We divide 143468 by 53
The aim is to understand the frequency of 53 in 143468.

Step 1:
53 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 53

Going ahead to step 2:
53 can be fit into 14 0 times, resulting in a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 53

On to step 3:
The number 53 fits into 143 2 times, leaving a remainder of 37.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 106 away from 143, we end up with 37.
Fetch the next digit (4) from the dividend, attach it to 37 and continue: 374 / 53

Advancing to step 4:
53 can be fit into 374 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 27.0
The remainder is 3 after subtracting 371 from 374.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 53

On to step 5:
The number 53 fits into 36 0 times, leaving a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 270.0
If we subtract 0 from 36, we get 36.
Include the next digit (8) from the dividend after 36, then repeat: 368 / 53

Let's proceed to step 6:
If we divide 368 by 53, we get 6 and a remainder of 50.
The next digit of our result is 6. 
Result so far: 2706.0
If we take 318 away from 368, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
53 can be fit into 500 9 times, resulting in a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 2706.9
If we take 477 away from 500, we end up 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.

Going ahead to step 8:
The number 53 fits into 230 4 times, leaving a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 2706.94
If we take 212 away from 230, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
180 divided by 53 is 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 2706.943
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.

Step 10:
The number 53 fits into 210 3 times, leaving a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 2706.9433
The remainder is 51 after subtracting 159 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final result is 2706.9433 with a remainder of 0.00051.
