723103 divided by 49 
The aim is to understand the frequency of 49 in 723103.

Let's proceed to step 1:
When dividing 7 by 49, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 49

Going ahead to step 2:
When dividing 72 by 49, we get 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 49 from 72 and we're left with 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 49

Advancing to step 3:
49 goes into 233 4 times with a remainder of 37.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 196 away from 233, we end up with 37.
Append the next digit (1) from the dividend to 37 and continue with: 371 / 49

Going ahead to step 4:
When dividing 371 by 49, we get 7 with a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.0
Subtract 343 from 371 to get 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 49

Going ahead to step 5:
When dividing 280 by 49, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 1475.0
If we take 245 away from 280, we end up with 35.
Append the next digit (3) from the dividend to 35 and continue with: 353 / 49

Advancing to step 6:
When dividing 353 by 49, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 14757.0
Deduct 343 from 353 and we're left 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.

Step 7:
49 can be fit into 100 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 14757.2
The remainder is 2 after subtracting 98 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead 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: 14757.2
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
The number 49 fits into 200 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 14757.204
If we subtract 196 from 200, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
If we divide 40 by 49, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 14757.204
The remainder is 40 after subtracting 0 from 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:
400 divided by 49 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 14757.20408
Subtracting 392 from 400 leaves us 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:
80 divided by 49 is 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 14757.204081
If we take 49 away from 80, we end up 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.

Going ahead to step 13:
The number 49 fits into 310 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 14757.2040816
Subtracting 294 from 310 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
160 divided by 49 is 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 14757.20408163
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 14757.20408163 and a remainder of 1.3e-08.
