We look at the division of 8737 by 48 
The aim is to understand the frequency of 48 in 8737.

Moving on to step 1:
When dividing 8 by 48, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 48

Step 2:
When dividing 87 by 48, we get 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 48 away from 87, we end up with 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 48

Advancing to step 3:
The number 48 fits into 393 8 times, leaving a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 384 away from 393, we end up with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 48

Let's proceed to step 4:
When dividing 97 by 48, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 182.0
Deduct 96 from 97 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 5:
48 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 182.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 6:
If we divide 100 by 48, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 182.02
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
When dividing 40 by 48, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 182.02
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
The number 48 fits into 400 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 182.0208
If we take 384 away from 400, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
If we divide 160 by 48, we get 3 and a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 182.02083
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
The number 48 fits into 160 3 times, leaving a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 182.020833
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 182.020833, with a leftover of 1.6e-06.
