We look at the division of 12183499 by 658 
We're looking to find how many times 658 goes into 12183499.

Advancing to step 1:
If we divide 1 by 658, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 658

Going ahead to step 2:
If we divide 12 by 658, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 658

On to step 3:
The number 658 fits into 121 0 times, leaving a remainder of 121.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 121 to get 121.
Append the next digit (8) from the dividend to 121 and continue with: 1218 / 658

Going ahead to step 4:
658 goes into 1218 1 times with a remainder of 560.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 658 from 1218, we get 560.
Append the next digit (3) from the dividend to 560 and continue with: 5603 / 658

Step 5:
When dividing 5603 by 658, we get 8 with a remainder of 339.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we take 5264 away from 5603, we end up with 339.
Append the next digit (4) from the dividend to 339 and continue with: 3394 / 658

Moving on to step 6:
658 goes into 3394 5 times with a remainder of 104.
The next digit of our result is 5. 
Result so far: 185.0
Deduct 3290 from 3394 and we're left with 104.
Fetch the next digit (9) from the dividend, attach it to 104 and continue: 1049 / 658

Going ahead to step 7:
If we divide 1049 by 658, we get 1 and a remainder of 391.
Use 1 as the next digit of our solution. 
Result so far: 1851.0
If we take 658 away from 1049, we end up with 391.
Grab the next digit (9) from the dividend, add it to 391, then carry on: 3919 / 658

Advancing to step 8:
658 can be fit into 3919 5 times, resulting in a remainder of 629.
The next digit of our result is 5. 
Result so far: 18515.0
Subtracting 3290 from 3919 leaves us with 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

Going ahead to step 9:
The number 658 fits into 6290 9 times, leaving a remainder of 368.
The number 9 becomes the next digit in our result. 
Result so far: 18515.9
If we subtract 5922 from 6290, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 10:
658 can be fit into 3680 5 times, resulting in a remainder of 390.
The next digit of our result is 5. 
Result so far: 18515.95
Subtract 3290 from 3680 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 11:
3900 divided by 658 is 5 with a remainder of 610.
Record the quotient 5 as the next digit in the result. 
Result so far: 18515.955
Subtracting 3290 from 3900 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

The final result is 18515.955 with a remainder of 0.061.
