We're dividing 3646 by 19 
We want to figure out the number of times 3646 can be divided by 19.

Going ahead to step 1:
19 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 19

Step 2:
When dividing 36 by 19, we get 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
If we take 19 away from 36, we end up with 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 19

Advancing to step 3:
If we divide 174 by 19, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 171 from 174 and we're left with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 19

Advancing to step 4:
If we divide 36 by 19, we get 1 and a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 191.0
If we subtract 19 from 36, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 5:
When dividing 170 by 19, we get 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 191.8
If we take 152 away from 170, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 6:
If we divide 180 by 19, we get 9 and a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 191.89
The remainder is 9 after subtracting 171 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
19 can be fit into 90 4 times, resulting in a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 191.894
Subtract 76 from 90 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
If we divide 140 by 19, we get 7 and a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 191.8947
The remainder is 7 after subtracting 133 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
70 divided by 19 is 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 191.89473
If we subtract 57 from 70, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 10:
19 goes into 130 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 191.894736
If we take 114 away from 130, we end up with 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 11:
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: 191.8947368
Subtracting 152 from 160 leaves us 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.

Going ahead to step 12:
If we divide 80 by 19, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 191.89473684
Subtracting 76 from 80 leaves us 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.

The final outcome is 191.89473684, with a leftover of 4e-09.
