403609 divided by 53 
The aim is to understand the frequency of 53 in 403609.

Moving on to step 1:
4 divided by 53 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 53

Moving on to step 2:
53 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 53

Let's proceed to step 3:
If we divide 403 by 53, we get 7 and a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 371 from 403 and we're left with 32.
Grab the next digit (6) from the dividend, add it to 32, then carry on: 326 / 53

Step 4:
326 divided by 53 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
Subtracting 318 from 326 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 53

Let's proceed to step 5:
80 divided by 53 is 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 761.0
Deduct 53 from 80 and we're left with 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 53

Going ahead to step 6:
53 can be fit into 279 5 times, resulting in a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 7615.0
If we take 265 away from 279, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
140 divided by 53 is 2 with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 7615.2
If we subtract 106 from 140, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
When dividing 340 by 53, we get 6 with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 7615.26
If we take 318 away from 340, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
220 divided by 53 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 7615.264
Deduct 212 from 220 and we're left 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.

Moving on to step 10:
53 goes into 80 1 times with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 7615.2641
The remainder is 27 after subtracting 53 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 11:
53 goes into 270 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 7615.26415
The remainder is 5 after subtracting 265 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
53 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 7615.26415
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
When dividing 500 by 53, we get 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 7615.2641509
Deduct 477 from 500 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 14:
If we divide 230 by 53, we get 4 and a remainder of 18.
The next digit of our result is 4. 
Result so far: 7615.26415094
Subtract 212 from 230 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 7615.26415094 and a remainder of 1.8e-08.
