We look at the division of 56859684 by 405 
The aim is to understand the frequency of 405 in 56859684.

On to step 1:
If we divide 5 by 405, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 405

On to step 2:
405 can be fit into 56 0 times, resulting in a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Take the next digit (8) from the dividend and append it to 56, then repeat: 568 / 405

On to step 3:
If we divide 568 by 405, we get 1 and a remainder of 163.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 405 from 568, we get 163.
Take the next digit (5) from the dividend and append it to 163, then repeat: 1635 / 405

Going ahead to step 4:
The number 405 fits into 1635 4 times, leaving a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 15 after subtracting 1620 from 1635.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 405

Step 5:
405 can be fit into 159 0 times, resulting in a remainder of 159.
Put 0 as the next digit of the answer. 
Result so far: 140.0
If we take 0 away from 159, we end up with 159.
Bring next digit (6) of the dividend behind the 159 and repeat the process: 1596 / 405

Advancing to step 6:
1596 divided by 405 is 3 with a remainder of 381.
Put 3 as the next digit of the answer. 
Result so far: 1403.0
If we subtract 1215 from 1596, we get 381.
Take the next digit (8) from the dividend and append it to 381, then repeat: 3818 / 405

Let's proceed to step 7:
If we divide 3818 by 405, we get 9 and a remainder of 173.
Write down 9 as next digit of the result. 
Result so far: 14039.0
Deduct 3645 from 3818 and we're left with 173.
Grab the next digit (4) from the dividend, add it to 173, then carry on: 1734 / 405

Let's proceed to step 8:
405 can be fit into 1734 4 times, resulting in a remainder of 114.
Put 4 as the next digit of the answer. 
Result so far: 140394.0
If we take 1620 away from 1734, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 9:
1140 divided by 405 is 2 with a remainder of 330.
Write down 2 as next digit of the result. 
Result so far: 140394.2
Deduct 810 from 1140 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.

Moving on to step 10:
When dividing 3300 by 405, we get 8 with a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 140394.28
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.

Going ahead to step 11:
If we divide 600 by 405, we get 1 and a remainder of 195.
Write down 1 as next digit of the result. 
Result so far: 140394.281
Subtract 405 from 600 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.

Moving on to step 12:
The number 405 fits into 1950 4 times, leaving a remainder of 330.
Record the quotient 4 as the next digit in the result. 
Result so far: 140394.2814
The remainder is 330 after subtracting 1620 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 13:
The number 405 fits into 3300 8 times, leaving a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 140394.28148
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.

Let's proceed to step 14:
If we divide 600 by 405, we get 1 and a remainder of 195.
Record the quotient 1 as the next digit in the result. 
Result so far: 140394.281481
If we take 405 away from 600, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Going ahead to step 15:
1950 divided by 405 is 4 with a remainder of 330.
Record the quotient 4 as the next digit in the result. 
Result so far: 140394.2814814
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.

Step 16:
The number 405 fits into 3300 8 times, leaving a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 140394.28148148
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.

Our division results in 140394.28148148 with a remaining 6e-08.
