660172 divided by 4 
We want to divide 660172 by 4.

Let's proceed to step 1:
6 divided by 4 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 4 from 6 and we're left with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 4

Step 2:
4 goes into 26 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 2 after subtracting 24 from 26.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 4

Advancing to step 3:
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: 165.0
Subtracting 20 from 20 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 4

Going ahead to step 4:
4 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 1650.0
Subtract 0 from 1 to get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 4

Going ahead to step 5:
4 can be fit into 17 4 times, resulting in a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 16504.0
Deduct 16 from 17 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 4

Step 6:
When dividing 12 by 4, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 165043.0
Deduct 12 from 12 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.

Step 7:
0 divided by 4 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 165043.0
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.

Step 8:
When dividing 0 by 4, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 165043.0
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.

In conclusion, the division gives 165043.0 with a balance of 0.0.
