72031 ÷ 49 
The aim is to understand the frequency of 49 in 72031.

Advancing to step 1:
When dividing 7 by 49, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 49

Moving on to step 2:
When dividing 72 by 49, we get 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 49 from 72 to get 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 49

Let's proceed to step 3:
49 goes into 230 4 times with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 34 after subtracting 196 from 230.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 49

Let's proceed to step 4:
343 divided by 49 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 147.0
If we subtract 343 from 343, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 49

On to step 5:
The number 49 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 1470.0
If we subtract 0 from 1, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 6:
49 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 1470.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
When dividing 100 by 49, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 1470.02
If we take 98 away from 100, we end up with 2.
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:
The number 49 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 1470.02
If we subtract 0 from 20, we 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:
If we divide 200 by 49, we get 4 and a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 1470.0204
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
40 divided by 49 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1470.0204
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
The number 49 fits into 400 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 1470.020408
Deduct 392 from 400 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
The number 49 fits into 80 1 times, leaving a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1470.0204081
Deduct 49 from 80 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 13:
310 divided by 49 is 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 1470.02040816
The remainder is 16 after subtracting 294 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 1470.02040816 and a remainder of 1.6e-08.
