Let's divide 42860241 by 489
Our goal is to divide 42860241 by 489.

On to step 1:
4 divided by 489 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 489

Going ahead to step 2:
When dividing 42 by 489, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 489

On to step 3:
428 divided by 489 is 0 with a remainder of 428.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 428 after subtracting 0 from 428.
Bring next digit (6) of the dividend behind the 428 and repeat the process: 4286 / 489

Moving on to step 4:
489 goes into 4286 8 times with a remainder of 374.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 3912 from 4286, we get 374.
Include the next digit (0) from the dividend after 374, then repeat: 3740 / 489

On to step 5:
The number 489 fits into 3740 7 times, leaving a remainder of 317.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we take 3423 away from 3740, we end up with 317.
Take the next digit (2) from the dividend and append it to 317, then repeat: 3172 / 489

Advancing to step 6:
If we divide 3172 by 489, we get 6 and a remainder of 238.
Put 6 as the next digit of the answer. 
Result so far: 876.0
If we take 2934 away from 3172, we end up with 238.
Take the next digit (4) from the dividend and append it to 238, then repeat: 2384 / 489

Going ahead to step 7:
2384 divided by 489 is 4 with a remainder of 428.
The number 4 becomes the next digit in our result. 
Result so far: 8764.0
Deduct 1956 from 2384 and we're left with 428.
Bring next digit (1) of the dividend behind the 428 and repeat the process: 4281 / 489

Moving on to step 8:
4281 divided by 489 is 8 with a remainder of 369.
The next digit of our result is 8. 
Result so far: 87648.0
The remainder is 369 after subtracting 3912 from 4281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Let's proceed to step 9:
The number 489 fits into 3690 7 times, leaving a remainder of 267.
Record the quotient 7 as the next digit in the result. 
Result so far: 87648.7
If we take 3423 away from 3690, we end up with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Going ahead to step 10:
When dividing 2670 by 489, we get 5 with a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 87648.75
Deduct 2445 from 2670 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 11:
489 goes into 2250 4 times with a remainder of 294.
The number 4 becomes the next digit in our result. 
Result so far: 87648.754
The remainder is 294 after subtracting 1956 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 12:
489 goes into 2940 6 times with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 87648.7546
Subtracting 2934 from 2940 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
60 divided by 489 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 87648.7546
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
If we divide 600 by 489, we get 1 and a remainder of 111.
Record the quotient 1 as the next digit in the result. 
Result so far: 87648.754601
Deduct 489 from 600 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 15:
489 goes into 1110 2 times with a remainder of 132.
The next digit of our result is 2. 
Result so far: 87648.7546012
Subtract 978 from 1110 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 16:
When dividing 1320 by 489, we get 2 with a remainder of 342.
Record the quotient 2 as the next digit in the result. 
Result so far: 87648.75460122
Subtract 978 from 1320 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

The final outcome is 87648.75460122, with a leftover of 3.42e-07.
