19451286 ÷ 109 
Our goal is to divide 19451286 by 109.

Let's proceed to step 1:
109 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 109

Step 2:
If we divide 19 by 109, we get 0 and a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 109

Step 3:
When dividing 194 by 109, we get 1 with a remainder of 85.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 109 from 194, we get 85.
Fetch the next digit (5) from the dividend, attach it to 85 and continue: 855 / 109

Step 4:
When dividing 855 by 109, we get 7 with a remainder of 92.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 763 away from 855, we end up with 92.
Include the next digit (1) from the dividend after 92, then repeat: 921 / 109

Step 5:
109 goes into 921 8 times with a remainder of 49.
Record the quotient 8 as the next digit in the result. 
Result so far: 178.0
If we subtract 872 from 921, we get 49.
Bring next digit (2) of the dividend behind the 49 and repeat the process: 492 / 109

Advancing to step 6:
109 can be fit into 492 4 times, resulting in a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 1784.0
Subtract 436 from 492 to get 56.
Append the next digit (8) from the dividend to 56 and continue with: 568 / 109

Advancing to step 7:
When dividing 568 by 109, we get 5 with a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 17845.0
The remainder is 23 after subtracting 545 from 568.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 109

Advancing to step 8:
When dividing 236 by 109, we get 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 178452.0
Deduct 218 from 236 and we're left 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.

Going ahead to step 9:
109 goes into 180 1 times with a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 178452.1
Deduct 109 from 180 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 10:
If we divide 710 by 109, we get 6 and a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 178452.16
The remainder is 56 after subtracting 654 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
If we divide 560 by 109, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 178452.165
Subtract 545 from 560 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
150 divided by 109 is 1 with a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 178452.1651
The remainder is 41 after subtracting 109 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 13:
109 goes into 410 3 times with a remainder of 83.
The next digit of our result is 3. 
Result so far: 178452.16513
If we take 327 away from 410, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 14:
109 can be fit into 830 7 times, resulting in a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 178452.165137
Deduct 763 from 830 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 15:
If we divide 670 by 109, we get 6 and a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 178452.1651376
Subtracting 654 from 670 leaves us 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 16:
If we divide 160 by 109, we get 1 and a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 178452.16513761
If we take 109 away from 160, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

After the division, we end up with 178452.16513761 and a remainder of 5.1e-08.
