42500771 ÷ 878 
The aim is to understand the frequency of 878 in 42500771.

Going ahead to step 1:
If we divide 4 by 878, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 878

Step 2:
878 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 878

Let's proceed to step 3:
878 can be fit into 425 0 times, resulting in a remainder of 425.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 425 to get 425.
Include the next digit (0) from the dividend after 425, then repeat: 4250 / 878

Step 4:
When dividing 4250 by 878, we get 4 with a remainder of 738.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 738 after subtracting 3512 from 4250.
Fetch the next digit (0) from the dividend, attach it to 738 and continue: 7380 / 878

Step 5:
878 goes into 7380 8 times with a remainder of 356.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we take 7024 away from 7380, we end up with 356.
Grab the next digit (7) from the dividend, add it to 356, then carry on: 3567 / 878

Moving on to step 6:
If we divide 3567 by 878, we get 4 and a remainder of 55.
Record the quotient 4 as the next digit in the result. 
Result so far: 484.0
Subtract 3512 from 3567 to get 55.
Grab the next digit (7) from the dividend, add it to 55, then carry on: 557 / 878

Let's proceed to step 7:
878 can be fit into 557 0 times, resulting in a remainder of 557.
Use 0 as the next digit of our solution. 
Result so far: 4840.0
If we subtract 0 from 557, we get 557.
Take the next digit (1) from the dividend and append it to 557, then repeat: 5571 / 878

Going ahead to step 8:
If we divide 5571 by 878, we get 6 and a remainder of 303.
The number 6 becomes the next digit in our result. 
Result so far: 48406.0
If we take 5268 away from 5571, we end up with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Step 9:
If we divide 3030 by 878, we get 3 and a remainder of 396.
Record the quotient 3 as the next digit in the result. 
Result so far: 48406.3
Subtract 2634 from 3030 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Going ahead to step 10:
3960 divided by 878 is 4 with a remainder of 448.
Write down 4 as next digit of the result. 
Result so far: 48406.34
Deduct 3512 from 3960 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 11:
878 goes into 4480 5 times with a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 48406.345
Deduct 4390 from 4480 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 12:
878 can be fit into 900 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 48406.3451
The remainder is 22 after subtracting 878 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
878 goes into 220 0 times with a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 48406.3451
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 14:
878 goes into 2200 2 times with a remainder of 444.
Put 2 as the next digit of the answer. 
Result so far: 48406.345102
If we subtract 1756 from 2200, we get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

On to step 15:
4440 divided by 878 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 48406.3451025
Subtract 4390 from 4440 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 16:
The number 878 fits into 500 0 times, leaving a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 48406.3451025
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final result is 48406.3451025 with a remainder of 5e-07.
