126661 ÷ 53 
The aim is to understand the frequency of 53 in 126661.

Let's proceed to step 1:
53 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 53

On to step 2:
When dividing 12 by 53, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 53

On to step 3:
The number 53 fits into 126 2 times, leaving a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 106 from 126 leaves us with 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 53

Moving on to step 4:
53 goes into 206 3 times with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 159 from 206, we get 47.
Bring next digit (6) of the dividend behind the 47 and repeat the process: 476 / 53

Let's proceed to step 5:
If we divide 476 by 53, we get 8 and a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 238.0
Subtracting 424 from 476 leaves us with 52.
Take the next digit (1) from the dividend and append it to 52, then repeat: 521 / 53

Going ahead to step 6:
521 divided by 53 is 9 with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 2389.0
If we take 477 away from 521, 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.

Step 7:
53 can be fit into 440 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 2389.8
If we take 424 away from 440, we end up 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.

Step 8:
53 goes into 160 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 2389.83
If we take 159 away from 160, we end up 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:
53 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 2389.83
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
100 divided by 53 is 1 with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 2389.8301
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.

Advancing to step 11:
53 can be fit into 470 8 times, resulting in a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 2389.83018
Deduct 424 from 470 and we're left 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:
When dividing 460 by 53, we get 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 2389.830188
If we subtract 424 from 460, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 2389.830188 with a remaining 3.6e-06.
