Let's divide 21356763 by 140
The aim is to understand the frequency of 140 in 21356763.

Advancing to step 1:
When dividing 2 by 140, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 140

Step 2:
21 divided by 140 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 140

On to step 3:
If we divide 213 by 140, we get 1 and a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 140 from 213 to get 73.
Grab the next digit (5) from the dividend, add it to 73, then carry on: 735 / 140

Going ahead to step 4:
735 divided by 140 is 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 700 away from 735, we end up with 35.
Append the next digit (6) from the dividend to 35 and continue with: 356 / 140

Let's proceed to step 5:
140 can be fit into 356 2 times, resulting in a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 152.0
If we subtract 280 from 356, we get 76.
Grab the next digit (7) from the dividend, add it to 76, then carry on: 767 / 140

Advancing to step 6:
140 goes into 767 5 times with a remainder of 67.
Write down 5 as next digit of the result. 
Result so far: 1525.0
If we take 700 away from 767, we end up with 67.
Fetch the next digit (6) from the dividend, attach it to 67 and continue: 676 / 140

On to step 7:
676 divided by 140 is 4 with a remainder of 116.
Record the quotient 4 as the next digit in the result. 
Result so far: 15254.0
The remainder is 116 after subtracting 560 from 676.
Include the next digit (3) from the dividend after 116, then repeat: 1163 / 140

On to step 8:
When dividing 1163 by 140, we get 8 with a remainder of 43.
Put 8 as the next digit of the answer. 
Result so far: 152548.0
The remainder is 43 after subtracting 1120 from 1163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 9:
If we divide 430 by 140, we get 3 and a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 152548.3
Subtracting 420 from 430 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
100 divided by 140 is 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 152548.3
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 11:
140 can be fit into 1000 7 times, resulting in a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 152548.307
If we take 980 away from 1000, we end up 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 12:
If we divide 200 by 140, we get 1 and a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 152548.3071
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.

Let's proceed to step 13:
140 goes into 600 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 152548.30714
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.

Step 14:
400 divided by 140 is 2 with a remainder of 120.
Use 2 as the next digit of our solution. 
Result so far: 152548.307142
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.

Going ahead to step 15:
When dividing 1200 by 140, we get 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 152548.3071428
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.

Moving on to step 16:
800 divided by 140 is 5 with a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 152548.30714285
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.

After the division, we end up with 152548.30714285 and a remainder of 1e-07.
