Let's divide 42131483 by 879
The aim is to understand the frequency of 879 in 42131483.

Going ahead to step 1:
If we divide 4 by 879, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 879

Advancing to step 2:
879 can be fit into 42 0 times, resulting in a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 879

Moving on to step 3:
879 can be fit into 421 0 times, resulting in a remainder of 421.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 421 and we're left with 421.
Append the next digit (3) from the dividend to 421 and continue with: 4213 / 879

Let's proceed to step 4:
879 can be fit into 4213 4 times, resulting in a remainder of 697.
The next digit of our result is 4. 
Result so far: 4.0
If we take 3516 away from 4213, we end up with 697.
Fetch the next digit (1) from the dividend, attach it to 697 and continue: 6971 / 879

Going ahead to step 5:
6971 divided by 879 is 7 with a remainder of 818.
The next digit of our result is 7. 
Result so far: 47.0
If we take 6153 away from 6971, we end up with 818.
Include the next digit (4) from the dividend after 818, then repeat: 8184 / 879

Advancing to step 6:
879 goes into 8184 9 times with a remainder of 273.
The number 9 becomes the next digit in our result. 
Result so far: 479.0
The remainder is 273 after subtracting 7911 from 8184.
Bring next digit (8) of the dividend behind the 273 and repeat the process: 2738 / 879

Going ahead to step 7:
When dividing 2738 by 879, we get 3 with a remainder of 101.
Use 3 as the next digit of our solution. 
Result so far: 4793.0
Subtract 2637 from 2738 to get 101.
Bring next digit (3) of the dividend behind the 101 and repeat the process: 1013 / 879

Advancing to step 8:
The number 879 fits into 1013 1 times, leaving a remainder of 134.
Use 1 as the next digit of our solution. 
Result so far: 47931.0
If we take 879 away from 1013, we end up 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.

Advancing to step 9:
879 goes into 1340 1 times with a remainder of 461.
The next digit of our result is 1. 
Result so far: 47931.1
Subtract 879 from 1340 to get 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

On to step 10:
879 can be fit into 4610 5 times, resulting in a remainder of 215.
Write down 5 as next digit of the result. 
Result so far: 47931.15
If we subtract 4395 from 4610, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 11:
879 can be fit into 2150 2 times, resulting in a remainder of 392.
Use 2 as the next digit of our solution. 
Result so far: 47931.152
The remainder is 392 after subtracting 1758 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 12:
3920 divided by 879 is 4 with a remainder of 404.
Write down 4 as next digit of the result. 
Result so far: 47931.1524
If we take 3516 away from 3920, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Step 13:
879 goes into 4040 4 times with a remainder of 524.
Write down 4 as next digit of the result. 
Result so far: 47931.15244
Subtracting 3516 from 4040 leaves us with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Our division results in 47931.15244 with a remaining 0.000524.
