We're dividing 4397243 by 543 
The aim is to understand the frequency of 543 in 4397243.

Going ahead to step 1:
543 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 543

Let's proceed to step 2:
When dividing 43 by 543, we get 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 543

Going ahead to step 3:
543 goes into 439 0 times with a remainder of 439.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 439 leaves us with 439.
Grab the next digit (7) from the dividend, add it to 439, then carry on: 4397 / 543

Let's proceed to step 4:
543 can be fit into 4397 8 times, resulting in a remainder of 53.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 4344 from 4397, we get 53.
Fetch the next digit (2) from the dividend, attach it to 53 and continue: 532 / 543

Advancing to step 5:
If we divide 532 by 543, we get 0 and a remainder of 532.
The next digit of our result is 0. 
Result so far: 80.0
The remainder is 532 after subtracting 0 from 532.
Fetch the next digit (4) from the dividend, attach it to 532 and continue: 5324 / 543

Advancing to step 6:
When dividing 5324 by 543, we get 9 with a remainder of 437.
The next digit of our result is 9. 
Result so far: 809.0
If we subtract 4887 from 5324, we get 437.
Bring next digit (3) of the dividend behind the 437 and repeat the process: 4373 / 543

Let's proceed to step 7:
If we divide 4373 by 543, we get 8 and a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 8098.0
Subtracting 4344 from 4373 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 8:
290 divided by 543 is 0 with a remainder of 290.
The number 0 becomes the next digit in our result. 
Result so far: 8098.0
Subtract 0 from 290 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 9:
2900 divided by 543 is 5 with a remainder of 185.
Record the quotient 5 as the next digit in the result. 
Result so far: 8098.05
If we subtract 2715 from 2900, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 10:
When dividing 1850 by 543, we get 3 with a remainder of 221.
Use 3 as the next digit of our solution. 
Result so far: 8098.053
The remainder is 221 after subtracting 1629 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Going ahead to step 11:
When dividing 2210 by 543, we get 4 with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 8098.0534
Subtracting 2172 from 2210 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
The number 543 fits into 380 0 times, leaving a remainder of 380.
The next digit of our result is 0. 
Result so far: 8098.0534
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 13:
543 goes into 3800 6 times with a remainder of 542.
The next digit of our result is 6. 
Result so far: 8098.053406
Deduct 3258 from 3800 and we're left with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Step 14:
543 can be fit into 5420 9 times, resulting in a remainder of 533.
Write down 9 as next digit of the result. 
Result so far: 8098.0534069
Subtract 4887 from 5420 to get 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Advancing to step 15:
When dividing 5330 by 543, we get 9 with a remainder of 443.
Put 9 as the next digit of the answer. 
Result so far: 8098.05340699
Subtracting 4887 from 5330 leaves us with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Our division results in 8098.05340699 with a remaining 4.43e-07.
