We look at the division of 837985 by 33 
The aim is to understand the frequency of 33 in 837985.

Step 1:
8 divided by 33 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 33

Step 2:
33 goes into 83 2 times with a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 66 from 83 to get 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 33

Let's proceed to step 3:
33 goes into 177 5 times with a remainder of 12.
The next digit of our result is 5. 
Result so far: 25.0
If we subtract 165 from 177, we get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 33

Let's proceed to step 4:
33 goes into 129 3 times with a remainder of 30.
The next digit of our result is 3. 
Result so far: 253.0
Subtract 99 from 129 to get 30.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 33

On to step 5:
If we divide 308 by 33, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 2539.0
Deduct 297 from 308 and we're left with 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 33

Step 6:
115 divided by 33 is 3 with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 25393.0
If we subtract 99 from 115, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
If we divide 160 by 33, we get 4 and a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 25393.4
Deduct 132 from 160 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
33 goes into 280 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 25393.48
The remainder is 16 after subtracting 264 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
If we divide 160 by 33, we get 4 and a remainder of 28.
The next digit of our result is 4. 
Result so far: 25393.484
The remainder is 28 after subtracting 132 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
The number 33 fits into 280 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 25393.4848
Deduct 264 from 280 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
33 goes into 160 4 times with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 25393.48484
If we take 132 away from 160, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
If we divide 280 by 33, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 25393.484848
If we take 264 away from 280, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
The number 33 fits into 160 4 times, leaving a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 25393.4848484
If we subtract 132 from 160, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 14:
When dividing 280 by 33, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 25393.48484848
If we take 264 away from 280, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 25393.48484848, with a leftover of 1.6e-08.
