We're dividing 61836415 by 53 
The aim is to understand the frequency of 53 in 61836415.

Going ahead to step 1:
If we divide 6 by 53, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 53

On to step 2:
61 divided by 53 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 8 after subtracting 53 from 61.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 53

On to step 3:
53 goes into 88 1 times with a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 53 from 88 to get 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 53

Let's proceed to step 4:
353 divided by 53 is 6 with a remainder of 35.
The next digit of our result is 6. 
Result so far: 116.0
If we take 318 away from 353, we end up with 35.
Append the next digit (6) from the dividend to 35 and continue with: 356 / 53

Going ahead to step 5:
If we divide 356 by 53, we get 6 and a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 1166.0
Subtracting 318 from 356 leaves us with 38.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 53

Step 6:
The number 53 fits into 384 7 times, leaving a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 11667.0
If we subtract 371 from 384, we get 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 53

Let's proceed to step 7:
53 goes into 131 2 times with a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 116672.0
If we subtract 106 from 131, we get 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 53

Moving on to step 8:
255 divided by 53 is 4 with a remainder of 43.
Put 4 as the next digit of the answer. 
Result so far: 1166724.0
The remainder is 43 after subtracting 212 from 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 9:
When dividing 430 by 53, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 1166724.8
If we subtract 424 from 430, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
60 divided by 53 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1166724.81
Deduct 53 from 60 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 11:
The number 53 fits into 70 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1166724.811
Subtract 53 from 70 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

In conclusion, the division gives 1166724.811 with a balance of 0.0017.
