525551 divided by 49 
The aim is to understand the frequency of 49 in 525551.

Step 1:
49 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 49

On to step 2:
When dividing 52 by 49, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 3 after subtracting 49 from 52.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 49

Going ahead to step 3:
49 can be fit into 35 0 times, resulting in a remainder of 35.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 35 and we're left with 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 49

Advancing to step 4:
The number 49 fits into 355 7 times, leaving a remainder of 12.
The next digit of our result is 7. 
Result so far: 107.0
If we take 343 away from 355, we end up with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 49

Step 5:
If we divide 125 by 49, we get 2 and a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 1072.0
Deduct 98 from 125 and we're left with 27.
Grab the next digit (1) from the dividend, add it to 27, then carry on: 271 / 49

Let's proceed to step 6:
49 goes into 271 5 times with a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 10725.0
The remainder is 26 after subtracting 245 from 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
260 divided by 49 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 10725.5
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.

Advancing to step 8:
The number 49 fits into 150 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 10725.53
Subtracting 147 from 150 leaves us 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:
49 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 10725.53
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.

Advancing to step 10:
The number 49 fits into 300 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 10725.5306
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
If we divide 60 by 49, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 10725.53061
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.

Advancing to step 12:
If we divide 110 by 49, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 10725.530612
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.

Let's proceed to step 13:
When dividing 120 by 49, we get 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 10725.5306122
Subtract 98 from 120 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

In conclusion, the division gives 10725.5306122 with a balance of 2.2e-07.
