412987 divided by 53 
The aim is to understand the frequency of 53 in 412987.

Moving on to step 1:
4 divided by 53 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 53

Step 2:
41 divided by 53 is 0 with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 41 to get 41.
Bring next digit (2) of the dividend behind the 41 and repeat the process: 412 / 53

Moving on to step 3:
412 divided by 53 is 7 with a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 371 from 412 leaves us with 41.
Include the next digit (9) from the dividend after 41, then repeat: 419 / 53

Let's proceed to step 4:
When dividing 419 by 53, we get 7 with a remainder of 48.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
If we subtract 371 from 419, we get 48.
Take the next digit (8) from the dividend and append it to 48, then repeat: 488 / 53

Step 5:
When dividing 488 by 53, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 779.0
If we take 477 away from 488, we end up with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 53

Going ahead to step 6:
53 goes into 117 2 times with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 7792.0
The remainder is 11 after subtracting 106 from 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
110 divided by 53 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 7792.2
The remainder is 4 after subtracting 106 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
40 divided by 53 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 7792.2
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
400 divided by 53 is 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 7792.207
If we take 371 away from 400, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 10:
If we divide 290 by 53, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 7792.2075
The remainder is 25 after subtracting 265 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
53 can be fit into 250 4 times, resulting in a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 7792.20754
The remainder is 38 after subtracting 212 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
If we divide 380 by 53, we get 7 and a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 7792.207547
The remainder is 9 after subtracting 371 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 13:
53 goes into 90 1 times with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 7792.2075471
If we subtract 53 from 90, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 14:
53 goes into 370 6 times with a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 7792.20754716
If we subtract 318 from 370, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 7792.20754716, with a leftover of 5.2e-08.
