We look at the division of 40661212 by 610 
The aim is to understand the frequency of 610 in 40661212.

Going ahead to step 1:
The number 610 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 610

Advancing to step 2:
If we divide 40 by 610, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 610

Let's proceed to step 3:
610 can be fit into 406 0 times, resulting in a remainder of 406.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 406 leaves us with 406.
Bring next digit (6) of the dividend behind the 406 and repeat the process: 4066 / 610

Going ahead to step 4:
If we divide 4066 by 610, we get 6 and a remainder of 406.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 3660 from 4066, we get 406.
Take the next digit (1) from the dividend and append it to 406, then repeat: 4061 / 610

On to step 5:
The number 610 fits into 4061 6 times, leaving a remainder of 401.
Write down 6 as next digit of the result. 
Result so far: 66.0
Subtracting 3660 from 4061 leaves us with 401.
Fetch the next digit (2) from the dividend, attach it to 401 and continue: 4012 / 610

Advancing to step 6:
610 goes into 4012 6 times with a remainder of 352.
The number 6 becomes the next digit in our result. 
Result so far: 666.0
If we take 3660 away from 4012, we end up with 352.
Append the next digit (1) from the dividend to 352 and continue with: 3521 / 610

Step 7:
3521 divided by 610 is 5 with a remainder of 471.
Put 5 as the next digit of the answer. 
Result so far: 6665.0
If we take 3050 away from 3521, we end up with 471.
Bring next digit (2) of the dividend behind the 471 and repeat the process: 4712 / 610

Going ahead to step 8:
610 can be fit into 4712 7 times, resulting in a remainder of 442.
Use 7 as the next digit of our solution. 
Result so far: 66657.0
Subtracting 4270 from 4712 leaves us with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Let's proceed to step 9:
610 can be fit into 4420 7 times, resulting in a remainder of 150.
Put 7 as the next digit of the answer. 
Result so far: 66657.7
Subtracting 4270 from 4420 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 10:
The number 610 fits into 1500 2 times, leaving a remainder of 280.
The next digit of our result is 2. 
Result so far: 66657.72
Deduct 1220 from 1500 and we're left 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.

Moving on to step 11:
The number 610 fits into 2800 4 times, leaving a remainder of 360.
Use 4 as the next digit of our solution. 
Result so far: 66657.724
If we subtract 2440 from 2800, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 12:
The number 610 fits into 3600 5 times, leaving a remainder of 550.
Write down 5 as next digit of the result. 
Result so far: 66657.7245
If we take 3050 away from 3600, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 13:
When dividing 5500 by 610, we get 9 with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 66657.72459
Deduct 5490 from 5500 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
When dividing 100 by 610, we get 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 66657.72459
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 15:
610 goes into 1000 1 times with a remainder of 390.
Record the quotient 1 as the next digit in the result. 
Result so far: 66657.7245901
If we take 610 away from 1000, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 16:
If we divide 3900 by 610, we get 6 and a remainder of 240.
The number 6 becomes the next digit in our result. 
Result so far: 66657.72459016
Deduct 3660 from 3900 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 66657.72459016 with a remainder of 2.4e-07.
