203864 divided by 70 
The aim is to understand the frequency of 70 in 203864.

On to step 1:
If we divide 2 by 70, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 70

Advancing to step 2:
70 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 70

On to step 3:
203 divided by 70 is 2 with a remainder of 63.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 140 from 203, we get 63.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 70

Moving on to step 4:
70 goes into 638 9 times with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 29.0
Deduct 630 from 638 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 70

On to step 5:
70 can be fit into 86 1 times, resulting in a remainder of 16.
The next digit of our result is 1. 
Result so far: 291.0
If we take 70 away from 86, we end up with 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 70

Going ahead to step 6:
If we divide 164 by 70, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 2912.0
The remainder is 24 after subtracting 140 from 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
When dividing 240 by 70, we get 3 with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 2912.3
Subtracting 210 from 240 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.

Going ahead to step 8:
When dividing 300 by 70, we get 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 2912.34
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.

Step 9:
70 goes into 200 2 times with a remainder of 60.
The next digit of our result is 2. 
Result so far: 2912.342
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 10:
70 goes into 600 8 times with a remainder of 40.
The next digit of our result is 8. 
Result so far: 2912.3428
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.

Let's proceed to step 11:
If we divide 400 by 70, we get 5 and a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 2912.34285
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.

On to step 12:
70 can be fit into 500 7 times, resulting in a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 2912.342857
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.

Going ahead to step 13:
70 goes into 100 1 times with a remainder of 30.
The next digit of our result is 1. 
Result so far: 2912.3428571
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.

Moving on to step 14:
300 divided by 70 is 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 2912.34285714
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.

The final result is 2912.34285714 with a remainder of 2e-08.
