251445 ÷ 49 
The aim is to understand the frequency of 49 in 251445.

Step 1:
49 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 49

Going ahead to step 2:
If we divide 25 by 49, we get 0 and a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 49

On to step 3:
49 can be fit into 251 5 times, resulting in a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 6 after subtracting 245 from 251.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 49

Moving on to step 4:
If we divide 64 by 49, we get 1 and a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
If we take 49 away from 64, we end up with 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 49

Step 5:
When dividing 154 by 49, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 513.0
Subtract 147 from 154 to get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 49

Moving on to step 6:
49 can be fit into 75 1 times, resulting in a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 5131.0
The remainder is 26 after subtracting 49 from 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
49 can be fit into 260 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 5131.5
If we subtract 245 from 260, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
49 can be fit into 150 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 5131.53
If we take 147 away from 150, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
The number 49 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 5131.53
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
If we divide 300 by 49, we get 6 and a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 5131.5306
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
If we divide 60 by 49, we get 1 and a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 5131.53061
Deduct 49 from 60 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
49 goes into 110 2 times with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 5131.530612
Deduct 98 from 110 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
49 goes into 120 2 times with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 5131.5306122
The remainder is 22 after subtracting 98 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 5131.5306122 and a remainder of 2.2e-07.
