Let's divide 1107581 by 405
The aim is to understand the frequency of 405 in 1107581.

Let's proceed to step 1:
405 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 405

Let's proceed to step 2:
When dividing 11 by 405, we get 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 405

Let's proceed to step 3:
If we divide 110 by 405, we get 0 and a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 110, we end up with 110.
Fetch the next digit (7) from the dividend, attach it to 110 and continue: 1107 / 405

Step 4:
The number 405 fits into 1107 2 times, leaving a remainder of 297.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 810 from 1107 and we're left with 297.
Grab the next digit (5) from the dividend, add it to 297, then carry on: 2975 / 405

Advancing to step 5:
When dividing 2975 by 405, we get 7 with a remainder of 140.
The next digit of our result is 7. 
Result so far: 27.0
Deduct 2835 from 2975 and we're left with 140.
Append the next digit (8) from the dividend to 140 and continue with: 1408 / 405

Moving on to step 6:
The number 405 fits into 1408 3 times, leaving a remainder of 193.
Record the quotient 3 as the next digit in the result. 
Result so far: 273.0
Deduct 1215 from 1408 and we're left with 193.
Take the next digit (1) from the dividend and append it to 193, then repeat: 1931 / 405

Going ahead to step 7:
If we divide 1931 by 405, we get 4 and a remainder of 311.
The next digit of our result is 4. 
Result so far: 2734.0
The remainder is 311 after subtracting 1620 from 1931.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

On to step 8:
405 goes into 3110 7 times with a remainder of 275.
Write down 7 as next digit of the result. 
Result so far: 2734.7
The remainder is 275 after subtracting 2835 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 9:
When dividing 2750 by 405, we get 6 with a remainder of 320.
The number 6 becomes the next digit in our result. 
Result so far: 2734.76
Subtracting 2430 from 2750 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 10:
405 goes into 3200 7 times with a remainder of 365.
Record the quotient 7 as the next digit in the result. 
Result so far: 2734.767
If we take 2835 away from 3200, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 11:
405 can be fit into 3650 9 times, resulting in a remainder of 5.
The next digit of our result is 9. 
Result so far: 2734.7679
Deduct 3645 from 3650 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
50 divided by 405 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 2734.7679
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
500 divided by 405 is 1 with a remainder of 95.
Write down 1 as next digit of the result. 
Result so far: 2734.767901
Deduct 405 from 500 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 14:
The number 405 fits into 950 2 times, leaving a remainder of 140.
Write down 2 as next digit of the result. 
Result so far: 2734.7679012
Deduct 810 from 950 and we're left 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.

Going ahead to step 15:
When dividing 1400 by 405, we get 3 with a remainder of 185.
Write down 3 as next digit of the result. 
Result so far: 2734.76790123
The remainder is 185 after subtracting 1215 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

After the division, we end up with 2734.76790123 and a remainder of 1.85e-07.
