We're dividing 39373146 by 878 
We want to divide 39373146 by 878.

On to step 1:
878 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 878

Step 2:
39 divided by 878 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 878

Let's proceed to step 3:
When dividing 393 by 878, we get 0 with a remainder of 393.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 393 and we're left with 393.
Fetch the next digit (7) from the dividend, attach it to 393 and continue: 3937 / 878

Going ahead to step 4:
If we divide 3937 by 878, we get 4 and a remainder of 425.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 3512 away from 3937, we end up with 425.
Fetch the next digit (3) from the dividend, attach it to 425 and continue: 4253 / 878

Advancing to step 5:
878 can be fit into 4253 4 times, resulting in a remainder of 741.
Put 4 as the next digit of the answer. 
Result so far: 44.0
If we subtract 3512 from 4253, we get 741.
Bring next digit (1) of the dividend behind the 741 and repeat the process: 7411 / 878

Advancing to step 6:
7411 divided by 878 is 8 with a remainder of 387.
Put 8 as the next digit of the answer. 
Result so far: 448.0
If we subtract 7024 from 7411, we get 387.
Append the next digit (4) from the dividend to 387 and continue with: 3874 / 878

Advancing to step 7:
If we divide 3874 by 878, we get 4 and a remainder of 362.
Put 4 as the next digit of the answer. 
Result so far: 4484.0
Subtracting 3512 from 3874 leaves us with 362.
Bring next digit (6) of the dividend behind the 362 and repeat the process: 3626 / 878

Moving on to step 8:
878 can be fit into 3626 4 times, resulting in a remainder of 114.
The number 4 becomes the next digit in our result. 
Result so far: 44844.0
Deduct 3512 from 3626 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 9:
878 can be fit into 1140 1 times, resulting in a remainder of 262.
Use 1 as the next digit of our solution. 
Result so far: 44844.1
If we subtract 878 from 1140, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 10:
The number 878 fits into 2620 2 times, leaving a remainder of 864.
Use 2 as the next digit of our solution. 
Result so far: 44844.12
The remainder is 864 after subtracting 1756 from 2620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

Advancing to step 11:
The number 878 fits into 8640 9 times, leaving a remainder of 738.
Write down 9 as next digit of the result. 
Result so far: 44844.129
Subtract 7902 from 8640 to get 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Let's proceed to step 12:
7380 divided by 878 is 8 with a remainder of 356.
Write down 8 as next digit of the result. 
Result so far: 44844.1298
If we take 7024 away from 7380, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 13:
3560 divided by 878 is 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 44844.12984
If we subtract 3512 from 3560, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 14:
480 divided by 878 is 0 with a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 44844.12984
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 15:
4800 divided by 878 is 5 with a remainder of 410.
Record the quotient 5 as the next digit in the result. 
Result so far: 44844.1298405
If we subtract 4390 from 4800, we get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 16:
The number 878 fits into 4100 4 times, leaving a remainder of 588.
Put 4 as the next digit of the answer. 
Result so far: 44844.12984054
If we take 3512 away from 4100, we end up with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

After the division, we end up with 44844.12984054 and a remainder of 5.88e-07.
