We're dividing 53146387 by 427 
The aim is to understand the frequency of 427 in 53146387.

Going ahead to step 1:
427 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 427

Moving on to step 2:
The number 427 fits into 53 0 times, leaving a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 427

Step 3:
If we divide 531 by 427, we get 1 and a remainder of 104.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 427 from 531 leaves us with 104.
Fetch the next digit (4) from the dividend, attach it to 104 and continue: 1044 / 427

Advancing to step 4:
The number 427 fits into 1044 2 times, leaving a remainder of 190.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 854 from 1044 leaves us with 190.
Bring next digit (6) of the dividend behind the 190 and repeat the process: 1906 / 427

Moving on to step 5:
The number 427 fits into 1906 4 times, leaving a remainder of 198.
Write down 4 as next digit of the result. 
Result so far: 124.0
Subtracting 1708 from 1906 leaves us with 198.
Take the next digit (3) from the dividend and append it to 198, then repeat: 1983 / 427

Advancing to step 6:
427 goes into 1983 4 times with a remainder of 275.
Use 4 as the next digit of our solution. 
Result so far: 1244.0
If we subtract 1708 from 1983, we get 275.
Take the next digit (8) from the dividend and append it to 275, then repeat: 2758 / 427

Advancing to step 7:
If we divide 2758 by 427, we get 6 and a remainder of 196.
Record the quotient 6 as the next digit in the result. 
Result so far: 12446.0
Subtract 2562 from 2758 to get 196.
Take the next digit (7) from the dividend and append it to 196, then repeat: 1967 / 427

On to step 8:
427 can be fit into 1967 4 times, resulting in a remainder of 259.
Write down 4 as next digit of the result. 
Result so far: 124464.0
If we subtract 1708 from 1967, we get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

On to step 9:
The number 427 fits into 2590 6 times, leaving a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 124464.6
Subtract 2562 from 2590 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
427 goes into 280 0 times with a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 124464.6
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 11:
The number 427 fits into 2800 6 times, leaving a remainder of 238.
Record the quotient 6 as the next digit in the result. 
Result so far: 124464.606
The remainder is 238 after subtracting 2562 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 12:
If we divide 2380 by 427, we get 5 and a remainder of 245.
Record the quotient 5 as the next digit in the result. 
Result so far: 124464.6065
Deduct 2135 from 2380 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 13:
427 goes into 2450 5 times with a remainder of 315.
Put 5 as the next digit of the answer. 
Result so far: 124464.60655
If we subtract 2135 from 2450, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

The final result is 124464.60655 with a remainder of 0.000315.
