We look at the division of 58453657 by 881 
The aim is to understand the frequency of 881 in 58453657.

Moving on to step 1:
881 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 881

Step 2:
881 can be fit into 58 0 times, resulting in a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Take the next digit (4) from the dividend and append it to 58, then repeat: 584 / 881

Advancing to step 3:
When dividing 584 by 881, we get 0 with a remainder of 584.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 584 leaves us with 584.
Fetch the next digit (5) from the dividend, attach it to 584 and continue: 5845 / 881

Going ahead to step 4:
If we divide 5845 by 881, we get 6 and a remainder of 559.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 5286 from 5845, we get 559.
Include the next digit (3) from the dividend after 559, then repeat: 5593 / 881

On to step 5:
5593 divided by 881 is 6 with a remainder of 307.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
If we take 5286 away from 5593, we end up with 307.
Append the next digit (6) from the dividend to 307 and continue with: 3076 / 881

Let's proceed to step 6:
If we divide 3076 by 881, we get 3 and a remainder of 433.
The next digit of our result is 3. 
Result so far: 663.0
Subtract 2643 from 3076 to get 433.
Bring next digit (5) of the dividend behind the 433 and repeat the process: 4335 / 881

Let's proceed to step 7:
4335 divided by 881 is 4 with a remainder of 811.
Use 4 as the next digit of our solution. 
Result so far: 6634.0
The remainder is 811 after subtracting 3524 from 4335.
Include the next digit (7) from the dividend after 811, then repeat: 8117 / 881

Advancing to step 8:
881 goes into 8117 9 times with a remainder of 188.
Use 9 as the next digit of our solution. 
Result so far: 66349.0
Deduct 7929 from 8117 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 9:
1880 divided by 881 is 2 with a remainder of 118.
Record the quotient 2 as the next digit in the result. 
Result so far: 66349.2
Subtract 1762 from 1880 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 10:
1180 divided by 881 is 1 with a remainder of 299.
The number 1 becomes the next digit in our result. 
Result so far: 66349.21
Subtracting 881 from 1180 leaves us with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Advancing to step 11:
The number 881 fits into 2990 3 times, leaving a remainder of 347.
Record the quotient 3 as the next digit in the result. 
Result so far: 66349.213
Subtracting 2643 from 2990 leaves us with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Step 12:
If we divide 3470 by 881, we get 3 and a remainder of 827.
The next digit of our result is 3. 
Result so far: 66349.2133
Deduct 2643 from 3470 and we're left with 827.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8270, and continue the process.

After the division, we end up with 66349.2133 and a remainder of 0.00827.
