We divide 21562789 by 328
The aim is to understand the frequency of 328 in 21562789.

On to step 1:
The number 328 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 328

Moving on to step 2:
The number 328 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 328

Step 3:
The number 328 fits into 215 0 times, leaving a remainder of 215.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 215, we end up with 215.
Include the next digit (6) from the dividend after 215, then repeat: 2156 / 328

Advancing to step 4:
When dividing 2156 by 328, we get 6 with a remainder of 188.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 1968 from 2156 leaves us with 188.
Include the next digit (2) from the dividend after 188, then repeat: 1882 / 328

Moving on to step 5:
1882 divided by 328 is 5 with a remainder of 242.
Write down 5 as next digit of the result. 
Result so far: 65.0
Subtracting 1640 from 1882 leaves us with 242.
Fetch the next digit (7) from the dividend, attach it to 242 and continue: 2427 / 328

Let's proceed to step 6:
328 can be fit into 2427 7 times, resulting in a remainder of 131.
The next digit of our result is 7. 
Result so far: 657.0
Deduct 2296 from 2427 and we're left with 131.
Include the next digit (8) from the dividend after 131, then repeat: 1318 / 328

Moving on to step 7:
328 goes into 1318 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 6574.0
The remainder is 6 after subtracting 1312 from 1318.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 328

On to step 8:
328 can be fit into 69 0 times, resulting in a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 65740.0
If we take 0 away from 69, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 9:
If we divide 690 by 328, we get 2 and a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 65740.2
If we subtract 656 from 690, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
328 can be fit into 340 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 65740.21
If we take 328 away from 340, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
The number 328 fits into 120 0 times, leaving a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 65740.21
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 12:
If we divide 1200 by 328, we get 3 and a remainder of 216.
Record the quotient 3 as the next digit in the result. 
Result so far: 65740.2103
If we subtract 984 from 1200, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 13:
The number 328 fits into 2160 6 times, leaving a remainder of 192.
The number 6 becomes the next digit in our result. 
Result so far: 65740.21036
The remainder is 192 after subtracting 1968 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 14:
The number 328 fits into 1920 5 times, leaving a remainder of 280.
The number 5 becomes the next digit in our result. 
Result so far: 65740.210365
Deduct 1640 from 1920 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 15:
If we divide 2800 by 328, we get 8 and a remainder of 176.
Use 8 as the next digit of our solution. 
Result so far: 65740.2103658
Deduct 2624 from 2800 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 16:
1760 divided by 328 is 5 with a remainder of 120.
Put 5 as the next digit of the answer. 
Result so far: 65740.21036585
Deduct 1640 from 1760 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The quotient of the division is 65740.21036585, and the remainder is 1.2e-07.
