We look at the division of 41596591 by 879 
The aim is to understand the frequency of 879 in 41596591.

Let's proceed to step 1:
If we divide 4 by 879, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 879

Step 2:
If we divide 41 by 879, we get 0 and a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 41 and we're left with 41.
Bring next digit (5) of the dividend behind the 41 and repeat the process: 415 / 879

Step 3:
When dividing 415 by 879, we get 0 with a remainder of 415.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 415 to get 415.
Include the next digit (9) from the dividend after 415, then repeat: 4159 / 879

Going ahead to step 4:
The number 879 fits into 4159 4 times, leaving a remainder of 643.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 643 after subtracting 3516 from 4159.
Take the next digit (6) from the dividend and append it to 643, then repeat: 6436 / 879

Going ahead to step 5:
When dividing 6436 by 879, we get 7 with a remainder of 283.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Subtracting 6153 from 6436 leaves us with 283.
Append the next digit (5) from the dividend to 283 and continue with: 2835 / 879

Going ahead to step 6:
When dividing 2835 by 879, we get 3 with a remainder of 198.
The number 3 becomes the next digit in our result. 
Result so far: 473.0
If we subtract 2637 from 2835, we get 198.
Fetch the next digit (9) from the dividend, attach it to 198 and continue: 1989 / 879

Advancing to step 7:
If we divide 1989 by 879, we get 2 and a remainder of 231.
Record the quotient 2 as the next digit in the result. 
Result so far: 4732.0
Deduct 1758 from 1989 and we're left with 231.
Take the next digit (1) from the dividend and append it to 231, then repeat: 2311 / 879

Moving on to step 8:
If we divide 2311 by 879, we get 2 and a remainder of 553.
Use 2 as the next digit of our solution. 
Result so far: 47322.0
The remainder is 553 after subtracting 1758 from 2311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Moving on to step 9:
5530 divided by 879 is 6 with a remainder of 256.
Write down 6 as next digit of the result. 
Result so far: 47322.6
If we subtract 5274 from 5530, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 10:
2560 divided by 879 is 2 with a remainder of 802.
Use 2 as the next digit of our solution. 
Result so far: 47322.62
The remainder is 802 after subtracting 1758 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

Step 11:
879 can be fit into 8020 9 times, resulting in a remainder of 109.
The next digit of our result is 9. 
Result so far: 47322.629
If we take 7911 away from 8020, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 12:
When dividing 1090 by 879, we get 1 with a remainder of 211.
Use 1 as the next digit of our solution. 
Result so far: 47322.6291
Deduct 879 from 1090 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Going ahead to step 13:
The number 879 fits into 2110 2 times, leaving a remainder of 352.
The number 2 becomes the next digit in our result. 
Result so far: 47322.62912
Subtracting 1758 from 2110 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 14:
3520 divided by 879 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 47322.629124
The remainder is 4 after subtracting 3516 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 15:
40 divided by 879 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 47322.629124
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 16:
879 can be fit into 400 0 times, resulting in a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 47322.629124
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

In conclusion, the division gives 47322.629124 with a balance of 4e-07.
