We look at the division of 31511780 by 19 
We want to divide 31511780 by 19.

On to step 1:
The number 19 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 19

Let's proceed to step 2:
31 divided by 19 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 19 from 31 to get 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 19

Going ahead to step 3:
The number 19 fits into 125 6 times, leaving a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 114 from 125 leaves us with 11.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 19

Advancing to step 4:
19 goes into 111 5 times with a remainder of 16.
The next digit of our result is 5. 
Result so far: 165.0
Deduct 95 from 111 and we're left with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 19

Step 5:
161 divided by 19 is 8 with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 1658.0
If we take 152 away from 161, we end up with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 19

Let's proceed to step 6:
If we divide 97 by 19, we get 5 and a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 16585.0
Subtract 95 from 97 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 19

Advancing to step 7:
When dividing 28 by 19, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 165851.0
Deduct 19 from 28 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 19

Advancing to step 8:
19 can be fit into 90 4 times, resulting in a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 1658514.0
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 9:
If we divide 140 by 19, we get 7 and a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 1658514.7
Subtracting 133 from 140 leaves us 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 10:
19 can be fit into 70 3 times, resulting in a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 1658514.73
Subtract 57 from 70 to 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.

Let's proceed to step 11:
The number 19 fits into 130 6 times, leaving a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 1658514.736
The remainder is 16 after subtracting 114 from 130.
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 12:
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: 1658514.7368
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 13:
The number 19 fits into 80 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 1658514.73684
Deduct 76 from 80 and we're left 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 14:
19 can be fit into 40 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 1658514.736842
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 15:
The number 19 fits into 20 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1658514.7368421
Subtracting 19 from 20 leaves us 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.

Let's proceed to step 16:
When dividing 10 by 19, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 1658514.7368421
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.

The final result is 1658514.7368421 with a remainder of 1e-08.
