We look at the division of 40619366 by 879 
The aim is to understand the frequency of 879 in 40619366.

Step 1:
4 divided by 879 is 0 with 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 (0) of the dividend behind the 4 and repeat the process: 40 / 879

Let's proceed to step 2:
If we divide 40 by 879, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 879

Step 3:
If we divide 406 by 879, we get 0 and a remainder of 406.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 406 leaves us with 406.
Take the next digit (1) from the dividend and append it to 406, then repeat: 4061 / 879

Let's proceed to step 4:
4061 divided by 879 is 4 with a remainder of 545.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 3516 from 4061, we get 545.
Bring next digit (9) of the dividend behind the 545 and repeat the process: 5459 / 879

Advancing to step 5:
The number 879 fits into 5459 6 times, leaving a remainder of 185.
Use 6 as the next digit of our solution. 
Result so far: 46.0
The remainder is 185 after subtracting 5274 from 5459.
Take the next digit (3) from the dividend and append it to 185, then repeat: 1853 / 879

Moving on to step 6:
If we divide 1853 by 879, we get 2 and a remainder of 95.
The next digit of our result is 2. 
Result so far: 462.0
Subtract 1758 from 1853 to get 95.
Fetch the next digit (6) from the dividend, attach it to 95 and continue: 956 / 879

Let's proceed to step 7:
When dividing 956 by 879, we get 1 with a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 4621.0
If we subtract 879 from 956, we get 77.
Include the next digit (6) from the dividend after 77, then repeat: 776 / 879

Step 8:
The number 879 fits into 776 0 times, leaving a remainder of 776.
Put 0 as the next digit of the answer. 
Result so far: 46210.0
If we take 0 away from 776, we end up with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Moving on to step 9:
If we divide 7760 by 879, we get 8 and a remainder of 728.
The number 8 becomes the next digit in our result. 
Result so far: 46210.8
The remainder is 728 after subtracting 7032 from 7760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Step 10:
The number 879 fits into 7280 8 times, leaving a remainder of 248.
Use 8 as the next digit of our solution. 
Result so far: 46210.88
The remainder is 248 after subtracting 7032 from 7280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

After the division, we end up with 46210.88 and a remainder of 0.248.
