Let's divide 690209 by 53
The aim is to understand the frequency of 53 in 690209.

Advancing to step 1:
If we divide 6 by 53, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 53

Going ahead to step 2:
The number 53 fits into 69 1 times, leaving a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 16 after subtracting 53 from 69.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 53

Step 3:
If we divide 160 by 53, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 159 away from 160, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 53

Advancing to step 4:
53 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 53

Going ahead to step 5:
53 can be fit into 120 2 times, resulting in a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 1302.0
Subtract 106 from 120 to get 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 53

On to step 6:
53 goes into 149 2 times with a remainder of 43.
Write down 2 as next digit of the result. 
Result so far: 13022.0
Subtract 106 from 149 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
53 goes into 430 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 13022.8
Subtracting 424 from 430 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
53 goes into 60 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 13022.81
If we take 53 away from 60, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
When dividing 70 by 53, we get 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 13022.811
If we subtract 53 from 70, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The quotient of the division is 13022.811, and the remainder is 0.0017.
