We look at the division of 12459683 by 186 
Our goal is to divide 12459683 by 186.

Advancing to step 1:
If we divide 1 by 186, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 186

On to step 2:
The number 186 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
If we subtract 0 from 12, we get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 186

Advancing to step 3:
The number 186 fits into 124 0 times, leaving a remainder of 124.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 124, we end up with 124.
Include the next digit (5) from the dividend after 124, then repeat: 1245 / 186

Going ahead to step 4:
When dividing 1245 by 186, we get 6 with a remainder of 129.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 1116 away from 1245, we end up with 129.
Include the next digit (9) from the dividend after 129, then repeat: 1299 / 186

Step 5:
If we divide 1299 by 186, we get 6 and a remainder of 183.
Write down 6 as next digit of the result. 
Result so far: 66.0
If we take 1116 away from 1299, we end up with 183.
Fetch the next digit (6) from the dividend, attach it to 183 and continue: 1836 / 186

Going ahead to step 6:
186 goes into 1836 9 times with a remainder of 162.
Put 9 as the next digit of the answer. 
Result so far: 669.0
If we take 1674 away from 1836, we end up with 162.
Take the next digit (8) from the dividend and append it to 162, then repeat: 1628 / 186

Advancing to step 7:
186 goes into 1628 8 times with a remainder of 140.
The next digit of our result is 8. 
Result so far: 6698.0
Subtracting 1488 from 1628 leaves us with 140.
Include the next digit (3) from the dividend after 140, then repeat: 1403 / 186

Let's proceed to step 8:
The number 186 fits into 1403 7 times, leaving a remainder of 101.
Put 7 as the next digit of the answer. 
Result so far: 66987.0
If we subtract 1302 from 1403, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 9:
The number 186 fits into 1010 5 times, leaving a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 66987.5
If we subtract 930 from 1010, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
The number 186 fits into 800 4 times, leaving a remainder of 56.
The next digit of our result is 4. 
Result so far: 66987.54
Subtracting 744 from 800 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
If we divide 560 by 186, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 66987.543
The remainder is 2 after subtracting 558 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
186 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 66987.543
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
186 can be fit into 200 1 times, resulting in a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 66987.54301
The remainder is 14 after subtracting 186 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
186 can be fit into 140 0 times, resulting in a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 66987.54301
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 15:
When dividing 1400 by 186, we get 7 with a remainder of 98.
The number 7 becomes the next digit in our result. 
Result so far: 66987.5430107
Deduct 1302 from 1400 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 16:
The number 186 fits into 980 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 66987.54301075
Subtracting 930 from 980 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 66987.54301075 and a remainder of 5e-08.
