We're dividing 170888 by 4 
Our goal is to divide 170888 by 4.

Advancing to step 1:
4 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 4

Let's proceed to step 2:
4 can be fit into 17 4 times, resulting in a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 1 after subtracting 16 from 17.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 4

Step 3:
10 divided by 4 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 42.0
If we take 8 away from 10, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 4

On to step 4:
When dividing 28 by 4, we get 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 427.0
Subtract 28 from 28 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 4

Going ahead to step 5:
The number 4 fits into 8 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 4272.0
If we subtract 8 from 8, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 4

Advancing to step 6:
If we divide 8 by 4, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 42722.0
The remainder is 0 after subtracting 8 from 8.
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 7:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 42722.0
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.

Going ahead to step 8:
When dividing 0 by 4, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 42722.0
Subtract 0 from 0 to 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.

After the division, we end up with 42722.0 and a remainder of 0.0.
