We're dividing 670023 by 53 
The aim is to understand the frequency of 53 in 670023.

Advancing to step 1:
The number 53 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 53

Advancing to step 2:
67 divided by 53 is 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 53 from 67, we get 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 53

Step 3:
53 goes into 140 2 times with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 34 after subtracting 106 from 140.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 53

Moving on to step 4:
When dividing 340 by 53, we get 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
Subtract 318 from 340 to get 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 53

On to step 5:
The number 53 fits into 222 4 times, leaving a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 1264.0
If we take 212 away from 222, we end up with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 53

Moving on to step 6:
When dividing 103 by 53, we get 1 with a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 12641.0
Subtract 53 from 103 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 7:
53 goes into 500 9 times with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 12641.9
Deduct 477 from 500 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 8:
53 can be fit into 230 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 12641.94
If we subtract 212 from 230, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
When dividing 180 by 53, we get 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 12641.943
Subtract 159 from 180 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 10:
210 divided by 53 is 3 with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 12641.9433
If we take 159 away from 210, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Our division results in 12641.9433 with a remaining 0.00051.
