603651 divided by 66 
We're looking to find how many times 66 goes into 603651.

Step 1:
6 divided by 66 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 66

Step 2:
66 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 66

Let's proceed to step 3:
When dividing 603 by 66, we get 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 594 from 603, we get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 66

Advancing to step 4:
66 goes into 96 1 times with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 91.0
Subtracting 66 from 96 leaves us with 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 66

Advancing to step 5:
66 goes into 305 4 times with a remainder of 41.
Put 4 as the next digit of the answer. 
Result so far: 914.0
The remainder is 41 after subtracting 264 from 305.
Grab the next digit (1) from the dividend, add it to 41, then carry on: 411 / 66

On to step 6:
66 goes into 411 6 times with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 9146.0
If we subtract 396 from 411, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
66 can be fit into 150 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 9146.2
If we subtract 132 from 150, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
180 divided by 66 is 2 with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 9146.22
Deduct 132 from 180 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

In conclusion, the division gives 9146.22 with a balance of 0.048.
