9080203 ÷ 670 
The aim is to understand the frequency of 670 in 9080203.

Going ahead to step 1:
When dividing 9 by 670, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 670

Moving on to step 2:
When dividing 90 by 670, we get 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Fetch the next digit (8) from the dividend, attach it to 90 and continue: 908 / 670

On to step 3:
The number 670 fits into 908 1 times, leaving a remainder of 238.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 670 from 908 to get 238.
Take the next digit (0) from the dividend and append it to 238, then repeat: 2380 / 670

Going ahead to step 4:
When dividing 2380 by 670, we get 3 with a remainder of 370.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 370 after subtracting 2010 from 2380.
Include the next digit (2) from the dividend after 370, then repeat: 3702 / 670

Step 5:
670 goes into 3702 5 times with a remainder of 352.
Use 5 as the next digit of our solution. 
Result so far: 135.0
The remainder is 352 after subtracting 3350 from 3702.
Include the next digit (0) from the dividend after 352, then repeat: 3520 / 670

Let's proceed to step 6:
670 can be fit into 3520 5 times, resulting in a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 1355.0
If we take 3350 away from 3520, we end up with 170.
Include the next digit (3) from the dividend after 170, then repeat: 1703 / 670

Step 7:
670 can be fit into 1703 2 times, resulting in a remainder of 363.
Record the quotient 2 as the next digit in the result. 
Result so far: 13552.0
The remainder is 363 after subtracting 1340 from 1703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Going ahead to step 8:
When dividing 3630 by 670, we get 5 with a remainder of 280.
Use 5 as the next digit of our solution. 
Result so far: 13552.5
If we take 3350 away from 3630, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 9:
670 goes into 2800 4 times with a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 13552.54
Subtract 2680 from 2800 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 10:
1200 divided by 670 is 1 with a remainder of 530.
The next digit of our result is 1. 
Result so far: 13552.541
Subtracting 670 from 1200 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 11:
When dividing 5300 by 670, we get 7 with a remainder of 610.
Record the quotient 7 as the next digit in the result. 
Result so far: 13552.5417
If we subtract 4690 from 5300, we get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

On to step 12:
If we divide 6100 by 670, we get 9 and a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 13552.54179
Subtract 6030 from 6100 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 13:
The number 670 fits into 700 1 times, leaving a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 13552.541791
The remainder is 30 after subtracting 670 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
When dividing 300 by 670, we get 0 with a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 13552.541791
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 15:
The number 670 fits into 3000 4 times, leaving a remainder of 320.
Use 4 as the next digit of our solution. 
Result so far: 13552.54179104
Subtracting 2680 from 3000 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The quotient of the division is 13552.54179104, and the remainder is 3.2e-07.
