12282 ÷ 19 
We're looking to find how many times 19 goes into 12282.

On to step 1:
When dividing 1 by 19, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 19

On to step 2:
If we divide 12 by 19, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 19

Advancing to step 3:
19 goes into 122 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 8 after subtracting 114 from 122.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 19

Going ahead to step 4:
19 can be fit into 88 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 64.0
Subtracting 76 from 88 leaves us with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 19

Advancing to step 5:
19 goes into 122 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 646.0
The remainder is 8 after subtracting 114 from 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 6:
The number 19 fits into 80 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 646.4
If we subtract 76 from 80, 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.

On to step 7:
The number 19 fits into 40 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 646.42
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.

On to step 8:
If we divide 20 by 19, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 646.421
The remainder is 1 after subtracting 19 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
19 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 646.421
Deduct 0 from 10 and we're left 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 10:
19 can be fit into 100 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 646.42105
Deduct 95 from 100 and we're left 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.

Advancing to step 11:
19 goes into 50 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 646.421052
The remainder is 12 after subtracting 38 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
When dividing 120 by 19, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 646.4210526
Deduct 114 from 120 and we're left with 6.
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:
If we divide 60 by 19, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 646.42105263
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.

The final outcome is 646.42105263, with a leftover of 3e-09.
