We're dividing 77435944 by 825 
The aim is to understand the frequency of 825 in 77435944.

Advancing to step 1:
825 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 825

Step 2:
825 can be fit into 77 0 times, resulting in a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Append the next digit (4) from the dividend to 77 and continue with: 774 / 825

Advancing to step 3:
If we divide 774 by 825, we get 0 and a remainder of 774.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 774, we get 774.
Bring next digit (3) of the dividend behind the 774 and repeat the process: 7743 / 825

Step 4:
7743 divided by 825 is 9 with a remainder of 318.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 7425 from 7743, we get 318.
Bring next digit (5) of the dividend behind the 318 and repeat the process: 3185 / 825

Let's proceed to step 5:
3185 divided by 825 is 3 with a remainder of 710.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
If we take 2475 away from 3185, we end up with 710.
Take the next digit (9) from the dividend and append it to 710, then repeat: 7109 / 825

Advancing to step 6:
When dividing 7109 by 825, we get 8 with a remainder of 509.
Use 8 as the next digit of our solution. 
Result so far: 938.0
If we subtract 6600 from 7109, we get 509.
Bring next digit (4) of the dividend behind the 509 and repeat the process: 5094 / 825

Advancing to step 7:
When dividing 5094 by 825, we get 6 with a remainder of 144.
Write down 6 as next digit of the result. 
Result so far: 9386.0
Deduct 4950 from 5094 and we're left with 144.
Take the next digit (4) from the dividend and append it to 144, then repeat: 1444 / 825

Going ahead to step 8:
When dividing 1444 by 825, we get 1 with a remainder of 619.
Write down 1 as next digit of the result. 
Result so far: 93861.0
Deduct 825 from 1444 and we're left with 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Going ahead to step 9:
When dividing 6190 by 825, we get 7 with a remainder of 415.
The number 7 becomes the next digit in our result. 
Result so far: 93861.7
If we take 5775 away from 6190, we end up with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Going ahead to step 10:
If we divide 4150 by 825, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 93861.75
Subtract 4125 from 4150 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.

Advancing to step 11:
The number 825 fits into 250 0 times, leaving a remainder of 250.
The next digit of our result is 0. 
Result so far: 93861.75
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 12:
825 can be fit into 2500 3 times, resulting in a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 93861.7503
Subtracting 2475 from 2500 leaves us 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 13:
825 goes into 250 0 times with a remainder of 250.
The next digit of our result is 0. 
Result so far: 93861.7503
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 14:
2500 divided by 825 is 3 with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 93861.750303
The remainder is 25 after subtracting 2475 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 15:
825 can be fit into 250 0 times, resulting in a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 93861.750303
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 16:
The number 825 fits into 2500 3 times, leaving a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 93861.75030303
The remainder is 25 after subtracting 2475 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 93861.75030303 and a remainder of 2.5e-08.
