We divide 66766430 by 392
Let's see how many times 392 fits into 66766430.

Advancing to step 1:
The number 392 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 392

Moving on to step 2:
The number 392 fits into 66 0 times, leaving a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Fetch the next digit (7) from the dividend, attach it to 66 and continue: 667 / 392

Going ahead to step 3:
667 divided by 392 is 1 with a remainder of 275.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 392 from 667, we get 275.
Append the next digit (6) from the dividend to 275 and continue with: 2756 / 392

Let's proceed to step 4:
The number 392 fits into 2756 7 times, leaving a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 17.0
The remainder is 12 after subtracting 2744 from 2756.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 392

Let's proceed to step 5:
When dividing 126 by 392, we get 0 with a remainder of 126.
The number 0 becomes the next digit in our result. 
Result so far: 170.0
If we subtract 0 from 126, we get 126.
Take the next digit (4) from the dividend and append it to 126, then repeat: 1264 / 392

Going ahead to step 6:
392 goes into 1264 3 times with a remainder of 88.
Put 3 as the next digit of the answer. 
Result so far: 1703.0
Subtract 1176 from 1264 to get 88.
Grab the next digit (3) from the dividend, add it to 88, then carry on: 883 / 392

On to step 7:
883 divided by 392 is 2 with a remainder of 99.
Put 2 as the next digit of the answer. 
Result so far: 17032.0
Subtracting 784 from 883 leaves us with 99.
Include the next digit (0) from the dividend after 99, then repeat: 990 / 392

Advancing to step 8:
When dividing 990 by 392, we get 2 with a remainder of 206.
Write down 2 as next digit of the result. 
Result so far: 170322.0
If we subtract 784 from 990, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Going ahead to step 9:
392 can be fit into 2060 5 times, resulting in a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 170322.5
Subtract 1960 from 2060 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 10:
392 can be fit into 1000 2 times, resulting in a remainder of 216.
Use 2 as the next digit of our solution. 
Result so far: 170322.52
Deduct 784 from 1000 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 11:
If we divide 2160 by 392, we get 5 and a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 170322.525
The remainder is 200 after subtracting 1960 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 12:
392 can be fit into 2000 5 times, resulting in a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 170322.5255
If we take 1960 away from 2000, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 170322.5255 with a balance of 0.0004.
