We're dividing 870055 by 48 
We're looking to find how many times 48 goes into 870055.

Step 1:
The number 48 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 48

Going ahead to step 2:
The number 48 fits into 87 1 times, leaving a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 48 from 87, we get 39.
Fetch the next digit (0) from the dividend, attach it to 39 and continue: 390 / 48

On to step 3:
If we divide 390 by 48, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 384 from 390, we get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 48

On to step 4:
When dividing 60 by 48, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 181.0
Subtracting 48 from 60 leaves us with 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 48

On to step 5:
The number 48 fits into 125 2 times, leaving a remainder of 29.
Use 2 as the next digit of our solution. 
Result so far: 1812.0
If we subtract 96 from 125, we get 29.
Grab the next digit (5) from the dividend, add it to 29, then carry on: 295 / 48

Going ahead to step 6:
48 can be fit into 295 6 times, resulting in a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 18126.0
Subtract 288 from 295 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
48 can be fit into 70 1 times, resulting in a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 18126.1
If we subtract 48 from 70, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
If we divide 220 by 48, we get 4 and a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 18126.14
If we subtract 192 from 220, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
280 divided by 48 is 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 18126.145
Subtracting 240 from 280 leaves us 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.

On to step 10:
If we divide 400 by 48, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 18126.1458
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.

Advancing to step 11:
The number 48 fits into 160 3 times, leaving a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 18126.14583
Subtract 144 from 160 to 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: 18126.145833
Subtract 144 from 160 to 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.

After the division, we end up with 18126.145833 and a remainder of 1.6e-06.
