We look at the division of 750550 by 70 
The aim is to understand the frequency of 70 in 750550.

On to step 1:
7 divided by 70 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 70

Advancing to step 2:
If we divide 75 by 70, we get 1 and a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 5 after subtracting 70 from 75.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 70

Let's proceed to step 3:
The number 70 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 50 after subtracting 0 from 50.
Include the next digit (5) from the dividend after 50, then repeat: 505 / 70

Moving on to step 4:
The number 70 fits into 505 7 times, leaving a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
If we subtract 490 from 505, we get 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 70

Going ahead to step 5:
When dividing 155 by 70, we get 2 with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 1072.0
Subtract 140 from 155 to get 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 70

Moving on to step 6:
70 can be fit into 150 2 times, resulting in a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 10722.0
Subtract 140 from 150 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.

Moving on to step 7:
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: 10722.1
Subtract 70 from 100 to 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.

On to step 8:
If we divide 300 by 70, we get 4 and a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 10722.14
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.

Step 9:
When dividing 200 by 70, we get 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 10722.142
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.

Let's proceed to step 10:
When dividing 600 by 70, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 10722.1428
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 11:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 10722.14285
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.

Moving on to step 12:
If we divide 500 by 70, we get 7 and a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 10722.142857
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.

On to step 13:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 10722.1428571
Subtract 70 from 100 to 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.

Advancing to step 14:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 10722.14285714
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.

After the division, we end up with 10722.14285714 and a remainder of 2e-08.
