We're dividing 6623651 by 181 
The aim is to understand the frequency of 181 in 6623651.

Let's proceed to step 1:
181 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 181

On to step 2:
When dividing 66 by 181, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Include the next digit (2) from the dividend after 66, then repeat: 662 / 181

Let's proceed to step 3:
If we divide 662 by 181, we get 3 and a remainder of 119.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 543 from 662, we get 119.
Append the next digit (3) from the dividend to 119 and continue with: 1193 / 181

Step 4:
When dividing 1193 by 181, we get 6 with a remainder of 107.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtract 1086 from 1193 to get 107.
Append the next digit (6) from the dividend to 107 and continue with: 1076 / 181

Step 5:
1076 divided by 181 is 5 with a remainder of 171.
The next digit of our result is 5. 
Result so far: 365.0
The remainder is 171 after subtracting 905 from 1076.
Append the next digit (5) from the dividend to 171 and continue with: 1715 / 181

Going ahead to step 6:
181 can be fit into 1715 9 times, resulting in a remainder of 86.
Use 9 as the next digit of our solution. 
Result so far: 3659.0
Deduct 1629 from 1715 and we're left with 86.
Bring next digit (1) of the dividend behind the 86 and repeat the process: 861 / 181

Step 7:
181 goes into 861 4 times with a remainder of 137.
Put 4 as the next digit of the answer. 
Result so far: 36594.0
Subtracting 724 from 861 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 8:
181 goes into 1370 7 times with a remainder of 103.
Write down 7 as next digit of the result. 
Result so far: 36594.7
Subtract 1267 from 1370 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 9:
If we divide 1030 by 181, we get 5 and a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 36594.75
If we subtract 905 from 1030, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 10:
The number 181 fits into 1250 6 times, leaving a remainder of 164.
Put 6 as the next digit of the answer. 
Result so far: 36594.756
If we subtract 1086 from 1250, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 11:
If we divide 1640 by 181, we get 9 and a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 36594.7569
If we subtract 1629 from 1640, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
181 can be fit into 110 0 times, resulting in a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 36594.7569
If we subtract 0 from 110, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 13:
181 can be fit into 1100 6 times, resulting in a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 36594.756906
Deduct 1086 from 1100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
If we divide 140 by 181, we get 0 and a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 36594.756906
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 15:
When dividing 1400 by 181, we get 7 with a remainder of 133.
Use 7 as the next digit of our solution. 
Result so far: 36594.75690607
Subtract 1267 from 1400 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

After the division, we end up with 36594.75690607 and a remainder of 1.33e-07.
