520053 divided by 49 
The aim is to understand the frequency of 49 in 520053.

Going ahead to step 1:
When dividing 5 by 49, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 49

On to step 2:
49 can be fit into 52 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 3 after subtracting 49 from 52.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 49

Step 3:
30 divided by 49 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 49

Moving on to step 4:
The number 49 fits into 300 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
If we subtract 294 from 300, we get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 49

Advancing to step 5:
65 divided by 49 is 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1061.0
Subtract 49 from 65 to get 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 49

Step 6:
49 can be fit into 163 3 times, resulting in a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 10613.0
If we subtract 147 from 163, we get 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 7:
49 goes into 160 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 10613.3
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 8:
49 can be fit into 130 2 times, resulting in a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 10613.32
Deduct 98 from 130 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
If we divide 320 by 49, we get 6 and a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 10613.326
Subtracting 294 from 320 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
The number 49 fits into 260 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 10613.3265
Subtracting 245 from 260 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
If we divide 150 by 49, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 10613.32653
Deduct 147 from 150 and we're left 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 12:
The number 49 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 10613.32653
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
When dividing 300 by 49, we get 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 10613.3265306
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.

Step 14:
49 can be fit into 60 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 10613.32653061
Subtract 49 from 60 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 10613.32653061, and the remainder is 1.1e-08.
