We're dividing 335645 by 70 
The aim is to understand the frequency of 70 in 335645.

Step 1:
When dividing 3 by 70, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 70

Going ahead to step 2:
If we divide 33 by 70, we get 0 and a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Take the next digit (5) from the dividend and append it to 33, then repeat: 335 / 70

Advancing to step 3:
The number 70 fits into 335 4 times, leaving a remainder of 55.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 280 from 335, we get 55.
Append the next digit (6) from the dividend to 55 and continue with: 556 / 70

Moving on to step 4:
70 goes into 556 7 times with a remainder of 66.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Subtract 490 from 556 to get 66.
Append the next digit (4) from the dividend to 66 and continue with: 664 / 70

Step 5:
When dividing 664 by 70, we get 9 with a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 479.0
Deduct 630 from 664 and we're left with 34.
Grab the next digit (5) from the dividend, add it to 34, then carry on: 345 / 70

On to step 6:
If we divide 345 by 70, we get 4 and a remainder of 65.
Put 4 as the next digit of the answer. 
Result so far: 4794.0
Subtracting 280 from 345 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 7:
When dividing 650 by 70, we get 9 with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 4794.9
Deduct 630 from 650 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
70 goes into 200 2 times with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 4794.92
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.

Moving on to step 9:
When dividing 600 by 70, we get 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 4794.928
The remainder is 40 after subtracting 560 from 600.
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 10:
70 can be fit into 400 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 4794.9285
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.

Step 11:
If we divide 500 by 70, we get 7 and a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 4794.92857
Subtract 490 from 500 to get 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 12:
If we divide 100 by 70, we get 1 and a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 4794.928571
If we subtract 70 from 100, we 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.

Going ahead to step 13:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 4794.9285714
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 14:
The number 70 fits into 200 2 times, leaving a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 4794.92857142
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.

The quotient of the division is 4794.92857142, and the remainder is 6e-08.
