We look at the division of 69213359 by 670 
The aim is to understand the frequency of 670 in 69213359.

On to step 1:
6 divided by 670 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 670

Going ahead to step 2:
670 can be fit into 69 0 times, resulting in a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Include the next digit (2) from the dividend after 69, then repeat: 692 / 670

On to step 3:
670 can be fit into 692 1 times, resulting in a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 670 from 692, we get 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 670

Going ahead to step 4:
670 can be fit into 221 0 times, resulting in a remainder of 221.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 221 to get 221.
Take the next digit (3) from the dividend and append it to 221, then repeat: 2213 / 670

On to step 5:
2213 divided by 670 is 3 with a remainder of 203.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
If we take 2010 away from 2213, we end up with 203.
Include the next digit (3) from the dividend after 203, then repeat: 2033 / 670

Step 6:
670 can be fit into 2033 3 times, resulting in a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 1033.0
If we take 2010 away from 2033, we end up with 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 670

On to step 7:
235 divided by 670 is 0 with a remainder of 235.
Put 0 as the next digit of the answer. 
Result so far: 10330.0
Subtract 0 from 235 to get 235.
Include the next digit (9) from the dividend after 235, then repeat: 2359 / 670

On to step 8:
The number 670 fits into 2359 3 times, leaving a remainder of 349.
The next digit of our result is 3. 
Result so far: 103303.0
Subtract 2010 from 2359 to get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Step 9:
When dividing 3490 by 670, we get 5 with a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 103303.5
The remainder is 140 after subtracting 3350 from 3490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 10:
When dividing 1400 by 670, we get 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 103303.52
The remainder is 60 after subtracting 1340 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 11:
If we divide 600 by 670, we get 0 and a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 103303.52
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 12:
When dividing 6000 by 670, we get 8 with a remainder of 640.
Record the quotient 8 as the next digit in the result. 
Result so far: 103303.5208
Deduct 5360 from 6000 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 13:
If we divide 6400 by 670, we get 9 and a remainder of 370.
The number 9 becomes the next digit in our result. 
Result so far: 103303.52089
Subtract 6030 from 6400 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 14:
670 can be fit into 3700 5 times, resulting in a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 103303.520895
If we take 3350 away from 3700, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 15:
When dividing 3500 by 670, we get 5 with a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 103303.5208955
Subtracting 3350 from 3500 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The quotient of the division is 103303.5208955, and the remainder is 1.5e-06.
