We divide 20501049 by 981
The aim is to understand the frequency of 981 in 20501049.

Going ahead to step 1:
The number 981 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 981

Step 2:
981 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 981

Let's proceed to step 3:
If we divide 205 by 981, we get 0 and a remainder of 205.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 205, we end up with 205.
Append the next digit (0) from the dividend to 205 and continue with: 2050 / 981

On to step 4:
When dividing 2050 by 981, we get 2 with a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1962 from 2050 and we're left with 88.
Include the next digit (1) from the dividend after 88, then repeat: 881 / 981

Let's proceed to step 5:
When dividing 881 by 981, we get 0 with a remainder of 881.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 881 to get 881.
Append the next digit (0) from the dividend to 881 and continue with: 8810 / 981

Moving on to step 6:
981 can be fit into 8810 8 times, resulting in a remainder of 962.
The next digit of our result is 8. 
Result so far: 208.0
The remainder is 962 after subtracting 7848 from 8810.
Grab the next digit (4) from the dividend, add it to 962, then carry on: 9624 / 981

Step 7:
9624 divided by 981 is 9 with a remainder of 795.
The number 9 becomes the next digit in our result. 
Result so far: 2089.0
If we take 8829 away from 9624, we end up with 795.
Fetch the next digit (9) from the dividend, attach it to 795 and continue: 7959 / 981

On to step 8:
7959 divided by 981 is 8 with a remainder of 111.
Put 8 as the next digit of the answer. 
Result so far: 20898.0
If we subtract 7848 from 7959, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 9:
1110 divided by 981 is 1 with a remainder of 129.
Put 1 as the next digit of the answer. 
Result so far: 20898.1
Deduct 981 from 1110 and we're left with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Moving on to step 10:
981 can be fit into 1290 1 times, resulting in a remainder of 309.
Record the quotient 1 as the next digit in the result. 
Result so far: 20898.11
If we subtract 981 from 1290, we get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

After the division, we end up with 20898.11 and a remainder of 0.309.
