We're dividing 22380709 by 987 
The aim is to understand the frequency of 987 in 22380709.

Advancing to step 1:
987 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 987

Moving on to step 2:
The number 987 fits into 22 0 times, leaving a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Grab the next digit (3) from the dividend, add it to 22, then carry on: 223 / 987

Moving on to step 3:
When dividing 223 by 987, we get 0 with a remainder of 223.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 223 leaves us with 223.
Append the next digit (8) from the dividend to 223 and continue with: 2238 / 987

Step 4:
If we divide 2238 by 987, we get 2 and a remainder of 264.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 1974 from 2238 to get 264.
Append the next digit (0) from the dividend to 264 and continue with: 2640 / 987

Going ahead to step 5:
987 goes into 2640 2 times with a remainder of 666.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Deduct 1974 from 2640 and we're left with 666.
Take the next digit (7) from the dividend and append it to 666, then repeat: 6667 / 987

On to step 6:
6667 divided by 987 is 6 with a remainder of 745.
Put 6 as the next digit of the answer. 
Result so far: 226.0
Subtract 5922 from 6667 to get 745.
Fetch the next digit (0) from the dividend, attach it to 745 and continue: 7450 / 987

On to step 7:
7450 divided by 987 is 7 with a remainder of 541.
The number 7 becomes the next digit in our result. 
Result so far: 2267.0
If we take 6909 away from 7450, we end up with 541.
Fetch the next digit (9) from the dividend, attach it to 541 and continue: 5419 / 987

Moving on to step 8:
987 can be fit into 5419 5 times, resulting in a remainder of 484.
Use 5 as the next digit of our solution. 
Result so far: 22675.0
If we take 4935 away from 5419, we end up with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Let's proceed to step 9:
987 can be fit into 4840 4 times, resulting in a remainder of 892.
Write down 4 as next digit of the result. 
Result so far: 22675.4
If we subtract 3948 from 4840, we get 892.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8920, and continue the process.

Going ahead to step 10:
987 goes into 8920 9 times with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 22675.49
Subtracting 8883 from 8920 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 11:
If we divide 370 by 987, we get 0 and a remainder of 370.
The next digit of our result is 0. 
Result so far: 22675.49
Subtract 0 from 370 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 12:
If we divide 3700 by 987, we get 3 and a remainder of 739.
Write down 3 as next digit of the result. 
Result so far: 22675.4903
If we take 2961 away from 3700, we end up with 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

On to step 13:
When dividing 7390 by 987, we get 7 with a remainder of 481.
Record the quotient 7 as the next digit in the result. 
Result so far: 22675.49037
If we subtract 6909 from 7390, we get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Advancing to step 14:
If we divide 4810 by 987, we get 4 and a remainder of 862.
Write down 4 as next digit of the result. 
Result so far: 22675.490374
Subtracting 3948 from 4810 leaves us with 862.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8620, and continue the process.

On to step 15:
When dividing 8620 by 987, we get 8 with a remainder of 724.
The next digit of our result is 8. 
Result so far: 22675.4903748
Deduct 7896 from 8620 and we're left with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Let's proceed to step 16:
7240 divided by 987 is 7 with a remainder of 331.
Record the quotient 7 as the next digit in the result. 
Result so far: 22675.49037487
Subtracting 6909 from 7240 leaves us with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

The final result is 22675.49037487 with a remainder of 3.31e-07.
