861984 divided by 48 
We're looking to find how many times 48 goes into 861984.

On to step 1:
The number 48 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 48

Let's proceed to step 2:
48 goes into 86 1 times with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 48 from 86 leaves us with 38.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 48

Let's proceed to step 3:
48 can be fit into 381 7 times, resulting in a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 45 after subtracting 336 from 381.
Take the next digit (9) from the dividend and append it to 45, then repeat: 459 / 48

Step 4:
If we divide 459 by 48, we get 9 and a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 179.0
The remainder is 27 after subtracting 432 from 459.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 48

Let's proceed to step 5:
The number 48 fits into 278 5 times, leaving a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 1795.0
If we subtract 240 from 278, we get 38.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 48

On to step 6:
The number 48 fits into 384 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 17958.0
The remainder is 0 after subtracting 384 from 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
48 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17958.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 48 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17958.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 17958.0 and a remainder of 0.0.
