We look at the division of 65400525 by 879 
We're looking to find how many times 879 goes into 65400525.

Going ahead to step 1:
When dividing 6 by 879, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 879

Advancing to step 2:
879 goes into 65 0 times with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Append the next digit (4) from the dividend to 65 and continue with: 654 / 879

Moving on to step 3:
879 can be fit into 654 0 times, resulting in a remainder of 654.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 654, we get 654.
Include the next digit (0) from the dividend after 654, then repeat: 6540 / 879

Step 4:
The number 879 fits into 6540 7 times, leaving a remainder of 387.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 6153 from 6540 to get 387.
Append the next digit (0) from the dividend to 387 and continue with: 3870 / 879

Moving on to step 5:
If we divide 3870 by 879, we get 4 and a remainder of 354.
Write down 4 as next digit of the result. 
Result so far: 74.0
Deduct 3516 from 3870 and we're left with 354.
Fetch the next digit (5) from the dividend, attach it to 354 and continue: 3545 / 879

On to step 6:
879 can be fit into 3545 4 times, resulting in a remainder of 29.
The number 4 becomes the next digit in our result. 
Result so far: 744.0
If we subtract 3516 from 3545, we get 29.
Include the next digit (2) from the dividend after 29, then repeat: 292 / 879

On to step 7:
The number 879 fits into 292 0 times, leaving a remainder of 292.
Write down 0 as next digit of the result. 
Result so far: 7440.0
If we take 0 away from 292, we end up with 292.
Bring next digit (5) of the dividend behind the 292 and repeat the process: 2925 / 879

On to step 8:
879 can be fit into 2925 3 times, resulting in a remainder of 288.
The next digit of our result is 3. 
Result so far: 74403.0
If we subtract 2637 from 2925, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 9:
2880 divided by 879 is 3 with a remainder of 243.
Put 3 as the next digit of the answer. 
Result so far: 74403.3
Deduct 2637 from 2880 and we're left with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Going ahead to step 10:
2430 divided by 879 is 2 with a remainder of 672.
The next digit of our result is 2. 
Result so far: 74403.32
If we take 1758 away from 2430, we end up with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Let's proceed to step 11:
The number 879 fits into 6720 7 times, leaving a remainder of 567.
Use 7 as the next digit of our solution. 
Result so far: 74403.327
The remainder is 567 after subtracting 6153 from 6720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Step 12:
When dividing 5670 by 879, we get 6 with a remainder of 396.
The next digit of our result is 6. 
Result so far: 74403.3276
Deduct 5274 from 5670 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 13:
The number 879 fits into 3960 4 times, leaving a remainder of 444.
The number 4 becomes the next digit in our result. 
Result so far: 74403.32764
If we subtract 3516 from 3960, 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.

Let's proceed to step 14:
When dividing 4440 by 879, we get 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 74403.327645
If we take 4395 away from 4440, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 15:
When dividing 450 by 879, we get 0 with a remainder of 450.
Record the quotient 0 as the next digit in the result. 
Result so far: 74403.327645
If we take 0 away from 450, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 16:
If we divide 4500 by 879, we get 5 and a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 74403.32764505
Subtract 4395 from 4500 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final result is 74403.32764505 with a remainder of 1.05e-07.
