3351 divided by 19 
We want to figure out the number of times 3351 can be divided by 19.

On to step 1:
19 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 19

Moving on to step 2:
33 divided by 19 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 19 from 33 and we're left with 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 19

On to step 3:
19 goes into 145 7 times with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 133 from 145, we get 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 19

Going ahead to step 4:
The number 19 fits into 121 6 times, leaving a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 176.0
Deduct 114 from 121 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 5:
19 can be fit into 70 3 times, resulting in a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 176.3
Deduct 57 from 70 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.

Advancing to step 6:
130 divided by 19 is 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 176.36
If we subtract 114 from 130, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
The number 19 fits into 160 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 176.368
If we take 152 away from 160, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
If we divide 80 by 19, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 176.3684
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 9:
19 goes into 40 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 176.36842
Deduct 38 from 40 and we're left 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 10:
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: 176.368421
Deduct 19 from 20 and we're left 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.

Moving on to step 11:
10 divided by 19 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 176.368421
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.

Advancing to step 12:
19 goes into 100 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 176.36842105
The remainder is 5 after subtracting 95 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 176.36842105 with a remainder of 5e-09.
