38706396 ÷ 881 
The aim is to understand the frequency of 881 in 38706396.

On to step 1:
881 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 881

Advancing to step 2:
38 divided by 881 is 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Take the next digit (7) from the dividend and append it to 38, then repeat: 387 / 881

Going ahead to step 3:
881 goes into 387 0 times with a remainder of 387.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 387 after subtracting 0 from 387.
Grab the next digit (0) from the dividend, add it to 387, then carry on: 3870 / 881

Going ahead to step 4:
3870 divided by 881 is 4 with a remainder of 346.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 346 after subtracting 3524 from 3870.
Include the next digit (6) from the dividend after 346, then repeat: 3466 / 881

Advancing to step 5:
881 goes into 3466 3 times with a remainder of 823.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtract 2643 from 3466 to get 823.
Include the next digit (3) from the dividend after 823, then repeat: 8233 / 881

Moving on to step 6:
8233 divided by 881 is 9 with a remainder of 304.
Write down 9 as next digit of the result. 
Result so far: 439.0
Subtracting 7929 from 8233 leaves us with 304.
Include the next digit (9) from the dividend after 304, then repeat: 3049 / 881

Moving on to step 7:
If we divide 3049 by 881, we get 3 and a remainder of 406.
The number 3 becomes the next digit in our result. 
Result so far: 4393.0
Subtract 2643 from 3049 to get 406.
Take the next digit (6) from the dividend and append it to 406, then repeat: 4066 / 881

Going ahead to step 8:
When dividing 4066 by 881, we get 4 with a remainder of 542.
Use 4 as the next digit of our solution. 
Result so far: 43934.0
Subtract 3524 from 4066 to get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Let's proceed to step 9:
The number 881 fits into 5420 6 times, leaving a remainder of 134.
The next digit of our result is 6. 
Result so far: 43934.6
Subtracting 5286 from 5420 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 10:
The number 881 fits into 1340 1 times, leaving a remainder of 459.
Use 1 as the next digit of our solution. 
Result so far: 43934.61
Subtracting 881 from 1340 leaves us with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Going ahead to step 11:
881 goes into 4590 5 times with a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 43934.615
The remainder is 185 after subtracting 4405 from 4590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 12:
881 can be fit into 1850 2 times, resulting in a remainder of 88.
The next digit of our result is 2. 
Result so far: 43934.6152
Subtract 1762 from 1850 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 13:
881 can be fit into 880 0 times, resulting in a remainder of 880.
Use 0 as the next digit of our solution. 
Result so far: 43934.6152
Subtract 0 from 880 to get 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

Moving on to step 14:
If we divide 8800 by 881, we get 9 and a remainder of 871.
Use 9 as the next digit of our solution. 
Result so far: 43934.615209
Deduct 7929 from 8800 and we're left with 871.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8710, and continue the process.

Going ahead to step 15:
If we divide 8710 by 881, we get 9 and a remainder of 781.
The number 9 becomes the next digit in our result. 
Result so far: 43934.6152099
If we subtract 7929 from 8710, we get 781.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7810, and continue the process.

After the division, we end up with 43934.6152099 and a remainder of 7.81e-06.
