558543 divided by 72 
The aim is to understand the frequency of 72 in 558543.

Going ahead to step 1:
If we divide 5 by 72, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 72

Moving on to step 2:
The number 72 fits into 55 0 times, leaving a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Append the next digit (8) from the dividend to 55 and continue with: 558 / 72

Going ahead to step 3:
If we divide 558 by 72, we get 7 and a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 504 from 558 and we're left with 54.
Grab the next digit (5) from the dividend, add it to 54, then carry on: 545 / 72

Step 4:
The number 72 fits into 545 7 times, leaving a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 77.0
Subtracting 504 from 545 leaves us with 41.
Grab the next digit (4) from the dividend, add it to 41, then carry on: 414 / 72

Going ahead to step 5:
If we divide 414 by 72, we get 5 and a remainder of 54.
Put 5 as the next digit of the answer. 
Result so far: 775.0
Subtracting 360 from 414 leaves us with 54.
Fetch the next digit (3) from the dividend, attach it to 54 and continue: 543 / 72

On to step 6:
The number 72 fits into 543 7 times, leaving a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 7757.0
The remainder is 39 after subtracting 504 from 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
When dividing 390 by 72, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 7757.5
The remainder is 30 after subtracting 360 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
If we divide 300 by 72, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 7757.54
Deduct 288 from 300 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
If we divide 120 by 72, we get 1 and a remainder of 48.
Use 1 as the next digit of our solution. 
Result so far: 7757.541
The remainder is 48 after subtracting 72 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
When dividing 480 by 72, we get 6 with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 7757.5416
Subtract 432 from 480 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
If we divide 480 by 72, we get 6 and a remainder of 48.
The next digit of our result is 6. 
Result so far: 7757.54166
Subtract 432 from 480 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 7757.54166, and the remainder is 4.8e-05.
