142042 divided by 70 
The aim is to understand the frequency of 70 in 142042.

Step 1:
The number 70 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 70

Going ahead to step 2:
14 divided by 70 is 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 70

Let's proceed to step 3:
142 divided by 70 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 2 after subtracting 140 from 142.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 70

Advancing to step 4:
The number 70 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 20 to get 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 70

Let's proceed to step 5:
The number 70 fits into 204 2 times, leaving a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 202.0
Subtract 140 from 204 to get 64.
Grab the next digit (2) from the dividend, add it to 64, then carry on: 642 / 70

Advancing to step 6:
The number 70 fits into 642 9 times, leaving a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 2029.0
Deduct 630 from 642 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
70 goes into 120 1 times with a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 2029.1
If we take 70 away from 120, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
When dividing 500 by 70, we get 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 2029.17
Deduct 490 from 500 and we're left 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.

Let's proceed to step 9:
If we divide 100 by 70, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 2029.171
Subtract 70 from 100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 2029.1714
Subtract 280 from 300 to 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.

Going ahead to step 11:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 2029.17142
Deduct 140 from 200 and we're left 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.

Moving on to step 12:
600 divided by 70 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 2029.171428
If we take 560 away from 600, we end up 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.

Moving on to step 13:
When dividing 400 by 70, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 2029.1714285
If we take 350 away from 400, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
500 divided by 70 is 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 2029.17142857
If we take 490 away from 500, we end up 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.

In conclusion, the division gives 2029.17142857 with a balance of 1e-08.
