60031207 divided by 405 
The aim is to understand the frequency of 405 in 60031207.

Going ahead to step 1:
405 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 405

Going ahead to step 2:
When dividing 60 by 405, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 60 and we're left with 60.
Bring next digit (0) of the dividend behind the 60 and repeat the process: 600 / 405

Step 3:
600 divided by 405 is 1 with a remainder of 195.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 405 from 600, we get 195.
Include the next digit (3) from the dividend after 195, then repeat: 1953 / 405

Going ahead to step 4:
The number 405 fits into 1953 4 times, leaving a remainder of 333.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 1620 from 1953 and we're left with 333.
Bring next digit (1) of the dividend behind the 333 and repeat the process: 3331 / 405

Advancing to step 5:
The number 405 fits into 3331 8 times, leaving a remainder of 91.
The next digit of our result is 8. 
Result so far: 148.0
Subtract 3240 from 3331 to get 91.
Append the next digit (2) from the dividend to 91 and continue with: 912 / 405

Going ahead to step 6:
If we divide 912 by 405, we get 2 and a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 1482.0
Deduct 810 from 912 and we're left with 102.
Grab the next digit (0) from the dividend, add it to 102, then carry on: 1020 / 405

On to step 7:
405 can be fit into 1020 2 times, resulting in a remainder of 210.
The next digit of our result is 2. 
Result so far: 14822.0
If we take 810 away from 1020, we end up with 210.
Include the next digit (7) from the dividend after 210, then repeat: 2107 / 405

Going ahead to step 8:
405 goes into 2107 5 times with a remainder of 82.
Use 5 as the next digit of our solution. 
Result so far: 148225.0
If we subtract 2025 from 2107, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 9:
405 can be fit into 820 2 times, resulting in a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 148225.2
If we take 810 away from 820, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
405 goes into 100 0 times with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 148225.2
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
When dividing 1000 by 405, we get 2 with a remainder of 190.
The next digit of our result is 2. 
Result so far: 148225.202
Subtracting 810 from 1000 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 12:
1900 divided by 405 is 4 with a remainder of 280.
The number 4 becomes the next digit in our result. 
Result so far: 148225.2024
Subtracting 1620 from 1900 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 13:
When dividing 2800 by 405, we get 6 with a remainder of 370.
Record the quotient 6 as the next digit in the result. 
Result so far: 148225.20246
The remainder is 370 after subtracting 2430 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 14:
3700 divided by 405 is 9 with a remainder of 55.
Write down 9 as next digit of the result. 
Result so far: 148225.202469
The remainder is 55 after subtracting 3645 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 15:
When dividing 550 by 405, we get 1 with a remainder of 145.
Use 1 as the next digit of our solution. 
Result so far: 148225.2024691
The remainder is 145 after subtracting 405 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 16:
1450 divided by 405 is 3 with a remainder of 235.
Put 3 as the next digit of the answer. 
Result so far: 148225.20246913
If we take 1215 away from 1450, we end up with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

After the division, we end up with 148225.20246913 and a remainder of 2.35e-07.
