We're dividing 870788 by 4 
We're looking to find how many times 4 goes into 870788.

Going ahead to step 1:
The number 4 fits into 8 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we take 8 away from 8, we end up with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 4

Advancing to step 2:
7 divided by 4 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 4 from 7 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 4

On to step 3:
If we divide 30 by 4, we get 7 and a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 217.0
If we take 28 away from 30, we end up with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 4

On to step 4:
4 goes into 27 6 times with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 2176.0
The remainder is 3 after subtracting 24 from 27.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 4

Advancing to step 5:
The number 4 fits into 38 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 21769.0
Deduct 36 from 38 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 4

Going ahead to step 6:
When dividing 28 by 4, we get 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 217697.0
Subtracting 28 from 28 leaves us 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.

Advancing to step 7:
4 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 217697.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
4 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 217697.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 217697.0 with a remainder of 0.0.
