We're dividing 25688645 by 773 
The aim is to understand the frequency of 773 in 25688645.

Moving on to step 1:
773 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 773

Moving on to step 2:
25 divided by 773 is 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Fetch the next digit (6) from the dividend, attach it to 25 and continue: 256 / 773

Going ahead to step 3:
256 divided by 773 is 0 with a remainder of 256.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 256 and we're left with 256.
Bring next digit (8) of the dividend behind the 256 and repeat the process: 2568 / 773

Advancing to step 4:
If we divide 2568 by 773, we get 3 and a remainder of 249.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 2319 from 2568 and we're left with 249.
Bring next digit (8) of the dividend behind the 249 and repeat the process: 2498 / 773

Advancing to step 5:
When dividing 2498 by 773, we get 3 with a remainder of 179.
The next digit of our result is 3. 
Result so far: 33.0
If we subtract 2319 from 2498, we get 179.
Bring next digit (6) of the dividend behind the 179 and repeat the process: 1796 / 773

Moving on to step 6:
If we divide 1796 by 773, we get 2 and a remainder of 250.
Put 2 as the next digit of the answer. 
Result so far: 332.0
Deduct 1546 from 1796 and we're left with 250.
Fetch the next digit (4) from the dividend, attach it to 250 and continue: 2504 / 773

Moving on to step 7:
The number 773 fits into 2504 3 times, leaving a remainder of 185.
The number 3 becomes the next digit in our result. 
Result so far: 3323.0
Subtracting 2319 from 2504 leaves us with 185.
Grab the next digit (5) from the dividend, add it to 185, then carry on: 1855 / 773

Advancing to step 8:
When dividing 1855 by 773, we get 2 with a remainder of 309.
The next digit of our result is 2. 
Result so far: 33232.0
Subtracting 1546 from 1855 leaves us with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Step 9:
The number 773 fits into 3090 3 times, leaving a remainder of 771.
Record the quotient 3 as the next digit in the result. 
Result so far: 33232.3
Subtracting 2319 from 3090 leaves us with 771.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7710, and continue the process.

Step 10:
7710 divided by 773 is 9 with a remainder of 753.
Record the quotient 9 as the next digit in the result. 
Result so far: 33232.39
Subtract 6957 from 7710 to get 753.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7530, and continue the process.

Going ahead to step 11:
The number 773 fits into 7530 9 times, leaving a remainder of 573.
Use 9 as the next digit of our solution. 
Result so far: 33232.399
Subtracting 6957 from 7530 leaves us with 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

The quotient of the division is 33232.399, and the remainder is 0.0573.
