We're dividing 40646 by 53 
The aim is to understand the frequency of 53 in 40646.

Going ahead to step 1:
The number 53 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 53

Advancing to step 2:
If we divide 40 by 53, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 53

On to step 3:
When dividing 406 by 53, we get 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 371 from 406 leaves us with 35.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 53

Moving on to step 4:
354 divided by 53 is 6 with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
If we take 318 away from 354, we end up with 36.
Fetch the next digit (6) from the dividend, attach it to 36 and continue: 366 / 53

Advancing to step 5:
366 divided by 53 is 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 766.0
The remainder is 48 after subtracting 318 from 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 6:
53 can be fit into 480 9 times, resulting in a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 766.9
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.

On to step 7:
When dividing 30 by 53, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 766.9
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.

Moving on to step 8:
If we divide 300 by 53, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 766.905
Subtract 265 from 300 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
When dividing 350 by 53, we get 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 766.9056
Subtract 318 from 350 to 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.

Step 10:
The number 53 fits into 320 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 766.90566
The remainder is 2 after subtracting 318 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 766.90566 and a remainder of 2e-06.
