We look at the division of 394187 by 70 
The aim is to understand the frequency of 70 in 394187.

Going ahead to step 1:
When dividing 3 by 70, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 70

Step 2:
70 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 70

Moving on to step 3:
The number 70 fits into 394 5 times, leaving a remainder of 44.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 350 from 394 and we're left with 44.
Bring next digit (1) of the dividend behind the 44 and repeat the process: 441 / 70

Step 4:
The number 70 fits into 441 6 times, leaving a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 56.0
Deduct 420 from 441 and we're left with 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 70

Moving on to step 5:
The number 70 fits into 218 3 times, leaving a remainder of 8.
The next digit of our result is 3. 
Result so far: 563.0
If we take 210 away from 218, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 70

Moving on to step 6:
The number 70 fits into 87 1 times, leaving a remainder of 17.
The next digit of our result is 1. 
Result so far: 5631.0
If we take 70 away from 87, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
170 divided by 70 is 2 with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 5631.2
The remainder is 30 after subtracting 140 from 170.
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 8:
The number 70 fits into 300 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 5631.24
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.

Let's proceed to step 9:
200 divided by 70 is 2 with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 5631.242
Subtracting 140 from 200 leaves us 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.

Going ahead to step 10:
When dividing 600 by 70, we get 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 5631.2428
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.

Step 11:
If we divide 400 by 70, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 5631.24285
Subtracting 350 from 400 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
70 goes into 500 7 times with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 5631.242857
Deduct 490 from 500 and we're left 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.

Advancing to step 13:
The number 70 fits into 100 1 times, leaving a remainder of 30.
The next digit of our result is 1. 
Result so far: 5631.2428571
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.

Let's proceed to step 14:
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: 5631.24285714
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.

After the division, we end up with 5631.24285714 and a remainder of 2e-08.
