We divide 635871 by 4
We want to divide 635871 by 4.

Let's proceed to step 1:
The number 4 fits into 6 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 4 from 6 to get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 4

Let's proceed to step 2:
The number 4 fits into 23 5 times, leaving a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 3 after subtracting 20 from 23.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 4

Let's proceed to step 3:
4 can be fit into 35 8 times, resulting in a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
Subtracting 32 from 35 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 4

Step 4:
If we divide 38 by 4, we get 9 and a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 1589.0
The remainder is 2 after subtracting 36 from 38.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 4

Moving on to step 5:
27 divided by 4 is 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 15896.0
If we subtract 24 from 27, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 4

Advancing to step 6:
When dividing 31 by 4, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 158967.0
If we subtract 28 from 31, we 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:
If we divide 30 by 4, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 158967.7
Subtract 28 from 30 to get 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:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 158967.75
Deduct 20 from 20 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.

Step 9:
0 divided by 4 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 158967.75
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.

Advancing to step 10:
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: 158967.75
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 final result is 158967.75 with a remainder of 0.0.
