We're dividing 80306158 by 434 
Our goal is to divide 80306158 by 434.

On to step 1:
434 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 434

Moving on to step 2:
The number 434 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Bring next digit (3) of the dividend behind the 80 and repeat the process: 803 / 434

On to step 3:
When dividing 803 by 434, we get 1 with a remainder of 369.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 434 from 803 to get 369.
Grab the next digit (0) from the dividend, add it to 369, then carry on: 3690 / 434

Let's proceed to step 4:
The number 434 fits into 3690 8 times, leaving a remainder of 218.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtracting 3472 from 3690 leaves us with 218.
Grab the next digit (6) from the dividend, add it to 218, then carry on: 2186 / 434

Advancing to step 5:
434 can be fit into 2186 5 times, resulting in a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 185.0
Subtract 2170 from 2186 to get 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 434

Let's proceed to step 6:
434 goes into 161 0 times with a remainder of 161.
Record the quotient 0 as the next digit in the result. 
Result so far: 1850.0
If we take 0 away from 161, we end up with 161.
Include the next digit (5) from the dividend after 161, then repeat: 1615 / 434

Going ahead to step 7:
1615 divided by 434 is 3 with a remainder of 313.
Record the quotient 3 as the next digit in the result. 
Result so far: 18503.0
Subtracting 1302 from 1615 leaves us with 313.
Take the next digit (8) from the dividend and append it to 313, then repeat: 3138 / 434

Step 8:
When dividing 3138 by 434, we get 7 with a remainder of 100.
The next digit of our result is 7. 
Result so far: 185037.0
Deduct 3038 from 3138 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 9:
1000 divided by 434 is 2 with a remainder of 132.
The number 2 becomes the next digit in our result. 
Result so far: 185037.2
The remainder is 132 after subtracting 868 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 10:
434 goes into 1320 3 times with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 185037.23
Subtract 1302 from 1320 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 11:
The number 434 fits into 180 0 times, leaving a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 185037.23
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 12:
434 goes into 1800 4 times with a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 185037.2304
The remainder is 64 after subtracting 1736 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 13:
434 goes into 640 1 times with a remainder of 206.
Use 1 as the next digit of our solution. 
Result so far: 185037.23041
Subtracting 434 from 640 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 14:
2060 divided by 434 is 4 with a remainder of 324.
The number 4 becomes the next digit in our result. 
Result so far: 185037.230414
If we subtract 1736 from 2060, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 15:
434 goes into 3240 7 times with a remainder of 202.
Write down 7 as next digit of the result. 
Result so far: 185037.2304147
The remainder is 202 after subtracting 3038 from 3240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 16:
When dividing 2020 by 434, we get 4 with a remainder of 284.
The number 4 becomes the next digit in our result. 
Result so far: 185037.23041474
If we subtract 1736 from 2020, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

The quotient of the division is 185037.23041474, and the remainder is 2.84e-07.
