87542 divided by 53 
The aim is to understand the frequency of 53 in 87542.

Going ahead to step 1:
53 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
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

Let's proceed to step 2:
53 goes into 87 1 times with a remainder of 34.
The next digit of our result is 1. 
Result so far: 1.0
If we take 53 away from 87, we end up with 34.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 53

Moving on to step 3:
When dividing 345 by 53, we get 6 with a remainder of 27.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 27 after subtracting 318 from 345.
Take the next digit (4) from the dividend and append it to 27, then repeat: 274 / 53

Moving on to step 4:
The number 53 fits into 274 5 times, leaving a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 165.0
The remainder is 9 after subtracting 265 from 274.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 53

Moving on to step 5:
The number 53 fits into 92 1 times, leaving a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 1651.0
Deduct 53 from 92 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 6:
The number 53 fits into 390 7 times, leaving a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 1651.7
Subtract 371 from 390 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
53 can be fit into 190 3 times, resulting in a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 1651.73
Deduct 159 from 190 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
The number 53 fits into 310 5 times, leaving a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 1651.735
If we take 265 away from 310, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 9:
53 can be fit into 450 8 times, resulting in a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 1651.7358
If we take 424 away from 450, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
The number 53 fits into 260 4 times, leaving a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 1651.73584
Deduct 212 from 260 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
480 divided by 53 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 1651.735849
If we subtract 477 from 480, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
53 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 1651.735849
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
300 divided by 53 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 1651.73584905
Deduct 265 from 300 and we're left 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.

The final result is 1651.73584905 with a remainder of 3.5e-08.
