607212 ÷ 53 
The aim is to understand the frequency of 53 in 607212.

On 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.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 53

Let's proceed to step 2:
60 divided by 53 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 53 from 60 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 53

On to step 3:
53 goes into 77 1 times with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 53 from 77 to get 24.
Grab the next digit (2) from the dividend, add it to 24, then carry on: 242 / 53

Let's proceed to step 4:
242 divided by 53 is 4 with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 114.0
The remainder is 30 after subtracting 212 from 242.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 53

Advancing to step 5:
53 can be fit into 301 5 times, resulting in a remainder of 36.
Record the quotient 5 as the next digit in the result. 
Result so far: 1145.0
The remainder is 36 after subtracting 265 from 301.
Bring next digit (2) of the dividend behind the 36 and repeat the process: 362 / 53

Step 6:
53 goes into 362 6 times with a remainder of 44.
The next digit of our result is 6. 
Result so far: 11456.0
If we take 318 away from 362, we end up 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.

Moving on to step 7:
When dividing 440 by 53, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 11456.8
Subtracting 424 from 440 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
The number 53 fits into 160 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 11456.83
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.

Moving on to step 9:
The number 53 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 11456.83
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.

On to step 10:
If we divide 100 by 53, we get 1 and a remainder of 47.
The next digit of our result is 1. 
Result so far: 11456.8301
Subtracting 53 from 100 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 11:
The number 53 fits into 470 8 times, leaving a remainder of 46.
The next digit of our result is 8. 
Result so far: 11456.83018
Subtracting 424 from 470 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
460 divided by 53 is 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 11456.830188
Subtracting 424 from 460 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 11456.830188 and a remainder of 3.6e-06.
