66555932 divided by 423 
We're looking to find how many times 423 goes into 66555932.

Let's proceed to step 1:
423 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
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 / 423

Going ahead to step 2:
When dividing 66 by 423, we get 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 423

On to step 3:
The number 423 fits into 665 1 times, leaving a remainder of 242.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 423 away from 665, we end up with 242.
Append the next digit (5) from the dividend to 242 and continue with: 2425 / 423

Step 4:
If we divide 2425 by 423, we get 5 and a remainder of 310.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 2115 from 2425, we get 310.
Grab the next digit (5) from the dividend, add it to 310, then carry on: 3105 / 423

Moving on to step 5:
3105 divided by 423 is 7 with a remainder of 144.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
If we subtract 2961 from 3105, we get 144.
Bring next digit (9) of the dividend behind the 144 and repeat the process: 1449 / 423

On to step 6:
423 can be fit into 1449 3 times, resulting in a remainder of 180.
Write down 3 as next digit of the result. 
Result so far: 1573.0
Deduct 1269 from 1449 and we're left with 180.
Append the next digit (3) from the dividend to 180 and continue with: 1803 / 423

Going ahead to step 7:
1803 divided by 423 is 4 with a remainder of 111.
The next digit of our result is 4. 
Result so far: 15734.0
If we subtract 1692 from 1803, we get 111.
Append the next digit (2) from the dividend to 111 and continue with: 1112 / 423

Moving on to step 8:
When dividing 1112 by 423, we get 2 with a remainder of 266.
Use 2 as the next digit of our solution. 
Result so far: 157342.0
If we take 846 away from 1112, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 9:
423 goes into 2660 6 times with a remainder of 122.
Write down 6 as next digit of the result. 
Result so far: 157342.6
Subtracting 2538 from 2660 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 10:
If we divide 1220 by 423, we get 2 and a remainder of 374.
Record the quotient 2 as the next digit in the result. 
Result so far: 157342.62
Deduct 846 from 1220 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 11:
The number 423 fits into 3740 8 times, leaving a remainder of 356.
The next digit of our result is 8. 
Result so far: 157342.628
Deduct 3384 from 3740 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 12:
423 goes into 3560 8 times with a remainder of 176.
Record the quotient 8 as the next digit in the result. 
Result so far: 157342.6288
If we subtract 3384 from 3560, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

In conclusion, the division gives 157342.6288 with a balance of 0.00176.
