71387217 divided by 140 
The aim is to understand the frequency of 140 in 71387217.

Going ahead to step 1:
140 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 140

On to step 2:
The number 140 fits into 71 0 times, leaving a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Take the next digit (3) from the dividend and append it to 71, then repeat: 713 / 140

Moving on to step 3:
If we divide 713 by 140, we get 5 and a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 700 from 713, we get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 140

Advancing to step 4:
140 can be fit into 138 0 times, resulting in a remainder of 138.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Subtract 0 from 138 to get 138.
Grab the next digit (7) from the dividend, add it to 138, then carry on: 1387 / 140

Advancing to step 5:
140 goes into 1387 9 times with a remainder of 127.
The number 9 becomes the next digit in our result. 
Result so far: 509.0
Subtract 1260 from 1387 to get 127.
Bring next digit (2) of the dividend behind the 127 and repeat the process: 1272 / 140

Moving on to step 6:
The number 140 fits into 1272 9 times, leaving a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 5099.0
The remainder is 12 after subtracting 1260 from 1272.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 140

Moving on to step 7:
140 can be fit into 121 0 times, resulting in a remainder of 121.
Write down 0 as next digit of the result. 
Result so far: 50990.0
The remainder is 121 after subtracting 0 from 121.
Include the next digit (7) from the dividend after 121, then repeat: 1217 / 140

Going ahead to step 8:
1217 divided by 140 is 8 with a remainder of 97.
Write down 8 as next digit of the result. 
Result so far: 509908.0
Deduct 1120 from 1217 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

On to step 9:
140 goes into 970 6 times with a remainder of 130.
The number 6 becomes the next digit in our result. 
Result so far: 509908.6
Subtract 840 from 970 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.

Let's proceed to step 10:
140 can be fit into 1300 9 times, resulting in a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 509908.69
Subtracting 1260 from 1300 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.

Step 11:
When dividing 400 by 140, we get 2 with a remainder of 120.
The number 2 becomes the next digit in our result. 
Result so far: 509908.692
Subtract 280 from 400 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 12:
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: 509908.6928
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.

Step 13:
The number 140 fits into 800 5 times, leaving a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 509908.69285
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.

Going ahead to step 14:
140 can be fit into 1000 7 times, resulting in a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 509908.692857
If we subtract 980 from 1000, we 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.

Advancing to step 15:
When dividing 200 by 140, we get 1 with a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 509908.6928571
If we take 140 away from 200, we end up 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 16:
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: 509908.69285714
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.

In conclusion, the division gives 509908.69285714 with a balance of 4e-08.
