We're dividing 271949 by 140 
The aim is to understand the frequency of 140 in 271949.

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
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 140

Going ahead to step 2:
140 goes into 27 0 times with a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 140

Let's proceed to step 3:
140 can be fit into 271 1 times, resulting in a remainder of 131.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 140 away from 271, we end up with 131.
Fetch the next digit (9) from the dividend, attach it to 131 and continue: 1319 / 140

Advancing to step 4:
If we divide 1319 by 140, we get 9 and a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 1260 from 1319 leaves us with 59.
Take the next digit (4) from the dividend and append it to 59, then repeat: 594 / 140

On to step 5:
594 divided by 140 is 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 194.0
If we subtract 560 from 594, we get 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 140

Let's proceed to step 6:
When dividing 349 by 140, we get 2 with a remainder of 69.
Use 2 as the next digit of our solution. 
Result so far: 1942.0
If we subtract 280 from 349, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 7:
The number 140 fits into 690 4 times, leaving a remainder of 130.
Record the quotient 4 as the next digit in the result. 
Result so far: 1942.4
Subtract 560 from 690 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 8:
1300 divided by 140 is 9 with a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 1942.49
The remainder is 40 after subtracting 1260 from 1300.
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 9:
The number 140 fits into 400 2 times, leaving a remainder of 120.
The next digit of our result is 2. 
Result so far: 1942.492
If we take 280 away from 400, we end up 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.

Step 10:
140 can be fit into 1200 8 times, resulting in a remainder of 80.
The next digit of our result is 8. 
Result so far: 1942.4928
If we take 1120 away from 1200, 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.

Advancing to step 11:
140 can be fit into 800 5 times, resulting in a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 1942.49285
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 12:
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: 1942.492857
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.

Step 13:
200 divided by 140 is 1 with a remainder of 60.
Put 1 as the next digit of the answer. 
Result so far: 1942.4928571
Subtract 140 from 200 to 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 14:
140 goes into 600 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 1942.49285714
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 1942.49285714 with a remaining 4e-08.
