Let's divide 7778973 by 175
The aim is to understand the frequency of 175 in 7778973.

On to step 1:
If we divide 7 by 175, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 175

Step 2:
If we divide 77 by 175, we get 0 and a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 175

Advancing to step 3:
175 goes into 777 4 times with a remainder of 77.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 700 away from 777, we end up with 77.
Grab the next digit (8) from the dividend, add it to 77, then carry on: 778 / 175

Going ahead to step 4:
The number 175 fits into 778 4 times, leaving a remainder of 78.
The next digit of our result is 4. 
Result so far: 44.0
The remainder is 78 after subtracting 700 from 778.
Bring next digit (9) of the dividend behind the 78 and repeat the process: 789 / 175

Advancing to step 5:
175 can be fit into 789 4 times, resulting in a remainder of 89.
Use 4 as the next digit of our solution. 
Result so far: 444.0
Subtracting 700 from 789 leaves us with 89.
Fetch the next digit (7) from the dividend, attach it to 89 and continue: 897 / 175

Step 6:
If we divide 897 by 175, we get 5 and a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 4445.0
Subtract 875 from 897 to get 22.
Grab the next digit (3) from the dividend, add it to 22, then carry on: 223 / 175

Advancing to step 7:
223 divided by 175 is 1 with a remainder of 48.
Use 1 as the next digit of our solution. 
Result so far: 44451.0
Subtract 175 from 223 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 8:
175 goes into 480 2 times with a remainder of 130.
Write down 2 as next digit of the result. 
Result so far: 44451.2
The remainder is 130 after subtracting 350 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 9:
175 goes into 1300 7 times with a remainder of 75.
The next digit of our result is 7. 
Result so far: 44451.27
If we subtract 1225 from 1300, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 10:
750 divided by 175 is 4 with a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 44451.274
If we subtract 700 from 750, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
If we divide 500 by 175, we get 2 and a remainder of 150.
The number 2 becomes the next digit in our result. 
Result so far: 44451.2742
Deduct 350 from 500 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 12:
If we divide 1500 by 175, we get 8 and a remainder of 100.
The next digit of our result is 8. 
Result so far: 44451.27428
Subtracting 1400 from 1500 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 13:
175 can be fit into 1000 5 times, resulting in a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 44451.274285
If we take 875 away from 1000, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 14:
175 goes into 1250 7 times with a remainder of 25.
The next digit of our result is 7. 
Result so far: 44451.2742857
Subtract 1225 from 1250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 15:
175 can be fit into 250 1 times, resulting in a remainder of 75.
Put 1 as the next digit of the answer. 
Result so far: 44451.27428571
Subtracting 175 from 250 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

After the division, we end up with 44451.27428571 and a remainder of 7.5e-08.
