We divide 1388 by 70
The aim is to understand the frequency of 70 in 1388.

Moving on to step 1:
The number 70 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 70

Advancing to step 2:
70 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 70

Let's proceed to step 3:
The number 70 fits into 138 1 times, leaving a remainder of 68.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 70 from 138 leaves us with 68.
Fetch the next digit (8) from the dividend, attach it to 68 and continue: 688 / 70

On to step 4:
When dividing 688 by 70, we get 9 with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 58 after subtracting 630 from 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 5:
70 goes into 580 8 times with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 19.8
The remainder is 20 after subtracting 560 from 580.
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 6:
200 divided by 70 is 2 with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 19.82
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.

Advancing to step 7:
If we divide 600 by 70, we get 8 and a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 19.828
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 8:
The number 70 fits into 400 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 19.8285
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.

Step 9:
70 can be fit into 500 7 times, resulting in a remainder of 10.
The next digit of our result is 7. 
Result so far: 19.82857
Subtracting 490 from 500 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.

Step 10:
100 divided by 70 is 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 19.828571
Deduct 70 from 100 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
If we divide 300 by 70, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 19.8285714
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
If we divide 200 by 70, we get 2 and a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 19.82857142
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.

In conclusion, the division gives 19.82857142 with a balance of 6e-08.
