We're dividing 688871 by 4 
We want to figure out the number of times 688871 can be divided by 4.

Step 1:
6 divided by 4 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 4 away from 6, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 4

Going ahead to step 2:
If we divide 28 by 4, we get 7 and a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 28 from 28 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 4

On to step 3:
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: 172.0
The remainder is 0 after subtracting 8 from 8.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 4

On to step 4:
If we divide 8 by 4, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 1722.0
If we take 8 away from 8, we end up with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 4

Step 5:
7 divided by 4 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 17221.0
If we subtract 4 from 7, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 4

Let's proceed to step 6:
When dividing 31 by 4, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 172217.0
Subtract 28 from 31 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
When dividing 30 by 4, we get 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 172217.7
Subtracting 28 from 30 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
When dividing 20 by 4, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 172217.75
Subtracting 20 from 20 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.

Step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 172217.75
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.

On to step 10:
When dividing 0 by 4, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 172217.75
Subtracting 0 from 0 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.

The quotient of the division is 172217.75, and the remainder is 0.0.
