143459 divided by 19 
We want to divide 143459 by 19.

Going ahead to step 1:
If we divide 1 by 19, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 19

On to step 2:
19 can be fit into 14 0 times, resulting in a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 19

Step 3:
143 divided by 19 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 133 away from 143, we end up with 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 19

Step 4:
When dividing 104 by 19, we get 5 with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
If we take 95 away from 104, we end up with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 19

On to step 5:
The number 19 fits into 95 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 755.0
Deduct 95 from 95 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 19

Advancing to step 6:
The number 19 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 7550.0
Deduct 0 from 9 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
90 divided by 19 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 7550.4
If we subtract 76 from 90, we 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:
140 divided by 19 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 7550.47
If we subtract 133 from 140, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
When dividing 70 by 19, we get 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 7550.473
If we take 57 away from 70, we end up 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.

Step 10:
130 divided by 19 is 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 7550.4736
Deduct 114 from 130 and we're left 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.

Advancing to step 11:
19 can be fit into 160 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 7550.47368
Deduct 152 from 160 and we're left 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:
The number 19 fits into 80 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 7550.473684
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.

Step 13:
If we divide 40 by 19, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 7550.4736842
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.

Moving on to step 14:
19 goes into 20 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 7550.47368421
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.

After the division, we end up with 7550.47368421 and a remainder of 1e-09.
