665893 divided by 53 
The aim is to understand the frequency of 53 in 665893.

Let's proceed to step 1:
6 divided by 53 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 53

Let's proceed to step 2:
53 goes into 66 1 times with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 53 from 66 and we're left with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 53

Going ahead to step 3:
If we divide 135 by 53, we get 2 and a remainder of 29.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 106 from 135, we get 29.
Fetch the next digit (8) from the dividend, attach it to 29 and continue: 298 / 53

Advancing to step 4:
298 divided by 53 is 5 with a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
If we subtract 265 from 298, we get 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 53

Step 5:
339 divided by 53 is 6 with a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 1256.0
Deduct 318 from 339 and we're left with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 53

Step 6:
When dividing 213 by 53, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 12564.0
Deduct 212 from 213 and we're left 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.

Going ahead to step 7:
If we divide 10 by 53, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 12564.0
Deduct 0 from 10 and we're left 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.

Going ahead to step 8:
The number 53 fits into 100 1 times, leaving a remainder of 47.
The next digit of our result is 1. 
Result so far: 12564.01
If we subtract 53 from 100, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 9:
The number 53 fits into 470 8 times, leaving a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 12564.018
The remainder is 46 after subtracting 424 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
53 goes into 460 8 times with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 12564.0188
Subtract 424 from 460 to get 36.
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 12564.0188, and the remainder is 0.00036.
