We look at the division of 70563849 by 670 
The aim is to understand the frequency of 670 in 70563849.

Advancing to step 1:
670 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 670

Moving on to step 2:
70 divided by 670 is 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Fetch the next digit (5) from the dividend, attach it to 70 and continue: 705 / 670

Advancing to step 3:
The number 670 fits into 705 1 times, leaving a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 670 from 705, we get 35.
Include the next digit (6) from the dividend after 35, then repeat: 356 / 670

On to step 4:
356 divided by 670 is 0 with a remainder of 356.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 356 to get 356.
Fetch the next digit (3) from the dividend, attach it to 356 and continue: 3563 / 670

Moving on to step 5:
The number 670 fits into 3563 5 times, leaving a remainder of 213.
The next digit of our result is 5. 
Result so far: 105.0
If we take 3350 away from 3563, we end up with 213.
Fetch the next digit (8) from the dividend, attach it to 213 and continue: 2138 / 670

Advancing to step 6:
When dividing 2138 by 670, we get 3 with a remainder of 128.
The next digit of our result is 3. 
Result so far: 1053.0
The remainder is 128 after subtracting 2010 from 2138.
Grab the next digit (4) from the dividend, add it to 128, then carry on: 1284 / 670

Let's proceed to step 7:
If we divide 1284 by 670, we get 1 and a remainder of 614.
Put 1 as the next digit of the answer. 
Result so far: 10531.0
Subtracting 670 from 1284 leaves us with 614.
Bring next digit (9) of the dividend behind the 614 and repeat the process: 6149 / 670

Moving on to step 8:
670 can be fit into 6149 9 times, resulting in a remainder of 119.
The next digit of our result is 9. 
Result so far: 105319.0
The remainder is 119 after subtracting 6030 from 6149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 9:
670 can be fit into 1190 1 times, resulting in a remainder of 520.
Use 1 as the next digit of our solution. 
Result so far: 105319.1
If we take 670 away from 1190, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 10:
670 goes into 5200 7 times with a remainder of 510.
The number 7 becomes the next digit in our result. 
Result so far: 105319.17
If we take 4690 away from 5200, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 11:
5100 divided by 670 is 7 with a remainder of 410.
Record the quotient 7 as the next digit in the result. 
Result so far: 105319.177
Subtract 4690 from 5100 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

The final result is 105319.177 with a remainder of 0.041.
