We look at the division of 35852848 by 869 
The aim is to understand the frequency of 869 in 35852848.

Let's proceed to step 1:
When dividing 3 by 869, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 869

Advancing to step 2:
869 can be fit into 35 0 times, resulting in a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Fetch the next digit (8) from the dividend, attach it to 35 and continue: 358 / 869

Going ahead to step 3:
If we divide 358 by 869, we get 0 and a remainder of 358.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 358 leaves us with 358.
Append the next digit (5) from the dividend to 358 and continue with: 3585 / 869

Step 4:
869 goes into 3585 4 times with a remainder of 109.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 3476 from 3585, we get 109.
Bring next digit (2) of the dividend behind the 109 and repeat the process: 1092 / 869

Step 5:
869 can be fit into 1092 1 times, resulting in a remainder of 223.
Write down 1 as next digit of the result. 
Result so far: 41.0
If we take 869 away from 1092, we end up with 223.
Append the next digit (8) from the dividend to 223 and continue with: 2238 / 869

Let's proceed to step 6:
The number 869 fits into 2238 2 times, leaving a remainder of 500.
Use 2 as the next digit of our solution. 
Result so far: 412.0
Subtracting 1738 from 2238 leaves us with 500.
Take the next digit (4) from the dividend and append it to 500, then repeat: 5004 / 869

Going ahead to step 7:
The number 869 fits into 5004 5 times, leaving a remainder of 659.
Use 5 as the next digit of our solution. 
Result so far: 4125.0
If we subtract 4345 from 5004, we get 659.
Fetch the next digit (8) from the dividend, attach it to 659 and continue: 6598 / 869

Let's proceed to step 8:
When dividing 6598 by 869, we get 7 with a remainder of 515.
Put 7 as the next digit of the answer. 
Result so far: 41257.0
If we take 6083 away from 6598, we end up with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Moving on to step 9:
869 can be fit into 5150 5 times, resulting in a remainder of 805.
Put 5 as the next digit of the answer. 
Result so far: 41257.5
The remainder is 805 after subtracting 4345 from 5150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

Step 10:
If we divide 8050 by 869, we get 9 and a remainder of 229.
Use 9 as the next digit of our solution. 
Result so far: 41257.59
If we subtract 7821 from 8050, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

On to step 11:
If we divide 2290 by 869, we get 2 and a remainder of 552.
Write down 2 as next digit of the result. 
Result so far: 41257.592
Deduct 1738 from 2290 and we're left with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Step 12:
869 goes into 5520 6 times with a remainder of 306.
Put 6 as the next digit of the answer. 
Result so far: 41257.5926
Deduct 5214 from 5520 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 13:
869 goes into 3060 3 times with a remainder of 453.
Write down 3 as next digit of the result. 
Result so far: 41257.59263
Subtracting 2607 from 3060 leaves us with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Let's proceed to step 14:
869 can be fit into 4530 5 times, resulting in a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 41257.592635
Subtract 4345 from 4530 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 15:
869 goes into 1850 2 times with a remainder of 112.
The number 2 becomes the next digit in our result. 
Result so far: 41257.5926352
If we take 1738 away from 1850, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 16:
869 goes into 1120 1 times with a remainder of 251.
Use 1 as the next digit of our solution. 
Result so far: 41257.59263521
Subtract 869 from 1120 to get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

The final outcome is 41257.59263521, with a leftover of 2.51e-07.
