We look at the division of 680743 by 4 
We're looking to find how many times 4 goes into 680743.

Step 1:
6 divided by 4 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 4 from 6 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 4

Let's proceed 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
If we subtract 28 from 28, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 4

Going ahead to step 3:
When dividing 0 by 4, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 170.0
If we subtract 0 from 0, we get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 4

Advancing to step 4:
The number 4 fits into 7 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1701.0
If we take 4 away from 7, we end up with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 4

Let's proceed to step 5:
4 goes into 34 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 17018.0
The remainder is 2 after subtracting 32 from 34.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 4

Moving on to step 6:
When dividing 23 by 4, we get 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 170185.0
Subtracting 20 from 23 leaves us 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.

Advancing to step 7:
If we divide 30 by 4, we get 7 and a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 170185.7
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.

On to step 8:
If we divide 20 by 4, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 170185.75
If we subtract 20 from 20, 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.

Let's proceed to step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 170185.75
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.

Advancing to step 10:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 170185.75
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 final result is 170185.75 with a remainder of 0.0.
