31091652 ÷ 869 
The aim is to understand the frequency of 869 in 31091652.

Going ahead to step 1:
869 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 869

Advancing to step 2:
When dividing 31 by 869, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 869

Advancing to step 3:
If we divide 310 by 869, we get 0 and a remainder of 310.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 310 after subtracting 0 from 310.
Append the next digit (9) from the dividend to 310 and continue with: 3109 / 869

Moving on to step 4:
869 goes into 3109 3 times with a remainder of 502.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 2607 from 3109 leaves us with 502.
Include the next digit (1) from the dividend after 502, then repeat: 5021 / 869

Advancing to step 5:
When dividing 5021 by 869, we get 5 with a remainder of 676.
Put 5 as the next digit of the answer. 
Result so far: 35.0
The remainder is 676 after subtracting 4345 from 5021.
Bring next digit (6) of the dividend behind the 676 and repeat the process: 6766 / 869

On to step 6:
869 goes into 6766 7 times with a remainder of 683.
Use 7 as the next digit of our solution. 
Result so far: 357.0
Deduct 6083 from 6766 and we're left with 683.
Include the next digit (5) from the dividend after 683, then repeat: 6835 / 869

Let's proceed to step 7:
869 goes into 6835 7 times with a remainder of 752.
The next digit of our result is 7. 
Result so far: 3577.0
Subtracting 6083 from 6835 leaves us with 752.
Bring next digit (2) of the dividend behind the 752 and repeat the process: 7522 / 869

Step 8:
7522 divided by 869 is 8 with a remainder of 570.
Write down 8 as next digit of the result. 
Result so far: 35778.0
Subtracting 6952 from 7522 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Moving on to step 9:
When dividing 5700 by 869, we get 6 with a remainder of 486.
The next digit of our result is 6. 
Result so far: 35778.6
If we take 5214 away from 5700, we end up with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

On to step 10:
When dividing 4860 by 869, we get 5 with a remainder of 515.
Put 5 as the next digit of the answer. 
Result so far: 35778.65
If we subtract 4345 from 4860, we get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Advancing to step 11:
869 can be fit into 5150 5 times, resulting in a remainder of 805.
The number 5 becomes the next digit in our result. 
Result so far: 35778.655
Subtract 4345 from 5150 to get 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

The final outcome is 35778.655, with a leftover of 0.0805.
