We look at the division of 770617 by 48 
The aim is to understand the frequency of 48 in 770617.

On to step 1:
48 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 48

Advancing to step 2:
48 goes into 77 1 times with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 29 after subtracting 48 from 77.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 48

Going ahead to step 3:
When dividing 290 by 48, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 288 from 290 and we're left with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 48

Let's proceed to step 4:
26 divided by 48 is 0 with a remainder of 26.
The next digit of our result is 0. 
Result so far: 160.0
Subtract 0 from 26 to get 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 48

Going ahead to step 5:
The number 48 fits into 261 5 times, leaving a remainder of 21.
The number 5 becomes the next digit in our result. 
Result so far: 1605.0
Subtract 240 from 261 to get 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 48

On to step 6:
217 divided by 48 is 4 with a remainder of 25.
The next digit of our result is 4. 
Result so far: 16054.0
Deduct 192 from 217 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
250 divided by 48 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 16054.5
If we subtract 240 from 250, we 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.

Let's proceed to step 8:
48 can be fit into 100 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 16054.52
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
The number 48 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 16054.52
Subtracting 0 from 40 leaves us 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.

Advancing to step 10:
If we divide 400 by 48, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 16054.5208
If we subtract 384 from 400, 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.

Going ahead to step 11:
48 can be fit into 160 3 times, resulting in a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 16054.52083
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.

On to step 12:
When dividing 160 by 48, we get 3 with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 16054.520833
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 result is 16054.520833 with a remainder of 1.6e-06.
