403142 divided by 72 
The aim is to understand the frequency of 72 in 403142.

Let's proceed to step 1:
4 divided by 72 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 72

Step 2:
40 divided by 72 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 72

Let's proceed to step 3:
When dividing 403 by 72, we get 5 with a remainder of 43.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 360 from 403, we get 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 72

Going ahead to step 4:
72 can be fit into 431 5 times, resulting in a remainder of 71.
Use 5 as the next digit of our solution. 
Result so far: 55.0
If we take 360 away from 431, we end up with 71.
Fetch the next digit (4) from the dividend, attach it to 71 and continue: 714 / 72

Moving on to step 5:
72 goes into 714 9 times with a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 559.0
Subtracting 648 from 714 leaves us with 66.
Take the next digit (2) from the dividend and append it to 66, then repeat: 662 / 72

Going ahead to step 6:
662 divided by 72 is 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 5599.0
Deduct 648 from 662 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
72 can be fit into 140 1 times, resulting in a remainder of 68.
Write down 1 as next digit of the result. 
Result so far: 5599.1
Subtracting 72 from 140 leaves us 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.

Step 8:
If we divide 680 by 72, we get 9 and a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 5599.19
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.

Going ahead to step 9:
320 divided by 72 is 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 5599.194
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.

Moving on to step 10:
72 goes into 320 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 5599.1944
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.

After the division, we end up with 5599.1944 and a remainder of 0.00032.
