We look at the division of 507351 by 48 
The aim is to understand the frequency of 48 in 507351.

Let's proceed to step 1:
When dividing 5 by 48, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 48

Let's proceed to step 2:
48 goes into 50 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
If we take 48 away from 50, we end up with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 48

Step 3:
The number 48 fits into 27 0 times, leaving a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 27 leaves us with 27.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 48

Going ahead to step 4:
48 can be fit into 273 5 times, resulting in a remainder of 33.
Use 5 as the next digit of our solution. 
Result so far: 105.0
If we take 240 away from 273, we end up with 33.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 48

Advancing to step 5:
335 divided by 48 is 6 with a remainder of 47.
Use 6 as the next digit of our solution. 
Result so far: 1056.0
If we take 288 away from 335, we end up with 47.
Append the next digit (1) from the dividend to 47 and continue with: 471 / 48

On to step 6:
If we divide 471 by 48, we get 9 and a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 10569.0
If we take 432 away from 471, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
The number 48 fits into 390 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 10569.8
If we take 384 away from 390, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
When dividing 60 by 48, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 10569.81
If we subtract 48 from 60, we get 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 9:
48 can be fit into 120 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 10569.812
If we take 96 away from 120, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
When dividing 240 by 48, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10569.8125
Subtracting 240 from 240 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
The number 48 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10569.8125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
48 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10569.8125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 10569.8125 with a remainder of 0.0.
