21574020 ÷ 140 
We want to figure out the number of times 21574020 can be divided by 140.

Let's proceed to step 1:
2 divided by 140 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 140

Let's proceed to step 2:
When dividing 21 by 140, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 140

Let's proceed to step 3:
The number 140 fits into 215 1 times, leaving a remainder of 75.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 140 from 215 leaves us with 75.
Fetch the next digit (7) from the dividend, attach it to 75 and continue: 757 / 140

Let's proceed to step 4:
140 can be fit into 757 5 times, resulting in a remainder of 57.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 700 from 757 and we're left with 57.
Bring next digit (4) of the dividend behind the 57 and repeat the process: 574 / 140

Going ahead to step 5:
When dividing 574 by 140, we get 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 154.0
Subtracting 560 from 574 leaves us with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 140

On to step 6:
If we divide 140 by 140, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1541.0
If we take 140 away from 140, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 140

Advancing to step 7:
The number 140 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 15410.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 140

Advancing to step 8:
140 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 154100.0
Subtracting 0 from 20 leaves us 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.

Advancing to step 9:
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: 154100.1
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
600 divided by 140 is 4 with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 154100.14
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.

On to step 11:
The number 140 fits into 400 2 times, leaving a remainder of 120.
Use 2 as the next digit of our solution. 
Result so far: 154100.142
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 12:
140 goes into 1200 8 times with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 154100.1428
If we subtract 1120 from 1200, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
When dividing 800 by 140, we get 5 with a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 154100.14285
If we take 700 away from 800, we end up 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.

On to step 14:
The number 140 fits into 1000 7 times, leaving a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 154100.142857
Subtracting 980 from 1000 leaves us 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.

Going ahead to step 15:
140 goes into 200 1 times with a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 154100.1428571
If we subtract 140 from 200, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 16:
140 can be fit into 600 4 times, resulting in a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 154100.14285714
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 154100.14285714 with a remaining 4e-08.
