We're dividing 12107996 by 601 
The aim is to understand the frequency of 601 in 12107996.

On to step 1:
If we divide 1 by 601, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 601

Moving on to step 2:
12 divided by 601 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 601

Step 3:
601 goes into 121 0 times with a remainder of 121.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 121 after subtracting 0 from 121.
Fetch the next digit (0) from the dividend, attach it to 121 and continue: 1210 / 601

Advancing to step 4:
The number 601 fits into 1210 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1202 from 1210 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 601

Let's proceed to step 5:
If we divide 87 by 601, we get 0 and a remainder of 87.
The next digit of our result is 0. 
Result so far: 20.0
The remainder is 87 after subtracting 0 from 87.
Fetch the next digit (9) from the dividend, attach it to 87 and continue: 879 / 601

Going ahead to step 6:
601 can be fit into 879 1 times, resulting in a remainder of 278.
Write down 1 as next digit of the result. 
Result so far: 201.0
If we take 601 away from 879, we end up with 278.
Fetch the next digit (9) from the dividend, attach it to 278 and continue: 2789 / 601

Moving on to step 7:
601 can be fit into 2789 4 times, resulting in a remainder of 385.
Write down 4 as next digit of the result. 
Result so far: 2014.0
Subtracting 2404 from 2789 leaves us with 385.
Bring next digit (6) of the dividend behind the 385 and repeat the process: 3856 / 601

Step 8:
The number 601 fits into 3856 6 times, leaving a remainder of 250.
The next digit of our result is 6. 
Result so far: 20146.0
If we subtract 3606 from 3856, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 9:
If we divide 2500 by 601, we get 4 and a remainder of 96.
Record the quotient 4 as the next digit in the result. 
Result so far: 20146.4
If we subtract 2404 from 2500, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 10:
If we divide 960 by 601, we get 1 and a remainder of 359.
Record the quotient 1 as the next digit in the result. 
Result so far: 20146.41
Subtract 601 from 960 to get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

On to step 11:
601 goes into 3590 5 times with a remainder of 585.
Use 5 as the next digit of our solution. 
Result so far: 20146.415
Deduct 3005 from 3590 and we're left with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Let's proceed to step 12:
5850 divided by 601 is 9 with a remainder of 441.
Use 9 as the next digit of our solution. 
Result so far: 20146.4159
Deduct 5409 from 5850 and we're left with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Moving on to step 13:
4410 divided by 601 is 7 with a remainder of 203.
Put 7 as the next digit of the answer. 
Result so far: 20146.41597
Subtracting 4207 from 4410 leaves us with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Moving on to step 14:
2030 divided by 601 is 3 with a remainder of 227.
Record the quotient 3 as the next digit in the result. 
Result so far: 20146.415973
Subtract 1803 from 2030 to get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Step 15:
The number 601 fits into 2270 3 times, leaving a remainder of 467.
Use 3 as the next digit of our solution. 
Result so far: 20146.4159733
Subtract 1803 from 2270 to get 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

The final result is 20146.4159733 with a remainder of 4.67e-06.
