Let's divide 901660 by 48
The aim is to understand the frequency of 48 in 901660.

Moving on to step 1:
48 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 48

Going ahead to step 2:
The number 48 fits into 90 1 times, leaving a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 48 away from 90, we end up with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 48

On to step 3:
If we divide 421 by 48, we get 8 and a remainder of 37.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 37 after subtracting 384 from 421.
Include the next digit (6) from the dividend after 37, then repeat: 376 / 48

Moving on to step 4:
If we divide 376 by 48, we get 7 and a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 187.0
If we take 336 away from 376, we end up with 40.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 48

On to step 5:
406 divided by 48 is 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 1878.0
Deduct 384 from 406 and we're left with 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 48

Let's proceed to step 6:
The number 48 fits into 220 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 18784.0
If we take 192 away from 220, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 7:
280 divided by 48 is 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 18784.5
Deduct 240 from 280 and we're left 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.

Going ahead to step 8:
The number 48 fits into 400 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 18784.58
Deduct 384 from 400 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 9:
The number 48 fits into 160 3 times, leaving a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 18784.583
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.

On to step 10:
48 goes into 160 3 times with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 18784.5833
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 18784.5833 and a remainder of 0.00016.
