We look at the division of 669458 by 4 
We want to divide 669458 by 4.

Going ahead to step 1:
6 divided by 4 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 4 from 6, we get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 4

Step 2:
The number 4 fits into 26 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 24 from 26 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 4

Going ahead to step 3:
4 can be fit into 29 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 167.0
The remainder is 1 after subtracting 28 from 29.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 4

Let's proceed to step 4:
If we divide 14 by 4, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 1673.0
The remainder is 2 after subtracting 12 from 14.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 4

Let's proceed to step 5:
4 goes into 25 6 times with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 16736.0
Subtracting 24 from 25 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 4

On to step 6:
If we divide 18 by 4, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 167364.0
If we take 16 away from 18, 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.

Advancing to step 7:
4 goes into 20 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 167364.5
The remainder is 0 after subtracting 20 from 20.
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 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: 167364.5
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.

Going ahead to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 167364.5
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 result is 167364.5 with a remainder of 0.0.
