879 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 879

Going ahead to step 2:
When dividing 35 by 879, we get 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 879

Advancing to step 3:
358 divided by 879 is 0 with a remainder of 358.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 358 to get 358.
Fetch the next digit (5) from the dividend, attach it to 358 and continue: 3585 / 879

Let's proceed to step 4:
The number 879 fits into 3585 4 times, leaving a remainder of 69.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 3516 from 3585 leaves us with 69.
Grab the next digit (6) from the dividend, add it to 69, then carry on: 696 / 879

Advancing to step 5:
696 divided by 879 is 0 with a remainder of 696.
Use 0 as the next digit of our solution. 
Result so far: 40.0
The remainder is 696 after subtracting 0 from 696.
Bring next digit (1) of the dividend behind the 696 and repeat the process: 6961 / 879

On to step 6:
If we divide 6961 by 879, we get 7 and a remainder of 808.
Use 7 as the next digit of our solution. 
Result so far: 407.0
Subtracting 6153 from 6961 leaves us with 808.
Fetch the next digit (4) from the dividend, attach it to 808 and continue: 8084 / 879

Moving on to step 7:
If we divide 8084 by 879, we get 9 and a remainder of 173.
Put 9 as the next digit of the answer. 
Result so far: 4079.0
Deduct 7911 from 8084 and we're left with 173.
Grab the next digit (9) from the dividend, add it to 173, then carry on: 1739 / 879

Advancing to step 8:
When dividing 1739 by 879, we get 1 with a remainder of 860.
Write down 1 as next digit of the result. 
Result so far: 40791.0
Subtract 879 from 1739 to get 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Going ahead to step 9:
The number 879 fits into 8600 9 times, leaving a remainder of 689.
Put 9 as the next digit of the answer. 
Result so far: 40791.9
Deduct 7911 from 8600 and we're left with 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Moving on to step 10:
The number 879 fits into 6890 7 times, leaving a remainder of 737.
Record the quotient 7 as the next digit in the result. 
Result so far: 40791.97
Subtract 6153 from 6890 to get 737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

On to step 11:
879 can be fit into 7370 8 times, resulting in a remainder of 338.
Use 8 as the next digit of our solution. 
Result so far: 40791.978
Subtracting 7032 from 7370 leaves us with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Step 12:
3380 divided by 879 is 3 with a remainder of 743.
The number 3 becomes the next digit in our result. 
Result so far: 40791.9783
Subtract 2637 from 3380 to get 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

Advancing to step 13:
879 can be fit into 7430 8 times, resulting in a remainder of 398.
Record the quotient 8 as the next digit in the result. 
Result so far: 40791.97838
If we take 7032 away from 7430, we end up with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 14:
The number 879 fits into 3980 4 times, leaving a remainder of 464.
Put 4 as the next digit of the answer. 
Result so far: 40791.978384
Subtract 3516 from 3980 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

On to step 15:
If we divide 4640 by 879, we get 5 and a remainder of 245.
Use 5 as the next digit of our solution. 
Result so far: 40791.9783845
Subtracting 4395 from 4640 leaves us with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 16:
When dividing 2450 by 879, we get 2 with a remainder of 692.
Record the quotient 2 as the next digit in the result. 
Result so far: 40791.97838452
Subtracting 1758 from 2450 leaves us with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

The final result is 40791.97838452 with a remainder of 6.92e-07.
