We're dividing 63937325 by 53 
The aim is to understand the frequency of 53 in 63937325.

On to step 1:
53 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 53

Let's proceed to step 2:
If we divide 63 by 53, we get 1 and a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 53 from 63 and we're left with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 53

Step 3:
If we divide 109 by 53, we get 2 and a remainder of 3.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 106 from 109 and we're left with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 53

Step 4:
53 goes into 33 0 times with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
If we subtract 0 from 33, we get 33.
Append the next digit (7) from the dividend to 33 and continue with: 337 / 53

Going ahead to step 5:
53 can be fit into 337 6 times, resulting in a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 1206.0
Subtracting 318 from 337 leaves us with 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 53

On to step 6:
The number 53 fits into 193 3 times, leaving a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 12063.0
Subtract 159 from 193 to get 34.
Include the next digit (2) from the dividend after 34, then repeat: 342 / 53

Step 7:
When dividing 342 by 53, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 120636.0
The remainder is 24 after subtracting 318 from 342.
Fetch the next digit (5) from the dividend, attach it to 24 and continue: 245 / 53

Going ahead to step 8:
If we divide 245 by 53, we get 4 and a remainder of 33.
The next digit of our result is 4. 
Result so far: 1206364.0
Subtract 212 from 245 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
53 goes into 330 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 1206364.6
Deduct 318 from 330 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
53 can be fit into 120 2 times, resulting in a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 1206364.62
If we subtract 106 from 120, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
If we divide 140 by 53, we get 2 and a remainder of 34.
The next digit of our result is 2. 
Result so far: 1206364.622
Subtracting 106 from 140 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 1206364.622 with a balance of 0.0034.
