We're dividing 39326880 by 881 
The aim is to understand the frequency of 881 in 39326880.

Going ahead to step 1:
3 divided by 881 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 881

Moving on to step 2:
When dividing 39 by 881, we get 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Take the next digit (3) from the dividend and append it to 39, then repeat: 393 / 881

Let's proceed to step 3:
The number 881 fits into 393 0 times, leaving a remainder of 393.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 393, we end up with 393.
Include the next digit (2) from the dividend after 393, then repeat: 3932 / 881

Step 4:
If we divide 3932 by 881, we get 4 and a remainder of 408.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 3524 from 3932 to get 408.
Fetch the next digit (6) from the dividend, attach it to 408 and continue: 4086 / 881

Going ahead to step 5:
If we divide 4086 by 881, we get 4 and a remainder of 562.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we subtract 3524 from 4086, we get 562.
Include the next digit (8) from the dividend after 562, then repeat: 5628 / 881

Step 6:
881 can be fit into 5628 6 times, resulting in a remainder of 342.
The next digit of our result is 6. 
Result so far: 446.0
If we subtract 5286 from 5628, we get 342.
Grab the next digit (8) from the dividend, add it to 342, then carry on: 3428 / 881

Going ahead to step 7:
The number 881 fits into 3428 3 times, leaving a remainder of 785.
Record the quotient 3 as the next digit in the result. 
Result so far: 4463.0
Deduct 2643 from 3428 and we're left with 785.
Take the next digit (0) from the dividend and append it to 785, then repeat: 7850 / 881

Advancing to step 8:
881 can be fit into 7850 8 times, resulting in a remainder of 802.
Put 8 as the next digit of the answer. 
Result so far: 44638.0
If we subtract 7048 from 7850, we get 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

On to step 9:
881 goes into 8020 9 times with a remainder of 91.
Write down 9 as next digit of the result. 
Result so far: 44638.9
Subtract 7929 from 8020 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 10:
910 divided by 881 is 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 44638.91
Subtracting 881 from 910 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 11:
881 can be fit into 290 0 times, resulting in a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 44638.91
If we take 0 away from 290, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 12:
881 can be fit into 2900 3 times, resulting in a remainder of 257.
Use 3 as the next digit of our solution. 
Result so far: 44638.9103
The remainder is 257 after subtracting 2643 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Advancing to step 13:
2570 divided by 881 is 2 with a remainder of 808.
Write down 2 as next digit of the result. 
Result so far: 44638.91032
If we subtract 1762 from 2570, we get 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

Going ahead to step 14:
The number 881 fits into 8080 9 times, leaving a remainder of 151.
The number 9 becomes the next digit in our result. 
Result so far: 44638.910329
Subtract 7929 from 8080 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 15:
When dividing 1510 by 881, we get 1 with a remainder of 629.
The next digit of our result is 1. 
Result so far: 44638.9103291
Deduct 881 from 1510 and we're left with 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

Let's proceed to step 16:
If we divide 6290 by 881, we get 7 and a remainder of 123.
Use 7 as the next digit of our solution. 
Result so far: 44638.91032917
Subtracting 6167 from 6290 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

The final result is 44638.91032917 with a remainder of 1.23e-07.
