We're dividing 42452004 by 881 
The aim is to understand the frequency of 881 in 42452004.

Step 1:
The number 881 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 881

Advancing to step 2:
42 divided by 881 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Append the next digit (4) from the dividend to 42 and continue with: 424 / 881

Let's proceed to step 3:
424 divided by 881 is 0 with a remainder of 424.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 424 to get 424.
Fetch the next digit (5) from the dividend, attach it to 424 and continue: 4245 / 881

Moving on to step 4:
When dividing 4245 by 881, we get 4 with a remainder of 721.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 3524 from 4245 and we're left with 721.
Fetch the next digit (2) from the dividend, attach it to 721 and continue: 7212 / 881

Step 5:
881 goes into 7212 8 times with a remainder of 164.
The next digit of our result is 8. 
Result so far: 48.0
Deduct 7048 from 7212 and we're left with 164.
Append the next digit (0) from the dividend to 164 and continue with: 1640 / 881

Going ahead to step 6:
1640 divided by 881 is 1 with a remainder of 759.
The next digit of our result is 1. 
Result so far: 481.0
If we subtract 881 from 1640, we get 759.
Grab the next digit (0) from the dividend, add it to 759, then carry on: 7590 / 881

On to step 7:
881 can be fit into 7590 8 times, resulting in a remainder of 542.
Write down 8 as next digit of the result. 
Result so far: 4818.0
If we subtract 7048 from 7590, we get 542.
Grab the next digit (4) from the dividend, add it to 542, then carry on: 5424 / 881

Moving on to step 8:
The number 881 fits into 5424 6 times, leaving a remainder of 138.
Use 6 as the next digit of our solution. 
Result so far: 48186.0
Subtract 5286 from 5424 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 9:
When dividing 1380 by 881, we get 1 with a remainder of 499.
Use 1 as the next digit of our solution. 
Result so far: 48186.1
If we take 881 away from 1380, we end up with 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Advancing to step 10:
If we divide 4990 by 881, we get 5 and a remainder of 585.
Use 5 as the next digit of our solution. 
Result so far: 48186.15
The remainder is 585 after subtracting 4405 from 4990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Let's proceed to step 11:
If we divide 5850 by 881, we get 6 and a remainder of 564.
The next digit of our result is 6. 
Result so far: 48186.156
If we subtract 5286 from 5850, we get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Moving on to step 12:
When dividing 5640 by 881, we get 6 with a remainder of 354.
Use 6 as the next digit of our solution. 
Result so far: 48186.1566
The remainder is 354 after subtracting 5286 from 5640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

The final result is 48186.1566 with a remainder of 0.00354.
