We look at the division of 18210904 by 434 
Let's see how many times 434 fits into 18210904.

Advancing to step 1:
434 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 434

Let's proceed to step 2:
434 can be fit into 18 0 times, resulting in a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 434

Let's proceed to step 3:
434 goes into 182 0 times with a remainder of 182.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 182 after subtracting 0 from 182.
Grab the next digit (1) from the dividend, add it to 182, then carry on: 1821 / 434

Step 4:
1821 divided by 434 is 4 with a remainder of 85.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 1736 from 1821 leaves us with 85.
Append the next digit (0) from the dividend to 85 and continue with: 850 / 434

Going ahead to step 5:
The number 434 fits into 850 1 times, leaving a remainder of 416.
The next digit of our result is 1. 
Result so far: 41.0
If we take 434 away from 850, we end up with 416.
Include the next digit (9) from the dividend after 416, then repeat: 4169 / 434

Let's proceed to step 6:
If we divide 4169 by 434, we get 9 and a remainder of 263.
Record the quotient 9 as the next digit in the result. 
Result so far: 419.0
Subtracting 3906 from 4169 leaves us with 263.
Bring next digit (0) of the dividend behind the 263 and repeat the process: 2630 / 434

Step 7:
434 goes into 2630 6 times with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 4196.0
Subtracting 2604 from 2630 leaves us with 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 434

Advancing to step 8:
264 divided by 434 is 0 with a remainder of 264.
Put 0 as the next digit of the answer. 
Result so far: 41960.0
Subtract 0 from 264 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 9:
If we divide 2640 by 434, we get 6 and a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 41960.6
If we take 2604 away from 2640, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
The number 434 fits into 360 0 times, leaving a remainder of 360.
The next digit of our result is 0. 
Result so far: 41960.6
Subtracting 0 from 360 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 11:
The number 434 fits into 3600 8 times, leaving a remainder of 128.
Write down 8 as next digit of the result. 
Result so far: 41960.608
Subtracting 3472 from 3600 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 12:
If we divide 1280 by 434, we get 2 and a remainder of 412.
Write down 2 as next digit of the result. 
Result so far: 41960.6082
Subtract 868 from 1280 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Step 13:
If we divide 4120 by 434, we get 9 and a remainder of 214.
Use 9 as the next digit of our solution. 
Result so far: 41960.60829
The remainder is 214 after subtracting 3906 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 14:
434 goes into 2140 4 times with a remainder of 404.
The next digit of our result is 4. 
Result so far: 41960.608294
If we take 1736 away from 2140, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 15:
When dividing 4040 by 434, we get 9 with a remainder of 134.
Write down 9 as next digit of the result. 
Result so far: 41960.6082949
Subtracting 3906 from 4040 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 16:
The number 434 fits into 1340 3 times, leaving a remainder of 38.
The next digit of our result is 3. 
Result so far: 41960.60829493
If we subtract 1302 from 1340, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 41960.60829493 and a remainder of 3.8e-08.
