainder of 436.
Put 4 as the next digit of the answer. 
Result so far: 95459.4
Subtract 2164 from 2600 to get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Let's proceed to step 10:
541 goes into 4360 8 times with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 95459.48
The remainder is 32 after subtracting 4328 from 4360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
320 divided by 541 is 0 with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 95459.48
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 12:
When dividing 3200 by 541, we get 5 with a remainder of 495.
Put 5 as the next digit of the answer. 
Result so far: 95459.4805
Subtract 2705 from 3200 to get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

On to step 13:
The number 541 fits into 4950 9 times, leaving a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 95459.48059
Subtract 4869 from 4950 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 14:
541 goes into 810 1 times with a remainder of 269.
Put 1 as the next digit of the answer. 
Result so far: 95459.480591
If we take 541 away from 810, we end up with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Let's proceed to step 15:
2690 divided by 541 is 4 with a remainder of 526.
The next digit of our result is 4. 
Result so far: 95459.4805914
Deduct 2164 from 2690 and we're left with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Step 16:
If we divide 5260 by 541, we get 9 and a remainder of 391.
The next digit of our result is 9. 
Result so far: 95459.48059149
The remainder is 391 after subtracting 4869 from 5260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

The final outcome is 95459.48059149, with a leftover of 3.91e-07.
