We divide 625908 by 53
The aim is to understand the frequency of 53 in 625908.

On to step 1:
If we divide 6 by 53, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 53

Moving on to step 2:
62 divided by 53 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 53 from 62 and we're left with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 53

Moving on to step 3:
53 goes into 95 1 times with a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 53 from 95 leaves us with 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 53

On to step 4:
If we divide 429 by 53, we get 8 and a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
Subtracting 424 from 429 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 53

On to step 5:
If we divide 50 by 53, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 1180.0
Subtract 0 from 50 to get 50.
Take the next digit (8) from the dividend and append it to 50, then repeat: 508 / 53

On to step 6:
508 divided by 53 is 9 with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 11809.0
Deduct 477 from 508 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
When dividing 310 by 53, we get 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 11809.5
Subtracting 265 from 310 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 8:
If we divide 450 by 53, we get 8 and a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 11809.58
Subtract 424 from 450 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
If we divide 260 by 53, we get 4 and a remainder of 48.
The next digit of our result is 4. 
Result so far: 11809.584
If we subtract 212 from 260, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
The number 53 fits into 480 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 11809.5849
If we subtract 477 from 480, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
53 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 11809.5849
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
300 divided by 53 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 11809.584905
If we subtract 265 from 300, we 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.

Advancing to step 13:
If we divide 350 by 53, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 11809.5849056
The remainder is 32 after subtracting 318 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
53 goes into 320 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 11809.58490566
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.

The final outcome is 11809.58490566, with a leftover of 2e-09.
