We look at the division of 48201635 by 771 
The aim is to understand the frequency of 771 in 48201635.

Moving on to step 1:
771 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 771

Going ahead to step 2:
When dividing 48 by 771, we get 0 with a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Include the next digit (2) from the dividend after 48, then repeat: 482 / 771

On to step 3:
The number 771 fits into 482 0 times, leaving a remainder of 482.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 482 and we're left with 482.
Grab the next digit (0) from the dividend, add it to 482, then carry on: 4820 / 771

Moving on to step 4:
If we divide 4820 by 771, we get 6 and a remainder of 194.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 4626 from 4820, we get 194.
Bring next digit (1) of the dividend behind the 194 and repeat the process: 1941 / 771

Going ahead to step 5:
771 can be fit into 1941 2 times, resulting in a remainder of 399.
Write down 2 as next digit of the result. 
Result so far: 62.0
Deduct 1542 from 1941 and we're left with 399.
Append the next digit (6) from the dividend to 399 and continue with: 3996 / 771

On to step 6:
771 goes into 3996 5 times with a remainder of 141.
Put 5 as the next digit of the answer. 
Result so far: 625.0
Deduct 3855 from 3996 and we're left with 141.
Take the next digit (3) from the dividend and append it to 141, then repeat: 1413 / 771

Step 7:
771 goes into 1413 1 times with a remainder of 642.
Write down 1 as next digit of the result. 
Result so far: 6251.0
If we subtract 771 from 1413, we get 642.
Take the next digit (5) from the dividend and append it to 642, then repeat: 6425 / 771

Advancing to step 8:
If we divide 6425 by 771, we get 8 and a remainder of 257.
The next digit of our result is 8. 
Result so far: 62518.0
Subtract 6168 from 6425 to get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Going ahead to step 9:
771 can be fit into 2570 3 times, resulting in a remainder of 257.
Put 3 as the next digit of the answer. 
Result so far: 62518.3
The remainder is 257 after subtracting 2313 from 2570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Let's proceed to step 10:
771 goes into 2570 3 times with a remainder of 257.
Put 3 as the next digit of the answer. 
Result so far: 62518.33
If we take 2313 away from 2570, we end up with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

The quotient of the division is 62518.33, and the remainder is 0.257.
