We divide 870289 by 48
We want to divide 870289 by 48.

Step 1:
If we divide 8 by 48, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 48

On to step 2:
48 can be fit into 87 1 times, resulting in a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 48 away from 87, we end up with 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 48

Moving on to step 3:
When dividing 390 by 48, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we take 384 away from 390, we end up with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 48

Advancing to step 4:
If we divide 62 by 48, we get 1 and a remainder of 14.
The next digit of our result is 1. 
Result so far: 181.0
Subtract 48 from 62 to get 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 48

Step 5:
148 divided by 48 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 1813.0
If we take 144 away from 148, we end up with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 48

Going ahead to step 6:
The number 48 fits into 49 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 18131.0
Subtract 48 from 49 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
48 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 18131.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 48, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 18131.02
If we take 96 away from 100, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
If we divide 40 by 48, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 18131.02
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
When dividing 400 by 48, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 18131.0208
Subtracting 384 from 400 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
If we divide 160 by 48, we get 3 and a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 18131.02083
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
48 goes into 160 3 times with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 18131.020833
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 18131.020833, with a leftover of 1.6e-06.
