Let's divide 21080183 by 140
Let's see how many times 140 fits into 21080183.

On to step 1:
2 divided by 140 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 140

Let's proceed to step 2:
140 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 140

Going ahead to step 3:
The number 140 fits into 210 1 times, leaving a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 140 from 210 and we're left with 70.
Take the next digit (8) from the dividend and append it to 70, then repeat: 708 / 140

Going ahead to step 4:
The number 140 fits into 708 5 times, leaving a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 700 from 708 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 140

Step 5:
140 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 150.0
If we subtract 0 from 80, we get 80.
Bring next digit (1) of the dividend behind the 80 and repeat the process: 801 / 140

Let's proceed to step 6:
801 divided by 140 is 5 with a remainder of 101.
Put 5 as the next digit of the answer. 
Result so far: 1505.0
If we subtract 700 from 801, we get 101.
Include the next digit (8) from the dividend after 101, then repeat: 1018 / 140

On to step 7:
The number 140 fits into 1018 7 times, leaving a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 15057.0
Subtracting 980 from 1018 leaves us with 38.
Fetch the next digit (3) from the dividend, attach it to 38 and continue: 383 / 140

Step 8:
140 can be fit into 383 2 times, resulting in a remainder of 103.
Use 2 as the next digit of our solution. 
Result so far: 150572.0
If we subtract 280 from 383, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 9:
140 can be fit into 1030 7 times, resulting in a remainder of 50.
The next digit of our result is 7. 
Result so far: 150572.7
Deduct 980 from 1030 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
If we divide 500 by 140, we get 3 and a remainder of 80.
The next digit of our result is 3. 
Result so far: 150572.73
If we take 420 away from 500, we end up 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.

On to step 11:
When dividing 800 by 140, we get 5 with a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 150572.735
Subtracting 700 from 800 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 12:
140 can be fit into 1000 7 times, resulting in a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 150572.7357
Deduct 980 from 1000 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
140 can be fit into 200 1 times, resulting in a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 150572.73571
Deduct 140 from 200 and we're left 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.

Moving on to step 14:
140 can be fit into 600 4 times, resulting in a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 150572.735714
Subtracting 560 from 600 leaves us 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.

Going ahead to step 15:
140 goes into 400 2 times with a remainder of 120.
The number 2 becomes the next digit in our result. 
Result so far: 150572.7357142
Subtracting 280 from 400 leaves us 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:
1200 divided by 140 is 8 with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 150572.73571428
Deduct 1120 from 1200 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.

The final result is 150572.73571428 with a remainder of 8e-08.
