450515 divided by 53 
The aim is to understand the frequency of 53 in 450515.

On to step 1:
When dividing 4 by 53, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 53

On to step 2:
When dividing 45 by 53, we get 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Bring next digit (0) of the dividend behind the 45 and repeat the process: 450 / 53

On to step 3:
When dividing 450 by 53, we get 8 with a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 424 from 450 and we're left with 26.
Append the next digit (5) from the dividend to 26 and continue with: 265 / 53

Going ahead to step 4:
When dividing 265 by 53, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 85.0
The remainder is 0 after subtracting 265 from 265.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 53

Step 5:
1 divided by 53 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 850.0
If we take 0 away from 1, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 53

Advancing to step 6:
15 divided by 53 is 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 8500.0
Subtracting 0 from 15 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.

Let's proceed to step 7:
The number 53 fits into 150 2 times, leaving a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 8500.2
Subtracting 106 from 150 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
440 divided by 53 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 8500.28
Subtract 424 from 440 to 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.

Going ahead to step 9:
The number 53 fits into 160 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 8500.283
Subtracting 159 from 160 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
The number 53 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 8500.283
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
The number 53 fits into 100 1 times, leaving a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 8500.28301
The remainder is 47 after subtracting 53 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 12:
If we divide 470 by 53, we get 8 and a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 8500.283018
If we subtract 424 from 470, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 13:
460 divided by 53 is 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 8500.2830188
The remainder is 36 after subtracting 424 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The quotient of the division is 8500.2830188, and the remainder is 3.6e-07.
