40879663 divided by 103 
Our goal is to divide 40879663 by 103.

Step 1:
The number 103 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 103

Advancing to step 2:
If we divide 40 by 103, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 103

Step 3:
When dividing 408 by 103, we get 3 with a remainder of 99.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 309 away from 408, we end up with 99.
Include the next digit (7) from the dividend after 99, then repeat: 997 / 103

Moving on to step 4:
103 goes into 997 9 times with a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 39.0
The remainder is 70 after subtracting 927 from 997.
Grab the next digit (9) from the dividend, add it to 70, then carry on: 709 / 103

On to step 5:
The number 103 fits into 709 6 times, leaving a remainder of 91.
Write down 6 as next digit of the result. 
Result so far: 396.0
Subtracting 618 from 709 leaves us with 91.
Bring next digit (6) of the dividend behind the 91 and repeat the process: 916 / 103

Step 6:
916 divided by 103 is 8 with a remainder of 92.
The next digit of our result is 8. 
Result so far: 3968.0
Subtracting 824 from 916 leaves us with 92.
Take the next digit (6) from the dividend and append it to 92, then repeat: 926 / 103

Step 7:
103 goes into 926 8 times with a remainder of 102.
The number 8 becomes the next digit in our result. 
Result so far: 39688.0
If we take 824 away from 926, we end up with 102.
Grab the next digit (3) from the dividend, add it to 102, then carry on: 1023 / 103

Step 8:
103 goes into 1023 9 times with a remainder of 96.
Record the quotient 9 as the next digit in the result. 
Result so far: 396889.0
Subtract 927 from 1023 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 9:
If we divide 960 by 103, we get 9 and a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 396889.9
Deduct 927 from 960 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 10:
The number 103 fits into 330 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 396889.93
Subtract 309 from 330 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 11:
103 goes into 210 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 396889.932
Subtract 206 from 210 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
103 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 396889.932
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
When dividing 400 by 103, we get 3 with a remainder of 91.
The number 3 becomes the next digit in our result. 
Result so far: 396889.93203
If we subtract 309 from 400, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 14:
910 divided by 103 is 8 with a remainder of 86.
Record the quotient 8 as the next digit in the result. 
Result so far: 396889.932038
Subtracting 824 from 910 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 15:
860 divided by 103 is 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 396889.9320388
The remainder is 36 after subtracting 824 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 396889.9320388 with a remaining 3.6e-07.
