We look at the division of 12121075 by 707 
The aim is to understand the frequency of 707 in 12121075.

Going ahead to step 1:
The number 707 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 707

Advancing to step 2:
If we divide 12 by 707, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 707

Going ahead to step 3:
707 goes into 121 0 times with a remainder of 121.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 121 leaves us with 121.
Grab the next digit (2) from the dividend, add it to 121, then carry on: 1212 / 707

On to step 4:
707 goes into 1212 1 times with a remainder of 505.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 707 from 1212, we get 505.
Take the next digit (1) from the dividend and append it to 505, then repeat: 5051 / 707

Step 5:
If we divide 5051 by 707, we get 7 and a remainder of 102.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 4949 from 5051, we get 102.
Include the next digit (0) from the dividend after 102, then repeat: 1020 / 707

Moving on to step 6:
If we divide 1020 by 707, we get 1 and a remainder of 313.
Put 1 as the next digit of the answer. 
Result so far: 171.0
If we take 707 away from 1020, we end up with 313.
Grab the next digit (7) from the dividend, add it to 313, then carry on: 3137 / 707

Let's proceed to step 7:
3137 divided by 707 is 4 with a remainder of 309.
Write down 4 as next digit of the result. 
Result so far: 1714.0
Subtracting 2828 from 3137 leaves us with 309.
Bring next digit (5) of the dividend behind the 309 and repeat the process: 3095 / 707

Advancing to step 8:
If we divide 3095 by 707, we get 4 and a remainder of 267.
The number 4 becomes the next digit in our result. 
Result so far: 17144.0
Deduct 2828 from 3095 and we're left with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Going ahead to step 9:
707 can be fit into 2670 3 times, resulting in a remainder of 549.
Use 3 as the next digit of our solution. 
Result so far: 17144.3
Subtract 2121 from 2670 to get 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

On to step 10:
5490 divided by 707 is 7 with a remainder of 541.
Write down 7 as next digit of the result. 
Result so far: 17144.37
Subtracting 4949 from 5490 leaves us with 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Let's proceed to step 11:
707 goes into 5410 7 times with a remainder of 461.
The next digit of our result is 7. 
Result so far: 17144.377
The remainder is 461 after subtracting 4949 from 5410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

In conclusion, the division gives 17144.377 with a balance of 0.0461.
