490985 divided by 70 
The aim is to understand the frequency of 70 in 490985.

Advancing to step 1:
If we divide 4 by 70, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 70

Moving on to step 2:
49 divided by 70 is 0 with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Grab the next digit (0) from the dividend, add it to 49, then carry on: 490 / 70

Let's proceed to step 3:
If we divide 490 by 70, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 490 away from 490, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 70

Advancing to step 4:
When dividing 9 by 70, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 70.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 70

Going ahead to step 5:
The number 70 fits into 98 1 times, leaving a remainder of 28.
The next digit of our result is 1. 
Result so far: 701.0
If we take 70 away from 98, we end up with 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 70

Advancing to step 6:
70 can be fit into 285 4 times, resulting in a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 7014.0
Deduct 280 from 285 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
70 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 7014.0
Deduct 0 from 50 and we're left 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.

Going ahead to step 8:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 7014.07
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.

Moving on to step 9:
70 goes into 100 1 times with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 7014.071
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.

Step 10:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 7014.0714
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.

Let's proceed to step 11:
When dividing 200 by 70, we get 2 with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 7014.07142
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.

Moving on to step 12:
70 goes into 600 8 times with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 7014.071428
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 13:
If we divide 400 by 70, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 7014.0714285
Subtract 350 from 400 to 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.

Step 14:
70 goes into 500 7 times with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 7014.07142857
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.

Our division results in 7014.07142857 with a remaining 1e-08.
