Let's divide 51902734 by 825
The aim is to understand the frequency of 825 in 51902734.

Moving on to step 1:
When dividing 5 by 825, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 825

Moving on to step 2:
When dividing 51 by 825, we get 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 825

Moving on to step 3:
825 goes into 519 0 times with a remainder of 519.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 519, we get 519.
Grab the next digit (0) from the dividend, add it to 519, then carry on: 5190 / 825

Advancing to step 4:
825 goes into 5190 6 times with a remainder of 240.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 4950 from 5190 to get 240.
Fetch the next digit (2) from the dividend, attach it to 240 and continue: 2402 / 825

Going ahead to step 5:
825 goes into 2402 2 times with a remainder of 752.
Put 2 as the next digit of the answer. 
Result so far: 62.0
The remainder is 752 after subtracting 1650 from 2402.
Append the next digit (7) from the dividend to 752 and continue with: 7527 / 825

Let's proceed to step 6:
When dividing 7527 by 825, we get 9 with a remainder of 102.
Use 9 as the next digit of our solution. 
Result so far: 629.0
The remainder is 102 after subtracting 7425 from 7527.
Include the next digit (3) from the dividend after 102, then repeat: 1023 / 825

Let's proceed to step 7:
If we divide 1023 by 825, we get 1 and a remainder of 198.
The number 1 becomes the next digit in our result. 
Result so far: 6291.0
Subtract 825 from 1023 to get 198.
Take the next digit (4) from the dividend and append it to 198, then repeat: 1984 / 825

Going ahead to step 8:
825 goes into 1984 2 times with a remainder of 334.
Put 2 as the next digit of the answer. 
Result so far: 62912.0
Deduct 1650 from 1984 and we're left with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Let's proceed to step 9:
825 can be fit into 3340 4 times, resulting in a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 62912.4
If we subtract 3300 from 3340, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
825 goes into 400 0 times with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 62912.4
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 11:
825 can be fit into 4000 4 times, resulting in a remainder of 700.
Use 4 as the next digit of our solution. 
Result so far: 62912.404
If we subtract 3300 from 4000, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 12:
825 can be fit into 7000 8 times, resulting in a remainder of 400.
Use 8 as the next digit of our solution. 
Result so far: 62912.4048
Subtracting 6600 from 7000 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 13:
If we divide 4000 by 825, we get 4 and a remainder of 700.
The number 4 becomes the next digit in our result. 
Result so far: 62912.40484
Subtract 3300 from 4000 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 14:
825 can be fit into 7000 8 times, resulting in a remainder of 400.
Use 8 as the next digit of our solution. 
Result so far: 62912.404848
Deduct 6600 from 7000 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 15:
4000 divided by 825 is 4 with a remainder of 700.
The next digit of our result is 4. 
Result so far: 62912.4048484
The remainder is 700 after subtracting 3300 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 16:
825 goes into 7000 8 times with a remainder of 400.
The next digit of our result is 8. 
Result so far: 62912.40484848
If we subtract 6600 from 7000, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Our division results in 62912.40484848 with a remaining 4e-07.
