We're dividing 80430116 by 103 
We want to divide 80430116 by 103.

On to step 1:
8 divided by 103 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 103

Advancing to step 2:
103 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Append the next digit (4) from the dividend to 80 and continue with: 804 / 103

Going ahead to step 3:
If we divide 804 by 103, we get 7 and a remainder of 83.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 83 after subtracting 721 from 804.
Take the next digit (3) from the dividend and append it to 83, then repeat: 833 / 103

Step 4:
103 can be fit into 833 8 times, resulting in a remainder of 9.
The next digit of our result is 8. 
Result so far: 78.0
Subtracting 824 from 833 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 103

Going ahead to step 5:
The number 103 fits into 90 0 times, leaving a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 780.0
If we subtract 0 from 90, we get 90.
Append the next digit (1) from the dividend to 90 and continue with: 901 / 103

Moving on to step 6:
When dividing 901 by 103, we get 8 with a remainder of 77.
The number 8 becomes the next digit in our result. 
Result so far: 7808.0
If we subtract 824 from 901, we get 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 103

Going ahead to step 7:
The number 103 fits into 771 7 times, leaving a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 78087.0
If we subtract 721 from 771, we get 50.
Fetch the next digit (6) from the dividend, attach it to 50 and continue: 506 / 103

Going ahead to step 8:
When dividing 506 by 103, we get 4 with a remainder of 94.
Record the quotient 4 as the next digit in the result. 
Result so far: 780874.0
If we take 412 away from 506, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 9:
940 divided by 103 is 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 780874.9
If we subtract 927 from 940, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 10:
When dividing 130 by 103, we get 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 780874.91
The remainder is 27 after subtracting 103 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 11:
103 can be fit into 270 2 times, resulting in a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 780874.912
The remainder is 64 after subtracting 206 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
The number 103 fits into 640 6 times, leaving a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 780874.9126
If we take 618 away from 640, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 13:
When dividing 220 by 103, we get 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 780874.91262
Subtract 206 from 220 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
If we divide 140 by 103, we get 1 and a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 780874.912621
Deduct 103 from 140 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 15:
370 divided by 103 is 3 with a remainder of 61.
The next digit of our result is 3. 
Result so far: 780874.9126213
Subtract 309 from 370 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 16:
103 can be fit into 610 5 times, resulting in a remainder of 95.
Put 5 as the next digit of the answer. 
Result so far: 780874.91262135
Subtracting 515 from 610 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

The final result is 780874.91262135 with a remainder of 9.5e-08.
