We're dividing 856379 by 4 
We want to figure out the number of times 856379 can be divided by 4.

Step 1:
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: 2.0
If we take 8 away from 8, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 4

Going ahead to step 2:
4 can be fit into 5 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 4 from 5 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 4

Advancing to step 3:
When dividing 16 by 4, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 214.0
The remainder is 0 after subtracting 16 from 16.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 4

Step 4:
If we divide 3 by 4, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 2140.0
Subtract 0 from 3 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 4

Let's proceed to step 5:
The number 4 fits into 37 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 21409.0
Subtract 36 from 37 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 4

Advancing to step 6:
The number 4 fits into 19 4 times, leaving a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 214094.0
Deduct 16 from 19 and we're left with 3.
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:
If we divide 30 by 4, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 214094.7
If we subtract 28 from 30, we 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.

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: 214094.75
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.

On to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 214094.75
Deduct 0 from 0 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.

Let's proceed to step 10:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 214094.75
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.

The quotient of the division is 214094.75, and the remainder is 0.0.
