We're dividing 53865643 by 468 
The aim is to understand the frequency of 468 in 53865643.

Step 1:
468 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 468

On to step 2:
The number 468 fits into 53 0 times, leaving a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Grab the next digit (8) from the dividend, add it to 53, then carry on: 538 / 468

Let's proceed to step 3:
468 goes into 538 1 times with a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 468 from 538, we get 70.
Take the next digit (6) from the dividend and append it to 70, then repeat: 706 / 468

Advancing to step 4:
468 goes into 706 1 times with a remainder of 238.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 468 from 706 leaves us with 238.
Bring next digit (5) of the dividend behind the 238 and repeat the process: 2385 / 468

Going ahead to step 5:
2385 divided by 468 is 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
Subtract 2340 from 2385 to get 45.
Fetch the next digit (6) from the dividend, attach it to 45 and continue: 456 / 468

Moving on to step 6:
468 can be fit into 456 0 times, resulting in a remainder of 456.
The next digit of our result is 0. 
Result so far: 1150.0
Subtracting 0 from 456 leaves us with 456.
Take the next digit (4) from the dividend and append it to 456, then repeat: 4564 / 468

Moving on to step 7:
468 can be fit into 4564 9 times, resulting in a remainder of 352.
The next digit of our result is 9. 
Result so far: 11509.0
Deduct 4212 from 4564 and we're left with 352.
Bring next digit (3) of the dividend behind the 352 and repeat the process: 3523 / 468

Going ahead to step 8:
468 can be fit into 3523 7 times, resulting in a remainder of 247.
The number 7 becomes the next digit in our result. 
Result so far: 115097.0
If we take 3276 away from 3523, we end up with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Moving on to step 9:
468 can be fit into 2470 5 times, resulting in a remainder of 130.
Put 5 as the next digit of the answer. 
Result so far: 115097.5
If we take 2340 away from 2470, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 10:
1300 divided by 468 is 2 with a remainder of 364.
The number 2 becomes the next digit in our result. 
Result so far: 115097.52
Deduct 936 from 1300 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Let's proceed to step 11:
468 goes into 3640 7 times with a remainder of 364.
The number 7 becomes the next digit in our result. 
Result so far: 115097.527
Deduct 3276 from 3640 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 12:
When dividing 3640 by 468, we get 7 with a remainder of 364.
The number 7 becomes the next digit in our result. 
Result so far: 115097.5277
Deduct 3276 from 3640 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

The final result is 115097.5277 with a remainder of 0.00364.
