We're dividing 217420 by 4 
We want to figure out the number of times 217420 can be divided by 4.

Advancing to step 1:
4 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 4

Advancing to step 2:
The number 4 fits into 21 5 times, leaving a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 20 away from 21, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 4

Going ahead to step 3:
17 divided by 4 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
Subtracting 16 from 17 leaves us with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 4

Going ahead to step 4:
When dividing 14 by 4, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 543.0
Deduct 12 from 14 and we're left with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 4

On to step 5:
22 divided by 4 is 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 5435.0
If we subtract 20 from 22, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 4

Going ahead to step 6:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 54355.0
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.

Moving on to step 7:
4 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 54355.0
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.

On to step 8:
If we divide 0 by 4, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 54355.0
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.

The final result is 54355.0 with a remainder of 0.0.
