We're dividing 1621656 by 183 
The aim is to understand the frequency of 183 in 1621656.

Moving on to step 1:
The number 183 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 183

Going ahead to step 2:
When dividing 16 by 183, we get 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 183

On to step 3:
162 divided by 183 is 0 with a remainder of 162.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 162 and we're left with 162.
Fetch the next digit (1) from the dividend, attach it to 162 and continue: 1621 / 183

Moving on to step 4:
If we divide 1621 by 183, we get 8 and a remainder of 157.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 157 after subtracting 1464 from 1621.
Append the next digit (6) from the dividend to 157 and continue with: 1576 / 183

On to step 5:
If we divide 1576 by 183, we get 8 and a remainder of 112.
Put 8 as the next digit of the answer. 
Result so far: 88.0
If we take 1464 away from 1576, we end up with 112.
Take the next digit (5) from the dividend and append it to 112, then repeat: 1125 / 183

On to step 6:
1125 divided by 183 is 6 with a remainder of 27.
The next digit of our result is 6. 
Result so far: 886.0
The remainder is 27 after subtracting 1098 from 1125.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 183

On to step 7:
183 can be fit into 276 1 times, resulting in a remainder of 93.
Record the quotient 1 as the next digit in the result. 
Result so far: 8861.0
Subtract 183 from 276 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Moving on to step 8:
930 divided by 183 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 8861.5
Subtract 915 from 930 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
150 divided by 183 is 0 with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 8861.5
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 10:
1500 divided by 183 is 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 8861.508
The remainder is 36 after subtracting 1464 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
360 divided by 183 is 1 with a remainder of 177.
Write down 1 as next digit of the result. 
Result so far: 8861.5081
If we subtract 183 from 360, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 12:
The number 183 fits into 1770 9 times, leaving a remainder of 123.
Use 9 as the next digit of our solution. 
Result so far: 8861.50819
Deduct 1647 from 1770 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 13:
When dividing 1230 by 183, we get 6 with a remainder of 132.
The number 6 becomes the next digit in our result. 
Result so far: 8861.508196
The remainder is 132 after subtracting 1098 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 14:
183 goes into 1320 7 times with a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 8861.5081967
If we take 1281 away from 1320, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 15:
183 goes into 390 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 8861.50819672
If we take 366 away from 390, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 8861.50819672 with a remainder of 2.4e-08.
