550961 divided by 53 
The aim is to understand the frequency of 53 in 550961.

On to step 1:
53 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 53

Moving on to step 2:
When dividing 55 by 53, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 53 from 55 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 53

Advancing to step 3:
When dividing 20 by 53, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 20 after subtracting 0 from 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 53

Step 4:
53 goes into 209 3 times with a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
Deduct 159 from 209 and we're left with 50.
Bring next digit (6) of the dividend behind the 50 and repeat the process: 506 / 53

Advancing to step 5:
If we divide 506 by 53, we get 9 and a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 1039.0
The remainder is 29 after subtracting 477 from 506.
Include the next digit (1) from the dividend after 29, then repeat: 291 / 53

Going ahead to step 6:
When dividing 291 by 53, we get 5 with a remainder of 26.
Record the quotient 5 as the next digit in the result. 
Result so far: 10395.0
Subtract 265 from 291 to get 26.
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:
The number 53 fits into 260 4 times, leaving a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 10395.4
Subtracting 212 from 260 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 8:
53 can be fit into 480 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 10395.49
Deduct 477 from 480 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.

Step 9:
53 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 10395.49
If we subtract 0 from 30, we 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.

Step 10:
300 divided by 53 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 10395.4905
If we take 265 away from 300, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 11:
When dividing 350 by 53, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 10395.49056
If we subtract 318 from 350, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
53 can be fit into 320 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 10395.490566
Subtract 318 from 320 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 10395.490566 with a remaining 2e-07.
