We're dividing 40397880 by 886 
Let's see how many times 886 fits into 40397880.

Moving on to step 1:
4 divided by 886 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 886

Going ahead to step 2:
If we divide 40 by 886, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 886

Advancing to step 3:
886 can be fit into 403 0 times, resulting in a remainder of 403.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 403 and we're left with 403.
Include the next digit (9) from the dividend after 403, then repeat: 4039 / 886

Advancing to step 4:
886 goes into 4039 4 times with a remainder of 495.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 3544 from 4039 to get 495.
Include the next digit (7) from the dividend after 495, then repeat: 4957 / 886

Step 5:
4957 divided by 886 is 5 with a remainder of 527.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
If we take 4430 away from 4957, we end up with 527.
Include the next digit (8) from the dividend after 527, then repeat: 5278 / 886

Moving on to step 6:
The number 886 fits into 5278 5 times, leaving a remainder of 848.
Use 5 as the next digit of our solution. 
Result so far: 455.0
If we subtract 4430 from 5278, we get 848.
Include the next digit (8) from the dividend after 848, then repeat: 8488 / 886

Going ahead to step 7:
The number 886 fits into 8488 9 times, leaving a remainder of 514.
Use 9 as the next digit of our solution. 
Result so far: 4559.0
The remainder is 514 after subtracting 7974 from 8488.
Grab the next digit (0) from the dividend, add it to 514, then carry on: 5140 / 886

Step 8:
886 goes into 5140 5 times with a remainder of 710.
Record the quotient 5 as the next digit in the result. 
Result so far: 45595.0
If we take 4430 away from 5140, we end up with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Moving on to step 9:
7100 divided by 886 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 45595.8
The remainder is 12 after subtracting 7088 from 7100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
The number 886 fits into 120 0 times, leaving a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 45595.8
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
886 goes into 1200 1 times with a remainder of 314.
Record the quotient 1 as the next digit in the result. 
Result so far: 45595.801
Subtract 886 from 1200 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

On to step 12:
886 goes into 3140 3 times with a remainder of 482.
Record the quotient 3 as the next digit in the result. 
Result so far: 45595.8013
The remainder is 482 after subtracting 2658 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Step 13:
The number 886 fits into 4820 5 times, leaving a remainder of 390.
Use 5 as the next digit of our solution. 
Result so far: 45595.80135
Deduct 4430 from 4820 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 14:
3900 divided by 886 is 4 with a remainder of 356.
Put 4 as the next digit of the answer. 
Result so far: 45595.801354
Subtracting 3544 from 3900 leaves us 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 15:
When dividing 3560 by 886, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 45595.8013544
If we subtract 3544 from 3560, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 45595.8013544 with a remaining 1.6e-07.
