2130279 ÷ 907 
The aim is to understand the frequency of 907 in 2130279.

Let's proceed to step 1:
907 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 907

Let's proceed to step 2:
907 goes into 21 0 times with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 907

On to step 3:
907 can be fit into 213 0 times, resulting in a remainder of 213.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 213 after subtracting 0 from 213.
Include the next digit (0) from the dividend after 213, then repeat: 2130 / 907

Moving on to step 4:
The number 907 fits into 2130 2 times, leaving a remainder of 316.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1814 from 2130, we get 316.
Grab the next digit (2) from the dividend, add it to 316, then carry on: 3162 / 907

Step 5:
3162 divided by 907 is 3 with a remainder of 441.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we take 2721 away from 3162, we end up with 441.
Fetch the next digit (7) from the dividend, attach it to 441 and continue: 4417 / 907

Step 6:
If we divide 4417 by 907, we get 4 and a remainder of 789.
Use 4 as the next digit of our solution. 
Result so far: 234.0
If we subtract 3628 from 4417, we get 789.
Fetch the next digit (9) from the dividend, attach it to 789 and continue: 7899 / 907

Step 7:
If we divide 7899 by 907, we get 8 and a remainder of 643.
Record the quotient 8 as the next digit in the result. 
Result so far: 2348.0
The remainder is 643 after subtracting 7256 from 7899.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

Let's proceed to step 8:
If we divide 6430 by 907, we get 7 and a remainder of 81.
The next digit of our result is 7. 
Result so far: 2348.7
Subtracting 6349 from 6430 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 9:
When dividing 810 by 907, we get 0 with a remainder of 810.
Write down 0 as next digit of the result. 
Result so far: 2348.7
Subtract 0 from 810 to get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Moving on to step 10:
907 can be fit into 8100 8 times, resulting in a remainder of 844.
Put 8 as the next digit of the answer. 
Result so far: 2348.708
The remainder is 844 after subtracting 7256 from 8100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

Advancing to step 11:
If we divide 8440 by 907, we get 9 and a remainder of 277.
Use 9 as the next digit of our solution. 
Result so far: 2348.7089
Deduct 8163 from 8440 and we're left with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Advancing to step 12:
907 can be fit into 2770 3 times, resulting in a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 2348.70893
If we subtract 2721 from 2770, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 13:
When dividing 490 by 907, we get 0 with a remainder of 490.
Put 0 as the next digit of the answer. 
Result so far: 2348.70893
Deduct 0 from 490 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 14:
If we divide 4900 by 907, we get 5 and a remainder of 365.
The next digit of our result is 5. 
Result so far: 2348.7089305
The remainder is 365 after subtracting 4535 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

On to step 15:
907 goes into 3650 4 times with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 2348.70893054
Subtract 3628 from 3650 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 2348.70893054, with a leftover of 2.2e-08.
