66400962 ÷ 223 
We want to divide 66400962 by 223.

Step 1:
If we divide 6 by 223, we get 0 and 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.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 223

On to step 2:
The number 223 fits into 66 0 times, leaving a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (4) from the dividend and append it to 66, then repeat: 664 / 223

On to step 3:
223 can be fit into 664 2 times, resulting in a remainder of 218.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 446 from 664 and we're left with 218.
Grab the next digit (0) from the dividend, add it to 218, then carry on: 2180 / 223

Let's proceed to step 4:
If we divide 2180 by 223, we get 9 and a remainder of 173.
The next digit of our result is 9. 
Result so far: 29.0
If we subtract 2007 from 2180, we get 173.
Fetch the next digit (0) from the dividend, attach it to 173 and continue: 1730 / 223

Let's proceed to step 5:
1730 divided by 223 is 7 with a remainder of 169.
Use 7 as the next digit of our solution. 
Result so far: 297.0
Subtracting 1561 from 1730 leaves us with 169.
Bring next digit (9) of the dividend behind the 169 and repeat the process: 1699 / 223

Let's proceed to step 6:
223 goes into 1699 7 times with a remainder of 138.
Put 7 as the next digit of the answer. 
Result so far: 2977.0
Subtract 1561 from 1699 to get 138.
Fetch the next digit (6) from the dividend, attach it to 138 and continue: 1386 / 223

Going ahead to step 7:
When dividing 1386 by 223, we get 6 with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 29776.0
Deduct 1338 from 1386 and we're left with 48.
Bring next digit (2) of the dividend behind the 48 and repeat the process: 482 / 223

Let's proceed to step 8:
The number 223 fits into 482 2 times, leaving a remainder of 36.
The next digit of our result is 2. 
Result so far: 297762.0
Deduct 446 from 482 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
The number 223 fits into 360 1 times, leaving a remainder of 137.
Record the quotient 1 as the next digit in the result. 
Result so far: 297762.1
If we subtract 223 from 360, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 10:
If we divide 1370 by 223, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 297762.16
If we subtract 1338 from 1370, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 11:
223 can be fit into 320 1 times, resulting in a remainder of 97.
The next digit of our result is 1. 
Result so far: 297762.161
Subtracting 223 from 320 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 12:
If we divide 970 by 223, we get 4 and a remainder of 78.
The number 4 becomes the next digit in our result. 
Result so far: 297762.1614
Subtracting 892 from 970 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 13:
When dividing 780 by 223, we get 3 with a remainder of 111.
Use 3 as the next digit of our solution. 
Result so far: 297762.16143
Subtract 669 from 780 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 14:
If we divide 1110 by 223, we get 4 and a remainder of 218.
Record the quotient 4 as the next digit in the result. 
Result so far: 297762.161434
Subtract 892 from 1110 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 15:
The number 223 fits into 2180 9 times, leaving a remainder of 173.
The next digit of our result is 9. 
Result so far: 297762.1614349
If we subtract 2007 from 2180, we 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.

Step 16:
223 goes into 1730 7 times with a remainder of 169.
Record the quotient 7 as the next digit in the result. 
Result so far: 297762.16143497
Subtract 1561 from 1730 to get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

In conclusion, the division gives 297762.16143497 with a balance of 1.69e-07.
