28215004 ÷ 981 
The aim is to understand the frequency of 981 in 28215004.

Let's proceed 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
If we subtract 0 from 2, we get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 981

Moving on to step 2:
The number 981 fits into 28 0 times, leaving a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Include the next digit (2) from the dividend after 28, then repeat: 282 / 981

Moving on to step 3:
282 divided by 981 is 0 with a remainder of 282.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 282 after subtracting 0 from 282.
Include the next digit (1) from the dividend after 282, then repeat: 2821 / 981

Moving on to step 4:
981 can be fit into 2821 2 times, resulting in a remainder of 859.
The next digit of our result is 2. 
Result so far: 2.0
If we take 1962 away from 2821, we end up with 859.
Bring next digit (5) of the dividend behind the 859 and repeat the process: 8595 / 981

On to step 5:
The number 981 fits into 8595 8 times, leaving a remainder of 747.
Use 8 as the next digit of our solution. 
Result so far: 28.0
The remainder is 747 after subtracting 7848 from 8595.
Grab the next digit (0) from the dividend, add it to 747, then carry on: 7470 / 981

Moving on to step 6:
981 goes into 7470 7 times with a remainder of 603.
Record the quotient 7 as the next digit in the result. 
Result so far: 287.0
The remainder is 603 after subtracting 6867 from 7470.
Include the next digit (0) from the dividend after 603, then repeat: 6030 / 981

Advancing to step 7:
6030 divided by 981 is 6 with a remainder of 144.
Record the quotient 6 as the next digit in the result. 
Result so far: 2876.0
Deduct 5886 from 6030 and we're left with 144.
Append the next digit (4) from the dividend to 144 and continue with: 1444 / 981

Advancing to step 8:
When dividing 1444 by 981, we get 1 with a remainder of 463.
Put 1 as the next digit of the answer. 
Result so far: 28761.0
Deduct 981 from 1444 and we're left with 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Going ahead to step 9:
981 goes into 4630 4 times with a remainder of 706.
Record the quotient 4 as the next digit in the result. 
Result so far: 28761.4
The remainder is 706 after subtracting 3924 from 4630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

On to step 10:
981 goes into 7060 7 times with a remainder of 193.
Write down 7 as next digit of the result. 
Result so far: 28761.47
The remainder is 193 after subtracting 6867 from 7060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Step 11:
When dividing 1930 by 981, we get 1 with a remainder of 949.
Use 1 as the next digit of our solution. 
Result so far: 28761.471
The remainder is 949 after subtracting 981 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9490, and continue the process.

Step 12:
When dividing 9490 by 981, we get 9 with a remainder of 661.
Use 9 as the next digit of our solution. 
Result so far: 28761.4719
Deduct 8829 from 9490 and we're left with 661.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6610, and continue the process.

On to step 13:
981 can be fit into 6610 6 times, resulting in a remainder of 724.
Use 6 as the next digit of our solution. 
Result so far: 28761.47196
The remainder is 724 after subtracting 5886 from 6610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Advancing to step 14:
When dividing 7240 by 981, we get 7 with a remainder of 373.
Write down 7 as next digit of the result. 
Result so far: 28761.471967
Subtract 6867 from 7240 to get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Step 15:
If we divide 3730 by 981, we get 3 and a remainder of 787.
Put 3 as the next digit of the answer. 
Result so far: 28761.4719673
If we subtract 2943 from 3730, we get 787.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7870, and continue the process.

On to step 16:
The number 981 fits into 7870 8 times, leaving a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 28761.47196738
Subtract 7848 from 7870 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 28761.47196738 and a remainder of 2.2e-08.
