We're dividing 66845361 by 322 
The aim is to understand the frequency of 322 in 66845361.

On to step 1:
6 divided by 322 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 322

On to step 2:
When dividing 66 by 322, we get 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Bring next digit (8) of the dividend behind the 66 and repeat the process: 668 / 322

Step 3:
The number 322 fits into 668 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 24 after subtracting 644 from 668.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 322

On to step 4:
The number 322 fits into 244 0 times, leaving a remainder of 244.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 244 and we're left with 244.
Grab the next digit (5) from the dividend, add it to 244, then carry on: 2445 / 322

Step 5:
If we divide 2445 by 322, we get 7 and a remainder of 191.
Use 7 as the next digit of our solution. 
Result so far: 207.0
Deduct 2254 from 2445 and we're left with 191.
Grab the next digit (3) from the dividend, add it to 191, then carry on: 1913 / 322

Step 6:
1913 divided by 322 is 5 with a remainder of 303.
Use 5 as the next digit of our solution. 
Result so far: 2075.0
Subtracting 1610 from 1913 leaves us with 303.
Include the next digit (6) from the dividend after 303, then repeat: 3036 / 322

Going ahead to step 7:
The number 322 fits into 3036 9 times, leaving a remainder of 138.
Put 9 as the next digit of the answer. 
Result so far: 20759.0
Subtract 2898 from 3036 to get 138.
Fetch the next digit (1) from the dividend, attach it to 138 and continue: 1381 / 322

Moving on to step 8:
1381 divided by 322 is 4 with a remainder of 93.
Put 4 as the next digit of the answer. 
Result so far: 207594.0
If we subtract 1288 from 1381, we get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 9:
If we divide 930 by 322, we get 2 and a remainder of 286.
The next digit of our result is 2. 
Result so far: 207594.2
Deduct 644 from 930 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 10:
322 can be fit into 2860 8 times, resulting in a remainder of 284.
Put 8 as the next digit of the answer. 
Result so far: 207594.28
Subtract 2576 from 2860 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 11:
322 can be fit into 2840 8 times, resulting in a remainder of 264.
The next digit of our result is 8. 
Result so far: 207594.288
If we take 2576 away from 2840, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Our division results in 207594.288 with a remaining 0.0264.
