87747148 divided by 53 
The aim is to understand the frequency of 53 in 87747148.

Going ahead to step 1:
8 divided by 53 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 53

Going ahead to step 2:
53 can be fit into 87 1 times, resulting in a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 53 from 87 leaves us with 34.
Take the next digit (7) from the dividend and append it to 34, then repeat: 347 / 53

Going ahead to step 3:
347 divided by 53 is 6 with a remainder of 29.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 318 from 347 and we're left with 29.
Fetch the next digit (4) from the dividend, attach it to 29 and continue: 294 / 53

Advancing to step 4:
53 can be fit into 294 5 times, resulting in a remainder of 29.
Write down 5 as next digit of the result. 
Result so far: 165.0
Subtract 265 from 294 to get 29.
Bring next digit (7) of the dividend behind the 29 and repeat the process: 297 / 53

Moving on to step 5:
The number 53 fits into 297 5 times, leaving a remainder of 32.
Record the quotient 5 as the next digit in the result. 
Result so far: 1655.0
If we subtract 265 from 297, we get 32.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 53

On to step 6:
53 goes into 321 6 times with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 16556.0
If we take 318 away from 321, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 53

On to step 7:
53 can be fit into 34 0 times, resulting in a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 165560.0
If we take 0 away from 34, we end up with 34.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 53

Let's proceed to step 8:
When dividing 348 by 53, we get 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 1655606.0
Subtracting 318 from 348 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
53 can be fit into 300 5 times, resulting in a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 1655606.5
Subtracting 265 from 300 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
When dividing 350 by 53, we get 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 1655606.56
If we take 318 away from 350, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
When dividing 320 by 53, we get 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 1655606.566
The remainder is 2 after subtracting 318 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 1655606.566 with a remaining 0.0002.
