We divide 900230 by 70
The aim is to understand the frequency of 70 in 900230.

Advancing to step 1:
9 divided by 70 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 70

Advancing to step 2:
The number 70 fits into 90 1 times, leaving a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 70 from 90, we get 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 70

On to step 3:
If we divide 200 by 70, we get 2 and a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 140 from 200, we get 60.
Fetch the next digit (2) from the dividend, attach it to 60 and continue: 602 / 70

On to step 4:
70 can be fit into 602 8 times, resulting in a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 128.0
If we subtract 560 from 602, we get 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 70

Let's proceed to step 5:
When dividing 423 by 70, we get 6 with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 1286.0
Deduct 420 from 423 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 70

Going ahead to step 6:
30 divided by 70 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 12860.0
Deduct 0 from 30 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.

Moving on to step 7:
70 goes into 300 4 times with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 12860.4
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 8:
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: 12860.42
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.

Advancing to step 9:
70 goes into 600 8 times with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 12860.428
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.

Moving on to step 10:
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: 12860.4285
If we take 350 away from 400, we end up 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.

Let's proceed to step 11:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 12860.42857
Subtracting 490 from 500 leaves us 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.

Moving on to step 12:
70 goes into 100 1 times with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 12860.428571
Deduct 70 from 100 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.

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: 12860.4285714
Deduct 280 from 300 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 14:
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: 12860.42857142
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.

After the division, we end up with 12860.42857142 and a remainder of 6e-08.
