We look at the division of 980639 by 48 
The aim is to understand the frequency of 48 in 980639.

Going ahead to step 1:
If we divide 9 by 48, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 48

Advancing to step 2:
If we divide 98 by 48, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 96 from 98, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 48

Going ahead to step 3:
When dividing 20 by 48, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 20.0
The remainder is 20 after subtracting 0 from 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 48

Going ahead to step 4:
If we divide 206 by 48, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 204.0
The remainder is 14 after subtracting 192 from 206.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 48

Moving on to step 5:
When dividing 143 by 48, we get 2 with a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 2042.0
Subtract 96 from 143 to get 47.
Fetch the next digit (9) from the dividend, attach it to 47 and continue: 479 / 48

Moving on to step 6:
When dividing 479 by 48, we get 9 with a remainder of 47.
The next digit of our result is 9. 
Result so far: 20429.0
If we subtract 432 from 479, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
48 can be fit into 470 9 times, resulting in a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 20429.9
If we take 432 away from 470, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
380 divided by 48 is 7 with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 20429.97
Subtract 336 from 380 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
When dividing 440 by 48, we get 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 20429.979
The remainder is 8 after subtracting 432 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
48 can be fit into 80 1 times, resulting in a remainder of 32.
The next digit of our result is 1. 
Result so far: 20429.9791
Deduct 48 from 80 and we're left 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.

Step 11:
The number 48 fits into 320 6 times, leaving a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 20429.97916
Subtract 288 from 320 to 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 12:
48 goes into 320 6 times with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 20429.979166
If we subtract 288 from 320, 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.

The final outcome is 20429.979166, with a leftover of 3.2e-06.
