530438 divided by 70 
The aim is to understand the frequency of 70 in 530438.

Step 1:
If we divide 5 by 70, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 70

Going ahead to step 2:
70 can be fit into 53 0 times, resulting in a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Fetch the next digit (0) from the dividend, attach it to 53 and continue: 530 / 70

Going ahead to step 3:
If we divide 530 by 70, we get 7 and a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 490 from 530 and we're left with 40.
Bring next digit (4) of the dividend behind the 40 and repeat the process: 404 / 70

Going ahead to step 4:
70 goes into 404 5 times with a remainder of 54.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we subtract 350 from 404, we get 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 70

Step 5:
The number 70 fits into 543 7 times, leaving a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 757.0
If we take 490 away from 543, we end up with 53.
Grab the next digit (8) from the dividend, add it to 53, then carry on: 538 / 70

Advancing to step 6:
When dividing 538 by 70, we get 7 with a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 7577.0
If we take 490 away from 538, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 7:
480 divided by 70 is 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 7577.6
Subtract 420 from 480 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.

Going ahead to step 8:
600 divided by 70 is 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 7577.68
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.

Advancing to step 9:
The number 70 fits into 400 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 7577.685
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.

Let's proceed to step 10:
If we divide 500 by 70, we get 7 and a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 7577.6857
Subtract 490 from 500 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 7577.68571
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.

Let's proceed to step 12:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 7577.685714
The remainder is 20 after subtracting 280 from 300.
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 13:
If we divide 200 by 70, we get 2 and a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 7577.6857142
If we subtract 140 from 200, we 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.

Step 14:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 7577.68571428
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.

Our division results in 7577.68571428 with a remaining 4e-08.
