We divide 319493 by 72
The aim is to understand the frequency of 72 in 319493.

Going ahead to step 1:
When dividing 3 by 72, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 72

On to step 2:
If we divide 31 by 72, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 72

Going ahead to step 3:
If we divide 319 by 72, we get 4 and a remainder of 31.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 288 from 319, we get 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 72

Moving on to step 4:
When dividing 314 by 72, we get 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtracting 288 from 314 leaves us with 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 72

Moving on to step 5:
269 divided by 72 is 3 with a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 443.0
The remainder is 53 after subtracting 216 from 269.
Take the next digit (3) from the dividend and append it to 53, then repeat: 533 / 72

Going ahead to step 6:
72 goes into 533 7 times with a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 4437.0
Deduct 504 from 533 and we're left 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.

Moving on to step 7:
The number 72 fits into 290 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 4437.4
The remainder is 2 after subtracting 288 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
If we divide 20 by 72, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 4437.4
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 72 is 2 with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 4437.402
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.

On to step 10:
If we divide 560 by 72, we get 7 and a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 4437.4027
Subtract 504 from 560 to 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.

Going ahead to step 11:
72 can be fit into 560 7 times, resulting in a remainder of 56.
The next digit of our result is 7. 
Result so far: 4437.40277
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 4437.40277, and the remainder is 5.6e-05.
