Let's divide 525857 by 72
The aim is to understand the frequency of 72 in 525857.

Step 1:
If we divide 5 by 72, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 72

Let's proceed to step 2:
72 can be fit into 52 0 times, resulting in a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Bring next digit (5) of the dividend behind the 52 and repeat the process: 525 / 72

Let's proceed to step 3:
72 goes into 525 7 times with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 504 from 525 and we're left with 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 72

Moving on to step 4:
When dividing 218 by 72, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
The remainder is 2 after subtracting 216 from 218.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 72

Moving on to step 5:
When dividing 25 by 72, we get 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 730.0
If we subtract 0 from 25, we get 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 72

On to step 6:
If we divide 257 by 72, we get 3 and a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 7303.0
Deduct 216 from 257 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
410 divided by 72 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 7303.5
Deduct 360 from 410 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
If we divide 500 by 72, we get 6 and a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 7303.56
If we take 432 away from 500, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 9:
When dividing 680 by 72, we get 9 with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 7303.569
Deduct 648 from 680 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
320 divided by 72 is 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 7303.5694
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
320 divided by 72 is 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 7303.56944
Deduct 288 from 320 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 7303.56944, and the remainder is 3.2e-05.
