We look at the division of 22252830 by 987 
The aim is to understand the frequency of 987 in 22252830.

Going ahead to step 1:
If we divide 2 by 987, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 987

Advancing to step 2:
987 can be fit into 22 0 times, resulting in a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 987

Moving on to step 3:
If we divide 222 by 987, we get 0 and a remainder of 222.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 222 to get 222.
Append the next digit (5) from the dividend to 222 and continue with: 2225 / 987

Going ahead to step 4:
987 goes into 2225 2 times with a remainder of 251.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 251 after subtracting 1974 from 2225.
Grab the next digit (2) from the dividend, add it to 251, then carry on: 2512 / 987

Going ahead to step 5:
When dividing 2512 by 987, we get 2 with a remainder of 538.
Use 2 as the next digit of our solution. 
Result so far: 22.0
The remainder is 538 after subtracting 1974 from 2512.
Fetch the next digit (8) from the dividend, attach it to 538 and continue: 5388 / 987

Let's proceed to step 6:
5388 divided by 987 is 5 with a remainder of 453.
The next digit of our result is 5. 
Result so far: 225.0
Subtract 4935 from 5388 to get 453.
Take the next digit (3) from the dividend and append it to 453, then repeat: 4533 / 987

On to step 7:
The number 987 fits into 4533 4 times, leaving a remainder of 585.
Record the quotient 4 as the next digit in the result. 
Result so far: 2254.0
If we subtract 3948 from 4533, we get 585.
Include the next digit (0) from the dividend after 585, then repeat: 5850 / 987

Going ahead to step 8:
When dividing 5850 by 987, we get 5 with a remainder of 915.
The next digit of our result is 5. 
Result so far: 22545.0
The remainder is 915 after subtracting 4935 from 5850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9150, and continue the process.

Advancing to step 9:
The number 987 fits into 9150 9 times, leaving a remainder of 267.
The next digit of our result is 9. 
Result so far: 22545.9
Subtracting 8883 from 9150 leaves us with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

On to step 10:
The number 987 fits into 2670 2 times, leaving a remainder of 696.
The next digit of our result is 2. 
Result so far: 22545.92
The remainder is 696 after subtracting 1974 from 2670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

On to step 11:
The number 987 fits into 6960 7 times, leaving a remainder of 51.
The next digit of our result is 7. 
Result so far: 22545.927
Subtract 6909 from 6960 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 12:
When dividing 510 by 987, we get 0 with a remainder of 510.
Use 0 as the next digit of our solution. 
Result so far: 22545.927
Subtracting 0 from 510 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Moving on to step 13:
The number 987 fits into 5100 5 times, leaving a remainder of 165.
The next digit of our result is 5. 
Result so far: 22545.92705
If we take 4935 away from 5100, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 14:
1650 divided by 987 is 1 with a remainder of 663.
Record the quotient 1 as the next digit in the result. 
Result so far: 22545.927051
The remainder is 663 after subtracting 987 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Moving on to step 15:
If we divide 6630 by 987, we get 6 and a remainder of 708.
Put 6 as the next digit of the answer. 
Result so far: 22545.9270516
Subtracting 5922 from 6630 leaves us with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Advancing to step 16:
987 can be fit into 7080 7 times, resulting in a remainder of 171.
Write down 7 as next digit of the result. 
Result so far: 22545.92705167
Subtracting 6909 from 7080 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Our division results in 22545.92705167 with a remaining 1.71e-07.
