We divide 668509 by 70
The aim is to understand the frequency of 70 in 668509.

Moving on to step 1:
If we divide 6 by 70, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 70

Let's proceed to step 2:
When dividing 66 by 70, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 70

On to step 3:
70 goes into 668 9 times with a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 630 from 668, we get 38.
Grab the next digit (5) from the dividend, add it to 38, then carry on: 385 / 70

Going ahead to step 4:
385 divided by 70 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
If we take 350 away from 385, we end up with 35.
Include the next digit (0) from the dividend after 35, then repeat: 350 / 70

Advancing to step 5:
70 can be fit into 350 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 955.0
Subtract 350 from 350 to get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 70

Advancing to step 6:
70 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 9550.0
The remainder is 9 after subtracting 0 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
90 divided by 70 is 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 9550.1
Subtracting 70 from 90 leaves us 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.

On to step 8:
The number 70 fits into 200 2 times, leaving a remainder of 60.
The next digit of our result is 2. 
Result so far: 9550.12
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.

Moving on to step 9:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 9550.128
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.

Advancing to step 10:
400 divided by 70 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 9550.1285
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.

Step 11:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 9550.12857
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:
The number 70 fits into 100 1 times, leaving a remainder of 30.
The next digit of our result is 1. 
Result so far: 9550.128571
Subtracting 70 from 100 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.

Advancing to step 13:
The number 70 fits into 300 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 9550.1285714
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.

Advancing to step 14:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 9550.12857142
Subtracting 140 from 200 leaves us 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.

The quotient of the division is 9550.12857142, and the remainder is 6e-08.
