639702 divided by 70 
The aim is to understand the frequency of 70 in 639702.

Going ahead to step 1:
70 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 70

Step 2:
70 goes into 63 0 times with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 70

Let's proceed to step 3:
When dividing 639 by 70, we get 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 630 from 639, we get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 70

Step 4:
70 goes into 97 1 times with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 91.0
Subtract 70 from 97 to get 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 70

On to step 5:
270 divided by 70 is 3 with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 913.0
Subtracting 210 from 270 leaves us with 60.
Append the next digit (2) from the dividend to 60 and continue with: 602 / 70

Step 6:
70 goes into 602 8 times with a remainder of 42.
The next digit of our result is 8. 
Result so far: 9138.0
The remainder is 42 after subtracting 560 from 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
70 can be fit into 420 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 9138.6
The remainder is 0 after subtracting 420 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
70 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9138.6
If we subtract 0 from 0, we 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.

Going ahead to step 9:
70 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9138.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 9138.6, with a leftover of 0.0.
