501645 divided by 72 
The aim is to understand the frequency of 72 in 501645.

Moving on to step 1:
If we divide 5 by 72, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 72

Step 2:
72 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 72

Step 3:
If we divide 501 by 72, we get 6 and a remainder of 69.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 432 away from 501, we end up with 69.
Bring next digit (6) of the dividend behind the 69 and repeat the process: 696 / 72

Step 4:
The number 72 fits into 696 9 times, leaving a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 69.0
If we take 648 away from 696, we end up with 48.
Append the next digit (4) from the dividend to 48 and continue with: 484 / 72

Let's proceed to step 5:
The number 72 fits into 484 6 times, leaving a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 696.0
Deduct 432 from 484 and we're left with 52.
Append the next digit (5) from the dividend to 52 and continue with: 525 / 72

Step 6:
525 divided by 72 is 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 6967.0
The remainder is 21 after subtracting 504 from 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
The number 72 fits into 210 2 times, leaving a remainder of 66.
The next digit of our result is 2. 
Result so far: 6967.2
Deduct 144 from 210 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 8:
72 can be fit into 660 9 times, resulting in a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 6967.29
Subtract 648 from 660 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
If we divide 120 by 72, we get 1 and a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 6967.291
If we take 72 away from 120, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
72 goes into 480 6 times with a remainder of 48.
The next digit of our result is 6. 
Result so far: 6967.2916
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.

Advancing to step 11:
480 divided by 72 is 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 6967.29166
The remainder is 48 after subtracting 432 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 6967.29166 with a remainder of 4.8e-05.
