22531573 divided by 321 
The aim is to understand the frequency of 321 in 22531573.

On to step 1:
The number 321 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 321

Going ahead to step 2:
321 can be fit into 22 0 times, resulting in a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 22 and we're left with 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 321

Step 3:
If we divide 225 by 321, we get 0 and a remainder of 225.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 225 and we're left with 225.
Grab the next digit (3) from the dividend, add it to 225, then carry on: 2253 / 321

Advancing to step 4:
321 goes into 2253 7 times with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 6 after subtracting 2247 from 2253.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 321

Going ahead to step 5:
321 goes into 61 0 times with a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
If we take 0 away from 61, we end up with 61.
Bring next digit (5) of the dividend behind the 61 and repeat the process: 615 / 321

Step 6:
When dividing 615 by 321, we get 1 with a remainder of 294.
Put 1 as the next digit of the answer. 
Result so far: 701.0
Subtracting 321 from 615 leaves us with 294.
Grab the next digit (7) from the dividend, add it to 294, then carry on: 2947 / 321

Step 7:
If we divide 2947 by 321, we get 9 and a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 7019.0
If we subtract 2889 from 2947, we get 58.
Grab the next digit (3) from the dividend, add it to 58, then carry on: 583 / 321

Going ahead to step 8:
583 divided by 321 is 1 with a remainder of 262.
Use 1 as the next digit of our solution. 
Result so far: 70191.0
If we subtract 321 from 583, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 9:
When dividing 2620 by 321, we get 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 70191.8
The remainder is 52 after subtracting 2568 from 2620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
321 can be fit into 520 1 times, resulting in a remainder of 199.
Use 1 as the next digit of our solution. 
Result so far: 70191.81
The remainder is 199 after subtracting 321 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Let's proceed to step 11:
1990 divided by 321 is 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 70191.816
Subtract 1926 from 1990 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
If we divide 640 by 321, we get 1 and a remainder of 319.
Use 1 as the next digit of our solution. 
Result so far: 70191.8161
Deduct 321 from 640 and we're left with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Step 13:
3190 divided by 321 is 9 with a remainder of 301.
The next digit of our result is 9. 
Result so far: 70191.81619
Deduct 2889 from 3190 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 14:
When dividing 3010 by 321, we get 9 with a remainder of 121.
Record the quotient 9 as the next digit in the result. 
Result so far: 70191.816199
Deduct 2889 from 3010 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

The quotient of the division is 70191.816199, and the remainder is 1.21e-05.
