21841725 divided by 868 
The aim is to understand the frequency of 868 in 21841725.

Let's proceed to step 1:
If we divide 2 by 868, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 868

Going ahead to step 2:
If we divide 21 by 868, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 868

Going ahead to step 3:
868 can be fit into 218 0 times, resulting in a remainder of 218.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 218, we end up with 218.
Append the next digit (4) from the dividend to 218 and continue with: 2184 / 868

Advancing to step 4:
868 can be fit into 2184 2 times, resulting in a remainder of 448.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 448 after subtracting 1736 from 2184.
Include the next digit (1) from the dividend after 448, then repeat: 4481 / 868

Moving on to step 5:
868 goes into 4481 5 times with a remainder of 141.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 4340 from 4481 to get 141.
Include the next digit (7) from the dividend after 141, then repeat: 1417 / 868

Step 6:
868 can be fit into 1417 1 times, resulting in a remainder of 549.
The number 1 becomes the next digit in our result. 
Result so far: 251.0
Subtract 868 from 1417 to get 549.
Include the next digit (2) from the dividend after 549, then repeat: 5492 / 868

Let's proceed to step 7:
The number 868 fits into 5492 6 times, leaving a remainder of 284.
Put 6 as the next digit of the answer. 
Result so far: 2516.0
Deduct 5208 from 5492 and we're left with 284.
Fetch the next digit (5) from the dividend, attach it to 284 and continue: 2845 / 868

Step 8:
868 can be fit into 2845 3 times, resulting in a remainder of 241.
The next digit of our result is 3. 
Result so far: 25163.0
Subtract 2604 from 2845 to get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Step 9:
868 goes into 2410 2 times with a remainder of 674.
The number 2 becomes the next digit in our result. 
Result so far: 25163.2
Deduct 1736 from 2410 and we're left with 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Step 10:
6740 divided by 868 is 7 with a remainder of 664.
The number 7 becomes the next digit in our result. 
Result so far: 25163.27
If we subtract 6076 from 6740, we get 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Step 11:
If we divide 6640 by 868, we get 7 and a remainder of 564.
Write down 7 as next digit of the result. 
Result so far: 25163.277
Deduct 6076 from 6640 and we're left with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Our division results in 25163.277 with a remaining 0.0564.
