We look at the division of 48391790 by 881 
The aim is to understand the frequency of 881 in 48391790.

Step 1:
4 divided by 881 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 881

Moving on to step 2:
When dividing 48 by 881, we get 0 with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Fetch the next digit (3) from the dividend, attach it to 48 and continue: 483 / 881

Let's proceed to step 3:
483 divided by 881 is 0 with a remainder of 483.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 483, we get 483.
Grab the next digit (9) from the dividend, add it to 483, then carry on: 4839 / 881

Step 4:
If we divide 4839 by 881, we get 5 and a remainder of 434.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 4405 from 4839, we get 434.
Take the next digit (1) from the dividend and append it to 434, then repeat: 4341 / 881

Let's proceed to step 5:
881 can be fit into 4341 4 times, resulting in a remainder of 817.
The next digit of our result is 4. 
Result so far: 54.0
If we subtract 3524 from 4341, we get 817.
Append the next digit (7) from the dividend to 817 and continue with: 8177 / 881

Step 6:
The number 881 fits into 8177 9 times, leaving a remainder of 248.
Write down 9 as next digit of the result. 
Result so far: 549.0
Deduct 7929 from 8177 and we're left with 248.
Include the next digit (9) from the dividend after 248, then repeat: 2489 / 881

Step 7:
881 goes into 2489 2 times with a remainder of 727.
Record the quotient 2 as the next digit in the result. 
Result so far: 5492.0
Deduct 1762 from 2489 and we're left with 727.
Append the next digit (0) from the dividend to 727 and continue with: 7270 / 881

Moving on to step 8:
If we divide 7270 by 881, we get 8 and a remainder of 222.
Put 8 as the next digit of the answer. 
Result so far: 54928.0
The remainder is 222 after subtracting 7048 from 7270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Moving on to step 9:
881 can be fit into 2220 2 times, resulting in a remainder of 458.
Use 2 as the next digit of our solution. 
Result so far: 54928.2
The remainder is 458 after subtracting 1762 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Moving on to step 10:
881 can be fit into 4580 5 times, resulting in a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 54928.25
If we take 4405 away from 4580, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 11:
When dividing 1750 by 881, we get 1 with a remainder of 869.
The next digit of our result is 1. 
Result so far: 54928.251
The remainder is 869 after subtracting 881 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8690, and continue the process.

Moving on to step 12:
When dividing 8690 by 881, we get 9 with a remainder of 761.
Record the quotient 9 as the next digit in the result. 
Result so far: 54928.2519
Deduct 7929 from 8690 and we're left with 761.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7610, and continue the process.

Let's proceed to step 13:
7610 divided by 881 is 8 with a remainder of 562.
Put 8 as the next digit of the answer. 
Result so far: 54928.25198
If we subtract 7048 from 7610, we get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Advancing to step 14:
881 can be fit into 5620 6 times, resulting in a remainder of 334.
Write down 6 as next digit of the result. 
Result so far: 54928.251986
The remainder is 334 after subtracting 5286 from 5620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Let's proceed to step 15:
881 goes into 3340 3 times with a remainder of 697.
Put 3 as the next digit of the answer. 
Result so far: 54928.2519863
Subtracting 2643 from 3340 leaves us with 697.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6970, and continue the process.

Moving on to step 16:
The number 881 fits into 6970 7 times, leaving a remainder of 803.
Write down 7 as next digit of the result. 
Result so far: 54928.25198637
Deduct 6167 from 6970 and we're left with 803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8030, and continue the process.

The final result is 54928.25198637 with a remainder of 8.03e-07.
