We're dividing 21578122 by 982 
The aim is to understand the frequency of 982 in 21578122.

Moving on to step 1:
The number 982 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 982

Moving on to step 2:
982 goes into 21 0 times with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 982

Advancing to step 3:
When dividing 215 by 982, we get 0 with a remainder of 215.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 215, we get 215.
Take the next digit (7) from the dividend and append it to 215, then repeat: 2157 / 982

Going ahead to step 4:
982 can be fit into 2157 2 times, resulting in a remainder of 193.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1964 from 2157 leaves us with 193.
Fetch the next digit (8) from the dividend, attach it to 193 and continue: 1938 / 982

Advancing to step 5:
When dividing 1938 by 982, we get 1 with a remainder of 956.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 982 from 1938, we get 956.
Fetch the next digit (1) from the dividend, attach it to 956 and continue: 9561 / 982

Going ahead to step 6:
If we divide 9561 by 982, we get 9 and a remainder of 723.
Use 9 as the next digit of our solution. 
Result so far: 219.0
Deduct 8838 from 9561 and we're left with 723.
Bring next digit (2) of the dividend behind the 723 and repeat the process: 7232 / 982

On to step 7:
The number 982 fits into 7232 7 times, leaving a remainder of 358.
Record the quotient 7 as the next digit in the result. 
Result so far: 2197.0
If we take 6874 away from 7232, we end up with 358.
Fetch the next digit (2) from the dividend, attach it to 358 and continue: 3582 / 982

Moving on to step 8:
3582 divided by 982 is 3 with a remainder of 636.
Use 3 as the next digit of our solution. 
Result so far: 21973.0
Subtracting 2946 from 3582 leaves us with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Going ahead to step 9:
When dividing 6360 by 982, we get 6 with a remainder of 468.
Write down 6 as next digit of the result. 
Result so far: 21973.6
The remainder is 468 after subtracting 5892 from 6360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

On to step 10:
The number 982 fits into 4680 4 times, leaving a remainder of 752.
Record the quotient 4 as the next digit in the result. 
Result so far: 21973.64
If we take 3928 away from 4680, we end up with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Going ahead to step 11:
The number 982 fits into 7520 7 times, leaving a remainder of 646.
The next digit of our result is 7. 
Result so far: 21973.647
If we subtract 6874 from 7520, we get 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Moving on to step 12:
6460 divided by 982 is 6 with a remainder of 568.
Write down 6 as next digit of the result. 
Result so far: 21973.6476
Subtracting 5892 from 6460 leaves us with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Moving on to step 13:
If we divide 5680 by 982, we get 5 and a remainder of 770.
Record the quotient 5 as the next digit in the result. 
Result so far: 21973.64765
The remainder is 770 after subtracting 4910 from 5680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Going ahead to step 14:
When dividing 7700 by 982, we get 7 with a remainder of 826.
Put 7 as the next digit of the answer. 
Result so far: 21973.647657
If we subtract 6874 from 7700, we get 826.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8260, and continue the process.

Step 15:
982 can be fit into 8260 8 times, resulting in a remainder of 404.
Put 8 as the next digit of the answer. 
Result so far: 21973.6476578
The remainder is 404 after subtracting 7856 from 8260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 16:
982 goes into 4040 4 times with a remainder of 112.
Write down 4 as next digit of the result. 
Result so far: 21973.64765784
Deduct 3928 from 4040 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final outcome is 21973.64765784, with a leftover of 1.12e-07.
