Let's divide 904493 by 72
The aim is to understand the frequency of 72 in 904493.

Advancing to step 1:
72 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 72

Step 2:
72 goes into 90 1 times with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 72 from 90, we get 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 72

Let's proceed to step 3:
72 goes into 184 2 times with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 40 after subtracting 144 from 184.
Include the next digit (4) from the dividend after 40, then repeat: 404 / 72

Let's proceed to step 4:
404 divided by 72 is 5 with a remainder of 44.
Put 5 as the next digit of the answer. 
Result so far: 125.0
Deduct 360 from 404 and we're left with 44.
Fetch the next digit (9) from the dividend, attach it to 44 and continue: 449 / 72

Let's proceed to step 5:
If we divide 449 by 72, we get 6 and a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 1256.0
If we take 432 away from 449, we end up with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 72

Step 6:
The number 72 fits into 173 2 times, leaving a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 12562.0
Subtract 144 from 173 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
72 goes into 290 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 12562.4
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.

Let's proceed to step 8:
72 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 12562.4
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
When dividing 200 by 72, we get 2 with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 12562.402
The remainder is 56 after subtracting 144 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 10:
72 can be fit into 560 7 times, resulting in a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 12562.4027
Deduct 504 from 560 and we're left 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.

On to step 11:
If we divide 560 by 72, we get 7 and a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 12562.40277
The remainder is 56 after subtracting 504 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 12562.40277 and a remainder of 5.6e-05.
