66099437 divided by 473 
Our goal is to divide 66099437 by 473.

Going ahead to step 1:
6 divided by 473 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 473

Going ahead to step 2:
66 divided by 473 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Bring next digit (0) of the dividend behind the 66 and repeat the process: 660 / 473

Moving on to step 3:
473 goes into 660 1 times with a remainder of 187.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 187 after subtracting 473 from 660.
Fetch the next digit (9) from the dividend, attach it to 187 and continue: 1879 / 473

Let's proceed to step 4:
The number 473 fits into 1879 3 times, leaving a remainder of 460.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 1419 from 1879 to get 460.
Append the next digit (9) from the dividend to 460 and continue with: 4609 / 473

Going ahead to step 5:
The number 473 fits into 4609 9 times, leaving a remainder of 352.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
Subtracting 4257 from 4609 leaves us with 352.
Bring next digit (4) of the dividend behind the 352 and repeat the process: 3524 / 473

Let's proceed to step 6:
3524 divided by 473 is 7 with a remainder of 213.
The next digit of our result is 7. 
Result so far: 1397.0
Subtracting 3311 from 3524 leaves us with 213.
Take the next digit (3) from the dividend and append it to 213, then repeat: 2133 / 473

Step 7:
2133 divided by 473 is 4 with a remainder of 241.
The number 4 becomes the next digit in our result. 
Result so far: 13974.0
Subtract 1892 from 2133 to get 241.
Include the next digit (7) from the dividend after 241, then repeat: 2417 / 473

Going ahead to step 8:
When dividing 2417 by 473, we get 5 with a remainder of 52.
Use 5 as the next digit of our solution. 
Result so far: 139745.0
Subtracting 2365 from 2417 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
If we divide 520 by 473, we get 1 and a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 139745.1
If we subtract 473 from 520, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 10:
473 goes into 470 0 times with a remainder of 470.
Put 0 as the next digit of the answer. 
Result so far: 139745.1
Subtracting 0 from 470 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 11:
If we divide 4700 by 473, we get 9 and a remainder of 443.
Put 9 as the next digit of the answer. 
Result so far: 139745.109
If we subtract 4257 from 4700, we get 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Moving on to step 12:
473 can be fit into 4430 9 times, resulting in a remainder of 173.
The next digit of our result is 9. 
Result so far: 139745.1099
Subtract 4257 from 4430 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

In conclusion, the division gives 139745.1099 with a balance of 0.00173.
