We're dividing 813 by 48 
The aim is to understand the frequency of 48 in 813.

Advancing to step 1:
When dividing 8 by 48, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 48

Advancing to step 2:
If we divide 81 by 48, we get 1 and a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 33 after subtracting 48 from 81.
Bring next digit (3) of the dividend behind the 33 and repeat the process: 333 / 48

Advancing to step 3:
When dividing 333 by 48, we get 6 with a remainder of 45.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 288 away from 333, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 4:
450 divided by 48 is 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 16.9
If we subtract 432 from 450, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 5:
48 can be fit into 180 3 times, resulting in a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 16.93
If we subtract 144 from 180, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 6:
48 goes into 360 7 times with a remainder of 24.
The next digit of our result is 7. 
Result so far: 16.937
Deduct 336 from 360 and we're left 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.

Moving on to step 7:
240 divided by 48 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 16.9375
Subtract 240 from 240 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.

Going ahead to step 8:
When dividing 0 by 48, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16.9375
Deduct 0 from 0 and we're left 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.

Moving on to step 9:
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: 16.9375
If we take 0 away from 0, we end up 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.

After the division, we end up with 16.9375 and a remainder of 0.0.
