We're dividing 615311 by 48 
The aim is to understand the frequency of 48 in 615311.

Let's proceed to step 1:
The number 48 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 48

On to step 2:
The number 48 fits into 61 1 times, leaving a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 48 from 61 and we're left with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 48

Advancing to step 3:
The number 48 fits into 135 2 times, leaving a remainder of 39.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 96 from 135 leaves us with 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 48

Step 4:
When dividing 393 by 48, we get 8 with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
Deduct 384 from 393 and we're left with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 48

Going ahead to step 5:
The number 48 fits into 91 1 times, leaving a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 1281.0
If we take 48 away from 91, we end up with 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 48

Let's proceed to step 6:
The number 48 fits into 431 8 times, leaving a remainder of 47.
Use 8 as the next digit of our solution. 
Result so far: 12818.0
Subtract 384 from 431 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 7:
When dividing 470 by 48, we get 9 with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 12818.9
Subtracting 432 from 470 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
48 goes into 380 7 times with a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 12818.97
If we take 336 away from 380, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
When dividing 440 by 48, we get 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 12818.979
Subtract 432 from 440 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
When dividing 80 by 48, we get 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 12818.9791
Subtract 48 from 80 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
If we divide 320 by 48, we get 6 and a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 12818.97916
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
48 can be fit into 320 6 times, resulting in a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 12818.979166
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 12818.979166 with a remainder of 3.2e-06.
