We're dividing 18043144 by 315 
We want to figure out the number of times 18043144 can be divided by 315.

Step 1:
The number 315 fits into 1 0 times, leaving 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.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 315

Going ahead to step 2:
The number 315 fits into 18 0 times, leaving a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 315

Step 3:
The number 315 fits into 180 0 times, leaving a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 180 leaves us with 180.
Append the next digit (4) from the dividend to 180 and continue with: 1804 / 315

Going ahead to step 4:
315 goes into 1804 5 times with a remainder of 229.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 1575 from 1804 to get 229.
Fetch the next digit (3) from the dividend, attach it to 229 and continue: 2293 / 315

Going ahead to step 5:
315 goes into 2293 7 times with a remainder of 88.
The next digit of our result is 7. 
Result so far: 57.0
The remainder is 88 after subtracting 2205 from 2293.
Include the next digit (1) from the dividend after 88, then repeat: 881 / 315

Advancing to step 6:
If we divide 881 by 315, we get 2 and a remainder of 251.
The number 2 becomes the next digit in our result. 
Result so far: 572.0
If we subtract 630 from 881, we get 251.
Append the next digit (4) from the dividend to 251 and continue with: 2514 / 315

Moving on to step 7:
The number 315 fits into 2514 7 times, leaving a remainder of 309.
The next digit of our result is 7. 
Result so far: 5727.0
The remainder is 309 after subtracting 2205 from 2514.
Grab the next digit (4) from the dividend, add it to 309, then carry on: 3094 / 315

Advancing to step 8:
When dividing 3094 by 315, we get 9 with a remainder of 259.
Write down 9 as next digit of the result. 
Result so far: 57279.0
If we take 2835 away from 3094, we end up with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Going ahead to step 9:
315 can be fit into 2590 8 times, resulting in a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 57279.8
The remainder is 70 after subtracting 2520 from 2590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
315 goes into 700 2 times with a remainder of 70.
Use 2 as the next digit of our solution. 
Result so far: 57279.82
If we subtract 630 from 700, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
The number 315 fits into 700 2 times, leaving a remainder of 70.
The next digit of our result is 2. 
Result so far: 57279.822
Subtracting 630 from 700 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 57279.822, with a leftover of 0.007.
