878345 divided by 33 
The aim is to understand the frequency of 33 in 878345.

Advancing to step 1:
When dividing 8 by 33, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 33

On to step 2:
33 can be fit into 87 2 times, resulting in a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 66 from 87, we get 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 33

Advancing to step 3:
33 can be fit into 218 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtract 198 from 218 to get 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 33

Advancing to step 4:
The number 33 fits into 203 6 times, leaving a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 266.0
If we take 198 away from 203, we end up with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 33

Step 5:
The number 33 fits into 54 1 times, leaving a remainder of 21.
The next digit of our result is 1. 
Result so far: 2661.0
Subtracting 33 from 54 leaves us with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 33

On to step 6:
215 divided by 33 is 6 with a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 26616.0
If we take 198 away from 215, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
If we divide 170 by 33, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 26616.5
Deduct 165 from 170 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
33 goes into 50 1 times with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 26616.51
Subtracting 33 from 50 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
33 can be fit into 170 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 26616.515
If we take 165 away from 170, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
33 can be fit into 50 1 times, resulting in a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 26616.5151
Subtract 33 from 50 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 11:
The number 33 fits into 170 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 26616.51515
Deduct 165 from 170 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
33 can be fit into 50 1 times, resulting in a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 26616.515151
If we take 33 away from 50, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 13:
If we divide 170 by 33, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 26616.5151515
Subtract 165 from 170 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
When dividing 50 by 33, we get 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 26616.51515151
Subtract 33 from 50 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The quotient of the division is 26616.51515151, and the remainder is 1.7e-08.
