31530 divided by 49 
The aim is to understand the frequency of 49 in 31530.

Advancing to step 1:
When dividing 3 by 49, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 49

Let's proceed to step 2:
The number 49 fits into 31 0 times, leaving a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 49

Let's proceed to step 3:
315 divided by 49 is 6 with a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 294 from 315 to get 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 49

Step 4:
49 goes into 213 4 times with a remainder of 17.
The next digit of our result is 4. 
Result so far: 64.0
Subtracting 196 from 213 leaves us with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 49

Let's proceed to step 5:
49 can be fit into 170 3 times, resulting in a remainder of 23.
The next digit of our result is 3. 
Result so far: 643.0
If we take 147 away from 170, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 6:
49 goes into 230 4 times with a remainder of 34.
The next digit of our result is 4. 
Result so far: 643.4
The remainder is 34 after subtracting 196 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
If we divide 340 by 49, we get 6 and a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 643.46
Subtract 294 from 340 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 8:
49 goes into 460 9 times with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 643.469
Subtracting 441 from 460 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 9:
The number 49 fits into 190 3 times, leaving a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 643.4693
If we subtract 147 from 190, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 10:
When dividing 430 by 49, we get 8 with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 643.46938
Subtract 392 from 430 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 11:
49 can be fit into 380 7 times, resulting in a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 643.469387
Subtract 343 from 380 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 12:
370 divided by 49 is 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 643.4693877
The remainder is 27 after subtracting 343 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

In conclusion, the division gives 643.4693877 with a balance of 2.7e-07.
