82187844 ÷ 405 
The aim is to understand the frequency of 405 in 82187844.

Moving on to step 1:
405 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 405

Advancing to step 2:
405 goes into 82 0 times with a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 82 to get 82.
Include the next digit (1) from the dividend after 82, then repeat: 821 / 405

On to step 3:
When dividing 821 by 405, we get 2 with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 810 from 821 leaves us with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 405

Moving on to step 4:
If we divide 118 by 405, we get 0 and a remainder of 118.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 118 leaves us with 118.
Include the next digit (7) from the dividend after 118, then repeat: 1187 / 405

Advancing to step 5:
If we divide 1187 by 405, we get 2 and a remainder of 377.
Put 2 as the next digit of the answer. 
Result so far: 202.0
If we subtract 810 from 1187, we get 377.
Fetch the next digit (8) from the dividend, attach it to 377 and continue: 3778 / 405

Going ahead to step 6:
405 goes into 3778 9 times with a remainder of 133.
The next digit of our result is 9. 
Result so far: 2029.0
If we take 3645 away from 3778, we end up with 133.
Grab the next digit (4) from the dividend, add it to 133, then carry on: 1334 / 405

Going ahead to step 7:
When dividing 1334 by 405, we get 3 with a remainder of 119.
Put 3 as the next digit of the answer. 
Result so far: 20293.0
Subtract 1215 from 1334 to get 119.
Grab the next digit (4) from the dividend, add it to 119, then carry on: 1194 / 405

Advancing to step 8:
If we divide 1194 by 405, we get 2 and a remainder of 384.
Record the quotient 2 as the next digit in the result. 
Result so far: 202932.0
If we subtract 810 from 1194, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 9:
If we divide 3840 by 405, we get 9 and a remainder of 195.
The number 9 becomes the next digit in our result. 
Result so far: 202932.9
Subtract 3645 from 3840 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 10:
If we divide 1950 by 405, we get 4 and a remainder of 330.
Put 4 as the next digit of the answer. 
Result so far: 202932.94
Deduct 1620 from 1950 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 11:
405 goes into 3300 8 times with a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 202932.948
Subtracting 3240 from 3300 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.

On to step 12:
The number 405 fits into 600 1 times, leaving a remainder of 195.
The number 1 becomes the next digit in our result. 
Result so far: 202932.9481
If we subtract 405 from 600, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 13:
405 goes into 1950 4 times with a remainder of 330.
Record the quotient 4 as the next digit in the result. 
Result so far: 202932.94814
If we subtract 1620 from 1950, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 14:
The number 405 fits into 3300 8 times, leaving a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 202932.948148
If we take 3240 away from 3300, we end up 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.

On to step 15:
600 divided by 405 is 1 with a remainder of 195.
The number 1 becomes the next digit in our result. 
Result so far: 202932.9481481
If we subtract 405 from 600, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 16:
If we divide 1950 by 405, we get 4 and a remainder of 330.
The next digit of our result is 4. 
Result so far: 202932.94814814
Subtracting 1620 from 1950 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Our division results in 202932.94814814 with a remaining 3.3e-07.
