We look at the division of 18302320 by 434 
We're looking to find how many times 434 goes into 18302320.

On to step 1:
434 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 434

Going ahead to step 2:
When dividing 18 by 434, we get 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 434

Step 3:
The number 434 fits into 183 0 times, leaving a remainder of 183.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 183 and we're left with 183.
Append the next digit (0) from the dividend to 183 and continue with: 1830 / 434

Let's proceed to step 4:
When dividing 1830 by 434, we get 4 with a remainder of 94.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 1736 from 1830 and we're left with 94.
Fetch the next digit (2) from the dividend, attach it to 94 and continue: 942 / 434

Advancing to step 5:
434 goes into 942 2 times with a remainder of 74.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we subtract 868 from 942, we get 74.
Fetch the next digit (3) from the dividend, attach it to 74 and continue: 743 / 434

Let's proceed to step 6:
If we divide 743 by 434, we get 1 and a remainder of 309.
Record the quotient 1 as the next digit in the result. 
Result so far: 421.0
The remainder is 309 after subtracting 434 from 743.
Take the next digit (2) from the dividend and append it to 309, then repeat: 3092 / 434

Going ahead to step 7:
3092 divided by 434 is 7 with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 4217.0
Subtracting 3038 from 3092 leaves us with 54.
Grab the next digit (0) from the dividend, add it to 54, then carry on: 540 / 434

Going ahead to step 8:
If we divide 540 by 434, we get 1 and a remainder of 106.
Write down 1 as next digit of the result. 
Result so far: 42171.0
If we subtract 434 from 540, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 9:
If we divide 1060 by 434, we get 2 and a remainder of 192.
The number 2 becomes the next digit in our result. 
Result so far: 42171.2
Subtract 868 from 1060 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 10:
1920 divided by 434 is 4 with a remainder of 184.
Write down 4 as next digit of the result. 
Result so far: 42171.24
If we subtract 1736 from 1920, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 11:
If we divide 1840 by 434, we get 4 and a remainder of 104.
Write down 4 as next digit of the result. 
Result so far: 42171.244
If we take 1736 away from 1840, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Our division results in 42171.244 with a remaining 0.0104.
