6658650 ÷ 394 
We want to figure out the number of times 6658650 can be divided by 394.

Going ahead to step 1:
394 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 394

Advancing to step 2:
If we divide 66 by 394, we get 0 and a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Take the next digit (5) from the dividend and append it to 66, then repeat: 665 / 394

Going ahead to step 3:
If we divide 665 by 394, we get 1 and a remainder of 271.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 394 from 665 to get 271.
Take the next digit (8) from the dividend and append it to 271, then repeat: 2718 / 394

Step 4:
When dividing 2718 by 394, we get 6 with a remainder of 354.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 2364 from 2718 to get 354.
Append the next digit (6) from the dividend to 354 and continue with: 3546 / 394

On to step 5:
394 goes into 3546 9 times with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 169.0
Subtract 3546 from 3546 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 394

Step 6:
5 divided by 394 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 1690.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 394

On to step 7:
394 can be fit into 50 0 times, resulting in a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 16900.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
500 divided by 394 is 1 with a remainder of 106.
Use 1 as the next digit of our solution. 
Result so far: 16900.1
If we take 394 away from 500, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 9:
The number 394 fits into 1060 2 times, leaving a remainder of 272.
The number 2 becomes the next digit in our result. 
Result so far: 16900.12
If we take 788 away from 1060, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 10:
The number 394 fits into 2720 6 times, leaving a remainder of 356.
Record the quotient 6 as the next digit in the result. 
Result so far: 16900.126
If we take 2364 away from 2720, we end up 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 11:
3560 divided by 394 is 9 with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 16900.1269
Subtracting 3546 from 3560 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
When dividing 140 by 394, we get 0 with a remainder of 140.
The next digit of our result is 0. 
Result so far: 16900.1269
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 13:
If we divide 1400 by 394, we get 3 and a remainder of 218.
The next digit of our result is 3. 
Result so far: 16900.126903
If we subtract 1182 from 1400, we 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.

Advancing to step 14:
2180 divided by 394 is 5 with a remainder of 210.
Record the quotient 5 as the next digit in the result. 
Result so far: 16900.1269035
The remainder is 210 after subtracting 1970 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 15:
When dividing 2100 by 394, we get 5 with a remainder of 130.
The next digit of our result is 5. 
Result so far: 16900.12690355
Subtract 1970 from 2100 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Our division results in 16900.12690355 with a remaining 1.3e-07.
