Let's divide 850435 by 4
We're looking to find how many times 4 goes into 850435.

Moving on to step 1:
The number 4 fits into 8 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 8 from 8, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 4

Going ahead to step 2:
The number 4 fits into 5 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 4 from 5, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 4

On to step 3:
4 goes into 10 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 212.0
Subtracting 8 from 10 leaves us with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 4

Moving on to step 4:
If we divide 24 by 4, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 2126.0
Subtract 24 from 24 to get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 4

On to step 5:
The number 4 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 21260.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 4

Step 6:
The number 4 fits into 35 8 times, leaving a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 212608.0
The remainder is 3 after subtracting 32 from 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
4 goes into 30 7 times with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 212608.7
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
If we divide 20 by 4, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 212608.75
Subtract 20 from 20 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.

Going ahead to step 9:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 212608.75
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.

Advancing to step 10:
If we divide 0 by 4, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 212608.75
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 212608.75, and the remainder is 0.0.
