We're dividing 304180 by 70 
The aim is to understand the frequency of 70 in 304180.

On to step 1:
When dividing 3 by 70, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 70

Let's proceed to step 2:
30 divided by 70 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 70

Advancing to step 3:
70 goes into 304 4 times with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 280 from 304 and we're left with 24.
Take the next digit (1) from the dividend and append it to 24, then repeat: 241 / 70

Step 4:
The number 70 fits into 241 3 times, leaving a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 43.0
The remainder is 31 after subtracting 210 from 241.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 70

Going ahead to step 5:
The number 70 fits into 318 4 times, leaving a remainder of 38.
The next digit of our result is 4. 
Result so far: 434.0
If we take 280 away from 318, we end up with 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 70

Advancing to step 6:
70 goes into 380 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 4345.0
Deduct 350 from 380 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.

Advancing to step 7:
70 goes into 300 4 times with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 4345.4
If we take 280 away from 300, we end up 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.

On to step 8:
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: 4345.42
The remainder is 60 after subtracting 140 from 200.
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:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 4345.428
Deduct 560 from 600 and we're left 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.

Step 10:
70 goes into 400 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 4345.4285
If we subtract 350 from 400, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
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: 4345.42857
If we take 490 away from 500, we end up 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.

Let's proceed to step 12:
When dividing 100 by 70, we get 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 4345.428571
The remainder is 30 after subtracting 70 from 100.
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 13:
70 goes into 300 4 times with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 4345.4285714
Subtract 280 from 300 to 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.

Advancing to step 14:
70 goes into 200 2 times with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 4345.42857142
Subtract 140 from 200 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.

Our division results in 4345.42857142 with a remaining 6e-08.
