Let's divide 680470 by 4
We want to figure out the number of times 680470 can be divided by 4.

Let's proceed to step 1:
6 divided by 4 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 4 from 6 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 4

Going ahead to step 2:
4 goes into 28 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Deduct 28 from 28 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 4

Advancing to step 3:
When dividing 0 by 4, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 170.0
If we subtract 0 from 0, we get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 4

Moving on to step 4:
4 goes into 4 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1701.0
Subtract 4 from 4 to get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 4

Let's proceed to step 5:
When dividing 7 by 4, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 17011.0
If we take 4 away from 7, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 4

On to step 6:
If we divide 30 by 4, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 170117.0
Deduct 28 from 30 and we're left 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.

Step 7:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 170117.5
If we take 20 away from 20, we end up 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.

Going ahead to step 8:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 170117.5
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.

Moving on to step 9:
0 divided by 4 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 170117.5
If we take 0 away from 0, we end up 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 outcome is 170117.5, with a leftover of 0.0.
