We look at the division of 840957 by 4 
We're looking to find how many times 4 goes into 840957.

Advancing to step 1:
4 goes into 8 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 0 after subtracting 8 from 8.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 4

Going ahead to step 2:
If we divide 4 by 4, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 4 from 4 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 4

Going ahead to step 3:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 210.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 4

Moving on to step 4:
4 can be fit into 9 2 times, resulting in a remainder of 1.
The next digit of our result is 2. 
Result so far: 2102.0
The remainder is 1 after subtracting 8 from 9.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 4

Let's proceed to step 5:
4 goes into 15 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 21023.0
The remainder is 3 after subtracting 12 from 15.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 4

On to step 6:
4 goes into 37 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 210239.0
If we subtract 36 from 37, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
4 goes into 10 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 210239.2
If we take 8 away from 10, we end up 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.

Going ahead 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: 210239.25
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.

Let's proceed to step 9:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 210239.25
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:
When dividing 0 by 4, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 210239.25
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 quotient of the division is 210239.25, and the remainder is 0.0.
