661166 ÷ 19 
We want to figure out the number of times 661166 can be divided by 19.

Step 1:
6 divided by 19 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in 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 / 19

Advancing to step 2:
66 divided by 19 is 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 9 after subtracting 57 from 66.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 19

Step 3:
When dividing 91 by 19, we get 4 with a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtracting 76 from 91 leaves us with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 19

Going ahead to step 4:
19 goes into 151 7 times with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 347.0
The remainder is 18 after subtracting 133 from 151.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 19

Going ahead to step 5:
When dividing 186 by 19, we get 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 3479.0
If we subtract 171 from 186, we get 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 19

Let's proceed to step 6:
156 divided by 19 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 34798.0
If we subtract 152 from 156, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
40 divided by 19 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 34798.2
Subtract 38 from 40 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
When dividing 20 by 19, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 34798.21
If we take 19 away from 20, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
10 divided by 19 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 34798.21
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
When dividing 100 by 19, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 34798.2105
Subtracting 95 from 100 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
19 goes into 50 2 times with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 34798.21052
Subtract 38 from 50 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
The number 19 fits into 120 6 times, leaving a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 34798.210526
The remainder is 6 after subtracting 114 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
19 can be fit into 60 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 34798.2105263
Deduct 57 from 60 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 14:
30 divided by 19 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 34798.21052631
Deduct 19 from 30 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 34798.21052631 with a remaining 1.1e-08.
