68248651 ÷ 140 
The aim is to understand the frequency of 140 in 68248651.

Let's proceed to step 1:
140 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 140

Step 2:
140 goes into 68 0 times with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Grab the next digit (2) from the dividend, add it to 68, then carry on: 682 / 140

On to step 3:
140 can be fit into 682 4 times, resulting in a remainder of 122.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 560 from 682 and we're left with 122.
Append the next digit (4) from the dividend to 122 and continue with: 1224 / 140

Moving on to step 4:
When dividing 1224 by 140, we get 8 with a remainder of 104.
The next digit of our result is 8. 
Result so far: 48.0
The remainder is 104 after subtracting 1120 from 1224.
Append the next digit (8) from the dividend to 104 and continue with: 1048 / 140

On to step 5:
The number 140 fits into 1048 7 times, leaving a remainder of 68.
Use 7 as the next digit of our solution. 
Result so far: 487.0
If we take 980 away from 1048, we end up with 68.
Grab the next digit (6) from the dividend, add it to 68, then carry on: 686 / 140

On to step 6:
The number 140 fits into 686 4 times, leaving a remainder of 126.
Use 4 as the next digit of our solution. 
Result so far: 4874.0
The remainder is 126 after subtracting 560 from 686.
Append the next digit (5) from the dividend to 126 and continue with: 1265 / 140

On to step 7:
The number 140 fits into 1265 9 times, leaving a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 48749.0
Subtracting 1260 from 1265 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 140

Going ahead to step 8:
140 can be fit into 51 0 times, resulting in a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 487490.0
Deduct 0 from 51 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 9:
If we divide 510 by 140, we get 3 and a remainder of 90.
Use 3 as the next digit of our solution. 
Result so far: 487490.3
If we subtract 420 from 510, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
900 divided by 140 is 6 with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 487490.36
The remainder is 60 after subtracting 840 from 900.
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 11:
The number 140 fits into 600 4 times, leaving a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 487490.364
Deduct 560 from 600 and we're left 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 12:
When dividing 400 by 140, we get 2 with a remainder of 120.
Record the quotient 2 as the next digit in the result. 
Result so far: 487490.3642
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.

Moving on to step 13:
When dividing 1200 by 140, we get 8 with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 487490.36428
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.

Step 14:
800 divided by 140 is 5 with a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 487490.364285
The remainder is 100 after subtracting 700 from 800.
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 15:
The number 140 fits into 1000 7 times, leaving a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 487490.3642857
The remainder is 20 after subtracting 980 from 1000.
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 16:
200 divided by 140 is 1 with a remainder of 60.
The next digit of our result is 1. 
Result so far: 487490.36428571
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.

After the division, we end up with 487490.36428571 and a remainder of 6e-08.
