We look at the division of 351605 by 48 
The aim is to understand the frequency of 48 in 351605.

Moving on to step 1:
48 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 48

Going ahead to step 2:
48 can be fit into 35 0 times, resulting in a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 48

Advancing to step 3:
The number 48 fits into 351 7 times, leaving a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 336 away from 351, we end up with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 48

Advancing to step 4:
48 can be fit into 156 3 times, resulting in a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 73.0
Subtracting 144 from 156 leaves us with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 48

Going ahead to step 5:
48 can be fit into 120 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 732.0
Subtract 96 from 120 to get 24.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 48

Step 6:
When dividing 245 by 48, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 7325.0
Subtract 240 from 245 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
50 divided by 48 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 7325.1
If we take 48 away from 50, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
If we divide 20 by 48, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 7325.1
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
200 divided by 48 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 7325.104
If we take 192 away from 200, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
80 divided by 48 is 1 with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 7325.1041
If we subtract 48 from 80, 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.

Going ahead to step 11:
48 can be fit into 320 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 7325.10416
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
If we divide 320 by 48, we get 6 and a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 7325.104166
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 7325.104166 and a remainder of 3.2e-06.
