40197665 ÷ 72 
The aim is to understand the frequency of 72 in 40197665.

Step 1:
The number 72 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 72

On to step 2:
72 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 72

Let's proceed to step 3:
401 divided by 72 is 5 with a remainder of 41.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 360 from 401 and we're left with 41.
Bring next digit (9) of the dividend behind the 41 and repeat the process: 419 / 72

On to step 4:
When dividing 419 by 72, we get 5 with a remainder of 59.
The next digit of our result is 5. 
Result so far: 55.0
Subtracting 360 from 419 leaves us with 59.
Fetch the next digit (7) from the dividend, attach it to 59 and continue: 597 / 72

Let's proceed to step 5:
The number 72 fits into 597 8 times, leaving a remainder of 21.
The next digit of our result is 8. 
Result so far: 558.0
Subtract 576 from 597 to get 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 72

On to step 6:
72 goes into 216 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 5583.0
Deduct 216 from 216 and we're left with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 72

Let's proceed to step 7:
72 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 55830.0
Subtract 0 from 6 to get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 72

Step 8:
If we divide 65 by 72, we get 0 and a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 558300.0
The remainder is 65 after subtracting 0 from 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 9:
If we divide 650 by 72, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 558300.9
The remainder is 2 after subtracting 648 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
When dividing 20 by 72, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 558300.9
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
72 goes into 200 2 times with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 558300.902
If we subtract 144 from 200, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 12:
560 divided by 72 is 7 with a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 558300.9027
If we take 504 away from 560, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
72 goes into 560 7 times with a remainder of 56.
Use 7 as the next digit of our solution. 
Result so far: 558300.90277
If we subtract 504 from 560, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 558300.90277, and the remainder is 5.6e-05.
