The aim is to understand the frequency of 869 in 33172576.

Advancing 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
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 869

Advancing to step 2:
The number 869 fits into 33 0 times, leaving a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 869

Step 3:
869 can be fit into 331 0 times, resulting in a remainder of 331.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 331, we get 331.
Grab the next digit (7) from the dividend, add it to 331, then carry on: 3317 / 869

Advancing to step 4:
When dividing 3317 by 869, we get 3 with a remainder of 710.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 2607 from 3317, we get 710.
Take the next digit (2) from the dividend and append it to 710, then repeat: 7102 / 869

Moving on to step 5:
If we divide 7102 by 869, we get 8 and a remainder of 150.
The next digit of our result is 8. 
Result so far: 38.0
If we subtract 6952 from 7102, we get 150.
Bring next digit (5) of the dividend behind the 150 and repeat the process: 1505 / 869

Advancing to step 6:
869 goes into 1505 1 times with a remainder of 636.
Put 1 as the next digit of the answer. 
Result so far: 381.0
The remainder is 636 after subtracting 869 from 1505.
Take the next digit (7) from the dividend and append it to 636, then repeat: 6367 / 869

Step 7:
869 can be fit into 6367 7 times, resulting in a remainder of 284.
Use 7 as the next digit of our solution. 
Result so far: 3817.0
Subtracting 6083 from 6367 leaves us with 284.
Append the next digit (6) from the dividend to 284 and continue with: 2846 / 869

Advancing to step 8:
869 can be fit into 2846 3 times, resulting in a remainder of 239.
Use 3 as the next digit of our solution. 
Result so far: 38173.0
If we take 2607 away from 2846, we end up with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Moving on to step 9:
The number 869 fits into 2390 2 times, leaving a remainder of 652.
Write down 2 as next digit of the result. 
Result so far: 38173.2
Subtracting 1738 from 2390 leaves us with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Moving on to step 10:
6520 divided by 869 is 7 with a remainder of 437.
Put 7 as the next digit of the answer. 
Result so far: 38173.27
The remainder is 437 after subtracting 6083 from 6520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Step 11:
If we divide 4370 by 869, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 38173.275
The remainder is 25 after subtracting 4345 from 4370.
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 12:
869 goes into 250 0 times with a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 38173.275
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.

Going ahead to step 13:
2500 divided by 869 is 2 with a remainder of 762.
The number 2 becomes the next digit in our result. 
Result so far: 38173.27502
Subtracting 1738 from 2500 leaves us with 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

On to step 14:
When dividing 7620 by 869, we get 8 with a remainder of 668.
Write down 8 as next digit of the result. 
Result so far: 38173.275028
Subtract 6952 from 7620 to get 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

On to step 15:
If we divide 6680 by 869, we get 7 and a remainder of 597.
Put 7 as the next digit of the answer. 
Result so far: 38173.2750287
The remainder is 597 after subtracting 6083 from 6680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Advancing to step 16:
869 goes into 5970 6 times with a remainder of 756.
The next digit of our result is 6. 
Result so far: 38173.27502876
Subtract 5214 from 5970 to get 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Our division results in 38173.27502876 with a remaining 7.56e-07.
