We look at the division of 1137866 by 489 
Let's see how many times 489 fits into 1137866.

Advancing to step 1:
The number 489 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 489

Step 2:
11 divided by 489 is 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 489

Step 3:
113 divided by 489 is 0 with a remainder of 113.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 113 to get 113.
Include the next digit (7) from the dividend after 113, then repeat: 1137 / 489

Let's proceed to step 4:
489 can be fit into 1137 2 times, resulting in a remainder of 159.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 978 from 1137 and we're left with 159.
Fetch the next digit (8) from the dividend, attach it to 159 and continue: 1598 / 489

Moving on to step 5:
489 can be fit into 1598 3 times, resulting in a remainder of 131.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtract 1467 from 1598 to get 131.
Append the next digit (6) from the dividend to 131 and continue with: 1316 / 489

Step 6:
489 can be fit into 1316 2 times, resulting in a remainder of 338.
Use 2 as the next digit of our solution. 
Result so far: 232.0
Deduct 978 from 1316 and we're left with 338.
Bring next digit (6) of the dividend behind the 338 and repeat the process: 3386 / 489

Going ahead to step 7:
The number 489 fits into 3386 6 times, leaving a remainder of 452.
The next digit of our result is 6. 
Result so far: 2326.0
Subtract 2934 from 3386 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 8:
When dividing 4520 by 489, we get 9 with a remainder of 119.
Write down 9 as next digit of the result. 
Result so far: 2326.9
Subtracting 4401 from 4520 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Let's proceed to step 9:
489 goes into 1190 2 times with a remainder of 212.
The number 2 becomes the next digit in our result. 
Result so far: 2326.92
Subtract 978 from 1190 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 10:
The number 489 fits into 2120 4 times, leaving a remainder of 164.
Put 4 as the next digit of the answer. 
Result so far: 2326.924
The remainder is 164 after subtracting 1956 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 11:
When dividing 1640 by 489, we get 3 with a remainder of 173.
Use 3 as the next digit of our solution. 
Result so far: 2326.9243
Subtract 1467 from 1640 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Moving on to step 12:
The number 489 fits into 1730 3 times, leaving a remainder of 263.
The next digit of our result is 3. 
Result so far: 2326.92433
The remainder is 263 after subtracting 1467 from 1730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

The quotient of the division is 2326.92433, and the remainder is 0.000263.
