We're dividing 1648235 by 772 
The aim is to understand the frequency of 772 in 1648235.

On to step 1:
If we divide 1 by 772, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 772

Moving on to step 2:
772 goes into 16 0 times with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 772

Let's proceed to step 3:
772 can be fit into 164 0 times, resulting in a remainder of 164.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 164 after subtracting 0 from 164.
Grab the next digit (8) from the dividend, add it to 164, then carry on: 1648 / 772

Going ahead to step 4:
If we divide 1648 by 772, we get 2 and a remainder of 104.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1544 from 1648 and we're left with 104.
Grab the next digit (2) from the dividend, add it to 104, then carry on: 1042 / 772

Step 5:
772 goes into 1042 1 times with a remainder of 270.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 772 from 1042 and we're left with 270.
Include the next digit (3) from the dividend after 270, then repeat: 2703 / 772

Advancing to step 6:
772 goes into 2703 3 times with a remainder of 387.
Write down 3 as next digit of the result. 
Result so far: 213.0
The remainder is 387 after subtracting 2316 from 2703.
Append the next digit (5) from the dividend to 387 and continue with: 3875 / 772

Moving on to step 7:
The number 772 fits into 3875 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 2135.0
If we take 3860 away from 3875, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
The number 772 fits into 150 0 times, leaving a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 2135.0
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 9:
When dividing 1500 by 772, we get 1 with a remainder of 728.
Write down 1 as next digit of the result. 
Result so far: 2135.01
Deduct 772 from 1500 and we're left with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Advancing to step 10:
The number 772 fits into 7280 9 times, leaving a remainder of 332.
Use 9 as the next digit of our solution. 
Result so far: 2135.019
Subtracting 6948 from 7280 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 11:
772 goes into 3320 4 times with a remainder of 232.
The number 4 becomes the next digit in our result. 
Result so far: 2135.0194
Deduct 3088 from 3320 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 12:
2320 divided by 772 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 2135.01943
Subtract 2316 from 2320 to 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.

Moving on to step 13:
When dividing 40 by 772, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 2135.01943
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.

Advancing to step 14:
772 can be fit into 400 0 times, resulting in a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 2135.01943
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 2135.01943 and a remainder of 4e-06.
