21780227 divided by 875 
The aim is to understand the frequency of 875 in 21780227.

Let's proceed to step 1:
875 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 875

On to step 2:
The number 875 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 875

Let's proceed to step 3:
875 goes into 217 0 times with a remainder of 217.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 217, we end up with 217.
Include the next digit (8) from the dividend after 217, then repeat: 2178 / 875

Advancing to step 4:
875 goes into 2178 2 times with a remainder of 428.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 1750 from 2178, we get 428.
Include the next digit (0) from the dividend after 428, then repeat: 4280 / 875

Step 5:
875 can be fit into 4280 4 times, resulting in a remainder of 780.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtract 3500 from 4280 to get 780.
Grab the next digit (2) from the dividend, add it to 780, then carry on: 7802 / 875

Step 6:
The number 875 fits into 7802 8 times, leaving a remainder of 802.
Use 8 as the next digit of our solution. 
Result so far: 248.0
Subtract 7000 from 7802 to get 802.
Append the next digit (2) from the dividend to 802 and continue with: 8022 / 875

Let's proceed to step 7:
875 can be fit into 8022 9 times, resulting in a remainder of 147.
Put 9 as the next digit of the answer. 
Result so far: 2489.0
If we take 7875 away from 8022, we end up with 147.
Include the next digit (7) from the dividend after 147, then repeat: 1477 / 875

Step 8:
If we divide 1477 by 875, we get 1 and a remainder of 602.
Record the quotient 1 as the next digit in the result. 
Result so far: 24891.0
If we subtract 875 from 1477, we get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Going ahead to step 9:
875 goes into 6020 6 times with a remainder of 770.
Use 6 as the next digit of our solution. 
Result so far: 24891.6
Deduct 5250 from 6020 and we're left with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Step 10:
When dividing 7700 by 875, we get 8 with a remainder of 700.
The number 8 becomes the next digit in our result. 
Result so far: 24891.68
Subtracting 7000 from 7700 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 11:
875 goes into 7000 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 24891.688
Deduct 7000 from 7000 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 24891.688 with a balance of 0.0.
