Let's divide 667638 by 70
The aim is to understand the frequency of 70 in 667638.

Moving on to step 1:
When dividing 6 by 70, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 70

Going ahead to step 2:
If we divide 66 by 70, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Fetch the next digit (7) from the dividend, attach it to 66 and continue: 667 / 70

Moving on to step 3:
If we divide 667 by 70, we get 9 and a remainder of 37.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 630 from 667 leaves us with 37.
Grab the next digit (6) from the dividend, add it to 37, then carry on: 376 / 70

On to step 4:
376 divided by 70 is 5 with a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 95.0
Subtract 350 from 376 to get 26.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 70

On to step 5:
70 can be fit into 263 3 times, resulting in a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 953.0
If we subtract 210 from 263, we get 53.
Append the next digit (8) from the dividend to 53 and continue with: 538 / 70

Step 6:
70 can be fit into 538 7 times, resulting in a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 9537.0
If we take 490 away from 538, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 7:
70 can be fit into 480 6 times, resulting in a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 9537.6
Subtract 420 from 480 to 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.

Going ahead to step 8:
When dividing 600 by 70, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 9537.68
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.

On to step 9:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 9537.685
The remainder is 50 after subtracting 350 from 400.
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 10:
500 divided by 70 is 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 9537.6857
The remainder is 10 after subtracting 490 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
If we divide 100 by 70, we get 1 and a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 9537.68571
Subtracting 70 from 100 leaves us 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.

Advancing to step 12:
70 goes into 300 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 9537.685714
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 13:
200 divided by 70 is 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 9537.6857142
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.

On to step 14:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 9537.68571428
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 9537.68571428 with a remainder of 4e-08.
