81478689 ÷ 103 
We want to divide 81478689 by 103.

Step 1:
103 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 103

Advancing to step 2:
If we divide 81 by 103, we get 0 and a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (4) from the dividend, attach it to 81 and continue: 814 / 103

Moving on to step 3:
103 can be fit into 814 7 times, resulting in a remainder of 93.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 93 after subtracting 721 from 814.
Grab the next digit (7) from the dividend, add it to 93, then carry on: 937 / 103

On to step 4:
103 can be fit into 937 9 times, resulting in a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 79.0
The remainder is 10 after subtracting 927 from 937.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 103

Moving on to step 5:
If we divide 108 by 103, we get 1 and a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 791.0
Subtracting 103 from 108 leaves us with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 103

Going ahead to step 6:
If we divide 56 by 103, we get 0 and a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 7910.0
If we take 0 away from 56, we end up with 56.
Fetch the next digit (8) from the dividend, attach it to 56 and continue: 568 / 103

Advancing to step 7:
103 can be fit into 568 5 times, resulting in a remainder of 53.
Put 5 as the next digit of the answer. 
Result so far: 79105.0
Subtracting 515 from 568 leaves us with 53.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 103

Going ahead to step 8:
103 goes into 539 5 times with a remainder of 24.
Write down 5 as next digit of the result. 
Result so far: 791055.0
Subtract 515 from 539 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
103 can be fit into 240 2 times, resulting in a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 791055.2
The remainder is 34 after subtracting 206 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
103 can be fit into 340 3 times, resulting in a remainder of 31.
The next digit of our result is 3. 
Result so far: 791055.23
Deduct 309 from 340 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 11:
103 goes into 310 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 791055.233
If we subtract 309 from 310, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 791055.233 and a remainder of 0.0001.
