We divide 138290 by 70
The aim is to understand the frequency of 70 in 138290.

Moving on to step 1:
If we divide 1 by 70, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 70

Step 2:
70 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 70

On to step 3:
138 divided by 70 is 1 with a remainder of 68.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 70 from 138 to get 68.
Include the next digit (2) from the dividend after 68, then repeat: 682 / 70

Going ahead to step 4:
70 goes into 682 9 times with a remainder of 52.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 52 after subtracting 630 from 682.
Take the next digit (9) from the dividend and append it to 52, then repeat: 529 / 70

Going ahead to step 5:
If we divide 529 by 70, we get 7 and a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 197.0
If we subtract 490 from 529, we get 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 70

Step 6:
70 can be fit into 390 5 times, resulting in a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 1975.0
If we take 350 away from 390, 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.

Let's proceed to step 7:
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: 1975.5
Deduct 350 from 400 and we're left 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.

Let's proceed to step 8:
The number 70 fits into 500 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 1975.57
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.

Going ahead to step 9:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1975.571
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.

Step 10:
300 divided by 70 is 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 1975.5714
If we subtract 280 from 300, 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.

Moving on to step 11:
When dividing 200 by 70, we get 2 with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 1975.57142
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.

On to step 12:
600 divided by 70 is 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 1975.571428
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.

Going ahead to step 13:
400 divided by 70 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1975.5714285
Deduct 350 from 400 and we're left 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.

Advancing to step 14:
When dividing 500 by 70, we get 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 1975.57142857
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 1975.57142857 with a balance of 1e-08.
