We're dividing 12181816 by 635 
We're looking to find how many times 635 goes into 12181816.

Step 1:
635 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 635

Going ahead to step 2:
The number 635 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 635

Moving on to step 3:
635 can be fit into 121 0 times, resulting in a remainder of 121.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 121 to get 121.
Bring next digit (8) of the dividend behind the 121 and repeat the process: 1218 / 635

Let's proceed to step 4:
635 goes into 1218 1 times with a remainder of 583.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 635 from 1218, we get 583.
Bring next digit (1) of the dividend behind the 583 and repeat the process: 5831 / 635

Going ahead to step 5:
If we divide 5831 by 635, we get 9 and a remainder of 116.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 5715 from 5831 leaves us with 116.
Append the next digit (8) from the dividend to 116 and continue with: 1168 / 635

Going ahead to step 6:
635 goes into 1168 1 times with a remainder of 533.
Use 1 as the next digit of our solution. 
Result so far: 191.0
The remainder is 533 after subtracting 635 from 1168.
Include the next digit (1) from the dividend after 533, then repeat: 5331 / 635

Let's proceed to step 7:
The number 635 fits into 5331 8 times, leaving a remainder of 251.
Write down 8 as next digit of the result. 
Result so far: 1918.0
If we take 5080 away from 5331, we end up with 251.
Take the next digit (6) from the dividend and append it to 251, then repeat: 2516 / 635

Going ahead to step 8:
If we divide 2516 by 635, we get 3 and a remainder of 611.
The next digit of our result is 3. 
Result so far: 19183.0
Deduct 1905 from 2516 and we're left with 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

On to step 9:
6110 divided by 635 is 9 with a remainder of 395.
Put 9 as the next digit of the answer. 
Result so far: 19183.9
The remainder is 395 after subtracting 5715 from 6110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Advancing to step 10:
When dividing 3950 by 635, we get 6 with a remainder of 140.
Put 6 as the next digit of the answer. 
Result so far: 19183.96
The remainder is 140 after subtracting 3810 from 3950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
635 goes into 1400 2 times with a remainder of 130.
Use 2 as the next digit of our solution. 
Result so far: 19183.962
If we subtract 1270 from 1400, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 12:
635 goes into 1300 2 times with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 19183.9622
Subtract 1270 from 1300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 19183.9622, with a leftover of 0.0003.
