840007 ÷ 19 
We want to divide 840007 by 19.

Step 1:
8 divided by 19 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 19

Advancing to step 2:
If we divide 84 by 19, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 76 from 84 leaves us with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 19

Going ahead to step 3:
The number 19 fits into 80 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 44.0
If we subtract 76 from 80, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 19

Going ahead to step 4:
If we divide 40 by 19, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 442.0
The remainder is 2 after subtracting 38 from 40.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 19

Let's proceed to step 5:
The number 19 fits into 20 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 4421.0
Deduct 19 from 20 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 19

Going ahead to step 6:
If we divide 17 by 19, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 44210.0
Subtracting 0 from 17 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
The number 19 fits into 170 8 times, leaving a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 44210.8
If we subtract 152 from 170, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
If we divide 180 by 19, we get 9 and a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 44210.89
If we take 171 away from 180, we end up 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.

Step 9:
If we divide 90 by 19, we get 4 and a remainder of 14.
The next digit of our result is 4. 
Result so far: 44210.894
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.

Let's proceed to step 10:
When dividing 140 by 19, we get 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 44210.8947
If we take 133 away from 140, we end up 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.

Step 11:
When dividing 70 by 19, we get 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 44210.89473
Subtracting 57 from 70 leaves us 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.

On to step 12:
19 can be fit into 130 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 44210.894736
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 13:
19 goes into 160 8 times with a remainder of 8.
The next digit of our result is 8. 
Result so far: 44210.8947368
Subtract 152 from 160 to 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.

On to step 14:
80 divided by 19 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 44210.89473684
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 44210.89473684, with a leftover of 4e-09.
