We look at the division of 40450929 by 981 
The aim is to understand the frequency of 981 in 40450929.

Moving on to step 1:
The number 981 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 981

Step 2:
When dividing 40 by 981, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 981

Advancing to step 3:
The number 981 fits into 404 0 times, leaving a remainder of 404.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 404 to get 404.
Grab the next digit (5) from the dividend, add it to 404, then carry on: 4045 / 981

Moving on to step 4:
The number 981 fits into 4045 4 times, leaving a remainder of 121.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 3924 from 4045 and we're left with 121.
Fetch the next digit (0) from the dividend, attach it to 121 and continue: 1210 / 981

Let's proceed to step 5:
If we divide 1210 by 981, we get 1 and a remainder of 229.
Put 1 as the next digit of the answer. 
Result so far: 41.0
Deduct 981 from 1210 and we're left with 229.
Append the next digit (9) from the dividend to 229 and continue with: 2299 / 981

Moving on to step 6:
2299 divided by 981 is 2 with a remainder of 337.
The next digit of our result is 2. 
Result so far: 412.0
If we subtract 1962 from 2299, we get 337.
Bring next digit (2) of the dividend behind the 337 and repeat the process: 3372 / 981

Let's proceed to step 7:
If we divide 3372 by 981, we get 3 and a remainder of 429.
Put 3 as the next digit of the answer. 
Result so far: 4123.0
Deduct 2943 from 3372 and we're left with 429.
Take the next digit (9) from the dividend and append it to 429, then repeat: 4299 / 981

On to step 8:
4299 divided by 981 is 4 with a remainder of 375.
The number 4 becomes the next digit in our result. 
Result so far: 41234.0
Deduct 3924 from 4299 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 9:
3750 divided by 981 is 3 with a remainder of 807.
Put 3 as the next digit of the answer. 
Result so far: 41234.3
The remainder is 807 after subtracting 2943 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8070, and continue the process.

Going ahead to step 10:
8070 divided by 981 is 8 with a remainder of 222.
Put 8 as the next digit of the answer. 
Result so far: 41234.38
Subtract 7848 from 8070 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 11:
If we divide 2220 by 981, we get 2 and a remainder of 258.
The number 2 becomes the next digit in our result. 
Result so far: 41234.382
Deduct 1962 from 2220 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 12:
When dividing 2580 by 981, we get 2 with a remainder of 618.
Put 2 as the next digit of the answer. 
Result so far: 41234.3822
Deduct 1962 from 2580 and we're left with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

After the division, we end up with 41234.3822 and a remainder of 0.00618.
