We're dividing 21607074 by 876 
The aim is to understand the frequency of 876 in 21607074.

Advancing to step 1:
2 divided by 876 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 876

Let's proceed to step 2:
If we divide 21 by 876, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 876

On to step 3:
216 divided by 876 is 0 with a remainder of 216.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 216 leaves us with 216.
Take the next digit (0) from the dividend and append it to 216, then repeat: 2160 / 876

Going ahead to step 4:
If we divide 2160 by 876, we get 2 and a remainder of 408.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1752 from 2160 to get 408.
Include the next digit (7) from the dividend after 408, then repeat: 4087 / 876

Moving on to step 5:
876 can be fit into 4087 4 times, resulting in a remainder of 583.
The next digit of our result is 4. 
Result so far: 24.0
If we subtract 3504 from 4087, we get 583.
Include the next digit (0) from the dividend after 583, then repeat: 5830 / 876

Step 6:
If we divide 5830 by 876, we get 6 and a remainder of 574.
Record the quotient 6 as the next digit in the result. 
Result so far: 246.0
Subtracting 5256 from 5830 leaves us with 574.
Include the next digit (7) from the dividend after 574, then repeat: 5747 / 876

Let's proceed to step 7:
The number 876 fits into 5747 6 times, leaving a remainder of 491.
Record the quotient 6 as the next digit in the result. 
Result so far: 2466.0
Subtract 5256 from 5747 to get 491.
Include the next digit (4) from the dividend after 491, then repeat: 4914 / 876

Step 8:
If we divide 4914 by 876, we get 5 and a remainder of 534.
Write down 5 as next digit of the result. 
Result so far: 24665.0
If we take 4380 away from 4914, we end up with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Let's proceed to step 9:
5340 divided by 876 is 6 with a remainder of 84.
The next digit of our result is 6. 
Result so far: 24665.6
The remainder is 84 after subtracting 5256 from 5340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 10:
The number 876 fits into 840 0 times, leaving a remainder of 840.
Record the quotient 0 as the next digit in the result. 
Result so far: 24665.6
Deduct 0 from 840 and we're left with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Moving on to step 11:
8400 divided by 876 is 9 with a remainder of 516.
Put 9 as the next digit of the answer. 
Result so far: 24665.609
If we subtract 7884 from 8400, we get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

On to step 12:
876 can be fit into 5160 5 times, resulting in a remainder of 780.
Use 5 as the next digit of our solution. 
Result so far: 24665.6095
If we take 4380 away from 5160, we end up with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Let's proceed to step 13:
When dividing 7800 by 876, we get 8 with a remainder of 792.
Write down 8 as next digit of the result. 
Result so far: 24665.60958
Subtracting 7008 from 7800 leaves us with 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Let's proceed to step 14:
If we divide 7920 by 876, we get 9 and a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 24665.609589
If we subtract 7884 from 7920, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 15:
876 can be fit into 360 0 times, resulting in a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 24665.609589
Subtracting 0 from 360 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 16:
When dividing 3600 by 876, we get 4 with a remainder of 96.
The next digit of our result is 4. 
Result so far: 24665.60958904
If we take 3504 away from 3600, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Our division results in 24665.60958904 with a remaining 9.6e-08.
