We look at the division of 17990602 by 884 
The aim is to understand the frequency of 884 in 17990602.

Step 1:
The number 884 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 884

Moving on to step 2:
17 divided by 884 is 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 884

Moving on to step 3:
When dividing 179 by 884, we get 0 with a remainder of 179.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 179 to get 179.
Take the next digit (9) from the dividend and append it to 179, then repeat: 1799 / 884

Going ahead to step 4:
884 goes into 1799 2 times with a remainder of 31.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1768 from 1799 to get 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 884

Moving on to step 5:
310 divided by 884 is 0 with a remainder of 310.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 310 and we're left with 310.
Append the next digit (6) from the dividend to 310 and continue with: 3106 / 884

Moving on to step 6:
3106 divided by 884 is 3 with a remainder of 454.
The next digit of our result is 3. 
Result so far: 203.0
If we take 2652 away from 3106, we end up with 454.
Include the next digit (0) from the dividend after 454, then repeat: 4540 / 884

Step 7:
If we divide 4540 by 884, we get 5 and a remainder of 120.
The number 5 becomes the next digit in our result. 
Result so far: 2035.0
Deduct 4420 from 4540 and we're left with 120.
Take the next digit (2) from the dividend and append it to 120, then repeat: 1202 / 884

Moving on to step 8:
When dividing 1202 by 884, we get 1 with a remainder of 318.
Write down 1 as next digit of the result. 
Result so far: 20351.0
The remainder is 318 after subtracting 884 from 1202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Advancing to step 9:
The number 884 fits into 3180 3 times, leaving a remainder of 528.
Record the quotient 3 as the next digit in the result. 
Result so far: 20351.3
The remainder is 528 after subtracting 2652 from 3180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Step 10:
884 goes into 5280 5 times with a remainder of 860.
Write down 5 as next digit of the result. 
Result so far: 20351.35
The remainder is 860 after subtracting 4420 from 5280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Let's proceed to step 11:
The number 884 fits into 8600 9 times, leaving a remainder of 644.
Record the quotient 9 as the next digit in the result. 
Result so far: 20351.359
If we take 7956 away from 8600, we end up with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

On to step 12:
If we divide 6440 by 884, we get 7 and a remainder of 252.
Write down 7 as next digit of the result. 
Result so far: 20351.3597
Deduct 6188 from 6440 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 13:
The number 884 fits into 2520 2 times, leaving a remainder of 752.
The next digit of our result is 2. 
Result so far: 20351.35972
Subtracting 1768 from 2520 leaves us 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.

Advancing to step 14:
7520 divided by 884 is 8 with a remainder of 448.
Put 8 as the next digit of the answer. 
Result so far: 20351.359728
The remainder is 448 after subtracting 7072 from 7520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 15:
If we divide 4480 by 884, we get 5 and a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 20351.3597285
Subtracting 4420 from 4480 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 16:
600 divided by 884 is 0 with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 20351.3597285
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

After the division, we end up with 20351.3597285 and a remainder of 6e-07.
