We look at the division of 25660103 by 886 
The aim is to understand the frequency of 886 in 25660103.

Going ahead to step 1:
886 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 886

Step 2:
886 can be fit into 25 0 times, resulting in a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Append the next digit (6) from the dividend to 25 and continue with: 256 / 886

Moving on to step 3:
256 divided by 886 is 0 with a remainder of 256.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 256 leaves us with 256.
Fetch the next digit (6) from the dividend, attach it to 256 and continue: 2566 / 886

Let's proceed to step 4:
2566 divided by 886 is 2 with a remainder of 794.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1772 from 2566, we get 794.
Grab the next digit (0) from the dividend, add it to 794, then carry on: 7940 / 886

Moving on to step 5:
The number 886 fits into 7940 8 times, leaving a remainder of 852.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 852 after subtracting 7088 from 7940.
Append the next digit (1) from the dividend to 852 and continue with: 8521 / 886

On to step 6:
If we divide 8521 by 886, we get 9 and a remainder of 547.
Use 9 as the next digit of our solution. 
Result so far: 289.0
If we subtract 7974 from 8521, we get 547.
Append the next digit (0) from the dividend to 547 and continue with: 5470 / 886

On to step 7:
If we divide 5470 by 886, we get 6 and a remainder of 154.
Write down 6 as next digit of the result. 
Result so far: 2896.0
Subtract 5316 from 5470 to get 154.
Fetch the next digit (3) from the dividend, attach it to 154 and continue: 1543 / 886

On to step 8:
The number 886 fits into 1543 1 times, leaving a remainder of 657.
Use 1 as the next digit of our solution. 
Result so far: 28961.0
The remainder is 657 after subtracting 886 from 1543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Let's proceed to step 9:
When dividing 6570 by 886, we get 7 with a remainder of 368.
Record the quotient 7 as the next digit in the result. 
Result so far: 28961.7
If we take 6202 away from 6570, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 10:
If we divide 3680 by 886, we get 4 and a remainder of 136.
Put 4 as the next digit of the answer. 
Result so far: 28961.74
Deduct 3544 from 3680 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 11:
If we divide 1360 by 886, we get 1 and a remainder of 474.
Put 1 as the next digit of the answer. 
Result so far: 28961.741
The remainder is 474 after subtracting 886 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Let's proceed to step 12:
The number 886 fits into 4740 5 times, leaving a remainder of 310.
Put 5 as the next digit of the answer. 
Result so far: 28961.7415
Subtracting 4430 from 4740 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 13:
When dividing 3100 by 886, we get 3 with a remainder of 442.
Put 3 as the next digit of the answer. 
Result so far: 28961.74153
The remainder is 442 after subtracting 2658 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Moving on to step 14:
4420 divided by 886 is 4 with a remainder of 876.
The next digit of our result is 4. 
Result so far: 28961.741534
Subtracting 3544 from 4420 leaves us with 876.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8760, and continue the process.

Let's proceed to step 15:
886 can be fit into 8760 9 times, resulting in a remainder of 786.
Use 9 as the next digit of our solution. 
Result so far: 28961.7415349
Subtract 7974 from 8760 to get 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

Going ahead to step 16:
The number 886 fits into 7860 8 times, leaving a remainder of 772.
The next digit of our result is 8. 
Result so far: 28961.74153498
The remainder is 772 after subtracting 7088 from 7860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

The final outcome is 28961.74153498, with a leftover of 7.72e-07.
