25684751 divided by 872 
The aim is to understand the frequency of 872 in 25684751.

Going ahead to step 1:
872 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 872

Step 2:
The number 872 fits into 25 0 times, leaving a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Fetch the next digit (6) from the dividend, attach it to 25 and continue: 256 / 872

On to step 3:
The number 872 fits into 256 0 times, leaving a remainder of 256.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 256 leaves us with 256.
Grab the next digit (8) from the dividend, add it to 256, then carry on: 2568 / 872

Going ahead to step 4:
The number 872 fits into 2568 2 times, leaving a remainder of 824.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1744 from 2568 to get 824.
Grab the next digit (4) from the dividend, add it to 824, then carry on: 8244 / 872

On to step 5:
If we divide 8244 by 872, we get 9 and a remainder of 396.
The next digit of our result is 9. 
Result so far: 29.0
The remainder is 396 after subtracting 7848 from 8244.
Append the next digit (7) from the dividend to 396 and continue with: 3967 / 872

Step 6:
872 can be fit into 3967 4 times, resulting in a remainder of 479.
Put 4 as the next digit of the answer. 
Result so far: 294.0
Deduct 3488 from 3967 and we're left with 479.
Bring next digit (5) of the dividend behind the 479 and repeat the process: 4795 / 872

Let's proceed to step 7:
If we divide 4795 by 872, we get 5 and a remainder of 435.
Use 5 as the next digit of our solution. 
Result so far: 2945.0
Deduct 4360 from 4795 and we're left with 435.
Include the next digit (1) from the dividend after 435, then repeat: 4351 / 872

Going ahead to step 8:
872 can be fit into 4351 4 times, resulting in a remainder of 863.
Record the quotient 4 as the next digit in the result. 
Result so far: 29454.0
The remainder is 863 after subtracting 3488 from 4351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8630, and continue the process.

Step 9:
If we divide 8630 by 872, we get 9 and a remainder of 782.
Use 9 as the next digit of our solution. 
Result so far: 29454.9
Deduct 7848 from 8630 and we're left with 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

On to step 10:
When dividing 7820 by 872, we get 8 with a remainder of 844.
Record the quotient 8 as the next digit in the result. 
Result so far: 29454.98
If we take 6976 away from 7820, we end up with 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

Let's proceed to step 11:
872 can be fit into 8440 9 times, resulting in a remainder of 592.
Record the quotient 9 as the next digit in the result. 
Result so far: 29454.989
The remainder is 592 after subtracting 7848 from 8440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Moving on to step 12:
872 goes into 5920 6 times with a remainder of 688.
The next digit of our result is 6. 
Result so far: 29454.9896
Deduct 5232 from 5920 and we're left with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Moving on to step 13:
The number 872 fits into 6880 7 times, leaving a remainder of 776.
Record the quotient 7 as the next digit in the result. 
Result so far: 29454.98967
Subtract 6104 from 6880 to get 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Step 14:
The number 872 fits into 7760 8 times, leaving a remainder of 784.
Put 8 as the next digit of the answer. 
Result so far: 29454.989678
Subtract 6976 from 7760 to get 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Moving on to step 15:
The number 872 fits into 7840 8 times, leaving a remainder of 864.
Record the quotient 8 as the next digit in the result. 
Result so far: 29454.9896788
Subtracting 6976 from 7840 leaves us with 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

After the division, we end up with 29454.9896788 and a remainder of 8.64e-06.
