661498 ÷ 19 
We want to figure out the number of times 661498 can be divided by 19.

Moving on to step 1:
When dividing 6 by 19, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 19

On to step 2:
19 goes into 66 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 57 from 66, we get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 19

Moving on to step 3:
91 divided by 19 is 4 with a remainder of 15.
The next digit of our result is 4. 
Result so far: 34.0
The remainder is 15 after subtracting 76 from 91.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 19

Let's proceed to step 4:
154 divided by 19 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 348.0
Subtracting 152 from 154 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 19

On to step 5:
If we divide 29 by 19, we get 1 and a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 3481.0
If we subtract 19 from 29, we get 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 19

Step 6:
The number 19 fits into 108 5 times, leaving a remainder of 13.
The next digit of our result is 5. 
Result so far: 34815.0
Deduct 95 from 108 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
130 divided by 19 is 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 34815.6
The remainder is 16 after subtracting 114 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
The number 19 fits into 160 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 34815.68
If we subtract 152 from 160, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
19 can be fit into 80 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 34815.684
If we take 76 away from 80, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
When dividing 40 by 19, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 34815.6842
If we take 38 away from 40, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
19 can be fit into 20 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 34815.68421
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.

Going ahead to step 12:
10 divided by 19 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 34815.68421
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
If we divide 100 by 19, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 34815.6842105
Subtract 95 from 100 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 14:
When dividing 50 by 19, we get 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 34815.68421052
If we take 38 away from 50, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 34815.68421052, with a leftover of 1.2e-08.
