Let's divide 137900 by 70
The aim is to understand the frequency of 70 in 137900.

On to 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
Subtract 0 from 1 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 70

Going ahead to step 2:
70 can be fit into 13 0 times, resulting in a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 70

Let's proceed to step 3:
70 goes into 137 1 times with a remainder of 67.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 70 away from 137, we end up with 67.
Include the next digit (9) from the dividend after 67, then repeat: 679 / 70

Step 4:
70 goes into 679 9 times with a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 49 after subtracting 630 from 679.
Include the next digit (0) from the dividend after 49, then repeat: 490 / 70

Step 5:
70 can be fit into 490 7 times, resulting in a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 197.0
The remainder is 0 after subtracting 490 from 490.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 70

Moving on to step 6:
0 divided by 70 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1970.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
The number 70 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1970.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
The number 70 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1970.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 1970.0 with a remaining 0.0.
