We look at the division of 18686144 by 310 
Our goal is to divide 18686144 by 310.

Moving on to step 1:
310 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 310

Moving on to step 2:
310 can be fit into 18 0 times, resulting in a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 310

Moving on to step 3:
The number 310 fits into 186 0 times, leaving a remainder of 186.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 186 leaves us with 186.
Fetch the next digit (8) from the dividend, attach it to 186 and continue: 1868 / 310

On to step 4:
310 can be fit into 1868 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 1860 from 1868 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 310

Let's proceed to step 5:
When dividing 86 by 310, we get 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 60.0
If we subtract 0 from 86, we get 86.
Include the next digit (1) from the dividend after 86, then repeat: 861 / 310

Moving on to step 6:
310 can be fit into 861 2 times, resulting in a remainder of 241.
Use 2 as the next digit of our solution. 
Result so far: 602.0
If we subtract 620 from 861, we get 241.
Grab the next digit (4) from the dividend, add it to 241, then carry on: 2414 / 310

Moving on to step 7:
310 goes into 2414 7 times with a remainder of 244.
The next digit of our result is 7. 
Result so far: 6027.0
If we take 2170 away from 2414, we end up with 244.
Grab the next digit (4) from the dividend, add it to 244, then carry on: 2444 / 310

On to step 8:
When dividing 2444 by 310, we get 7 with a remainder of 274.
Put 7 as the next digit of the answer. 
Result so far: 60277.0
Subtracting 2170 from 2444 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 9:
310 goes into 2740 8 times with a remainder of 260.
Use 8 as the next digit of our solution. 
Result so far: 60277.8
Subtracting 2480 from 2740 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 10:
310 goes into 2600 8 times with a remainder of 120.
Use 8 as the next digit of our solution. 
Result so far: 60277.88
Subtract 2480 from 2600 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The quotient of the division is 60277.88, and the remainder is 0.12.
