20494717 ÷ 140 
We want to divide 20494717 by 140.

On to step 1:
If we divide 2 by 140, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 140

On to step 2:
When dividing 20 by 140, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 140

Step 3:
When dividing 204 by 140, we get 1 with a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 64 after subtracting 140 from 204.
Include the next digit (9) from the dividend after 64, then repeat: 649 / 140

Advancing to step 4:
When dividing 649 by 140, we get 4 with a remainder of 89.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 560 from 649 leaves us with 89.
Take the next digit (4) from the dividend and append it to 89, then repeat: 894 / 140

Going ahead to step 5:
140 goes into 894 6 times with a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 146.0
Deduct 840 from 894 and we're left with 54.
Include the next digit (7) from the dividend after 54, then repeat: 547 / 140

Step 6:
140 goes into 547 3 times with a remainder of 127.
Write down 3 as next digit of the result. 
Result so far: 1463.0
If we subtract 420 from 547, we get 127.
Fetch the next digit (1) from the dividend, attach it to 127 and continue: 1271 / 140

Advancing to step 7:
When dividing 1271 by 140, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 14639.0
Subtract 1260 from 1271 to get 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 140

Moving on to step 8:
140 can be fit into 117 0 times, resulting in a remainder of 117.
The next digit of our result is 0. 
Result so far: 146390.0
Deduct 0 from 117 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 9:
The number 140 fits into 1170 8 times, leaving a remainder of 50.
The next digit of our result is 8. 
Result so far: 146390.8
The remainder is 50 after subtracting 1120 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
500 divided by 140 is 3 with a remainder of 80.
The next digit of our result is 3. 
Result so far: 146390.83
Deduct 420 from 500 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
800 divided by 140 is 5 with a remainder of 100.
The next digit of our result is 5. 
Result so far: 146390.835
Subtract 700 from 800 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 12:
The number 140 fits into 1000 7 times, leaving a remainder of 20.
The next digit of our result is 7. 
Result so far: 146390.8357
Subtract 980 from 1000 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
200 divided by 140 is 1 with a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 146390.83571
Subtracting 140 from 200 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
If we divide 600 by 140, we get 4 and a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 146390.835714
If we take 560 away from 600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 15:
140 can be fit into 400 2 times, resulting in a remainder of 120.
The number 2 becomes the next digit in our result. 
Result so far: 146390.8357142
Deduct 280 from 400 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 16:
The number 140 fits into 1200 8 times, leaving a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 146390.83571428
Subtracting 1120 from 1200 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 146390.83571428 and a remainder of 8e-08.
