We divide 75223819 by 543
The aim is to understand the frequency of 543 in 75223819.

On to step 1:
7 divided by 543 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 543

Let's proceed to step 2:
75 divided by 543 is 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Bring next digit (2) of the dividend behind the 75 and repeat the process: 752 / 543

Going ahead to step 3:
If we divide 752 by 543, we get 1 and a remainder of 209.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 209 after subtracting 543 from 752.
Grab the next digit (2) from the dividend, add it to 209, then carry on: 2092 / 543

Going ahead to step 4:
The number 543 fits into 2092 3 times, leaving a remainder of 463.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 1629 from 2092 to get 463.
Take the next digit (3) from the dividend and append it to 463, then repeat: 4633 / 543

Step 5:
4633 divided by 543 is 8 with a remainder of 289.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
Deduct 4344 from 4633 and we're left with 289.
Append the next digit (8) from the dividend to 289 and continue with: 2898 / 543

On to step 6:
If we divide 2898 by 543, we get 5 and a remainder of 183.
The number 5 becomes the next digit in our result. 
Result so far: 1385.0
Deduct 2715 from 2898 and we're left with 183.
Grab the next digit (1) from the dividend, add it to 183, then carry on: 1831 / 543

On to step 7:
If we divide 1831 by 543, we get 3 and a remainder of 202.
The number 3 becomes the next digit in our result. 
Result so far: 13853.0
The remainder is 202 after subtracting 1629 from 1831.
Take the next digit (9) from the dividend and append it to 202, then repeat: 2029 / 543

Advancing to step 8:
When dividing 2029 by 543, we get 3 with a remainder of 400.
Use 3 as the next digit of our solution. 
Result so far: 138533.0
The remainder is 400 after subtracting 1629 from 2029.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 9:
When dividing 4000 by 543, we get 7 with a remainder of 199.
Put 7 as the next digit of the answer. 
Result so far: 138533.7
Subtract 3801 from 4000 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Step 10:
If we divide 1990 by 543, we get 3 and a remainder of 361.
Write down 3 as next digit of the result. 
Result so far: 138533.73
Subtracting 1629 from 1990 leaves us with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Advancing to step 11:
If we divide 3610 by 543, we get 6 and a remainder of 352.
Put 6 as the next digit of the answer. 
Result so far: 138533.736
If we subtract 3258 from 3610, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 12:
The number 543 fits into 3520 6 times, leaving a remainder of 262.
Use 6 as the next digit of our solution. 
Result so far: 138533.7366
If we subtract 3258 from 3520, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

The quotient of the division is 138533.7366, and the remainder is 0.00262.
