We look at the division of 57573840 by 786 
The aim is to understand the frequency of 786 in 57573840.

Advancing to step 1:
If we divide 5 by 786, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 786

Let's proceed to step 2:
786 goes into 57 0 times with a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 786

Advancing to step 3:
786 goes into 575 0 times with a remainder of 575.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 575, we get 575.
Grab the next digit (7) from the dividend, add it to 575, then carry on: 5757 / 786

On to step 4:
5757 divided by 786 is 7 with a remainder of 255.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 5502 away from 5757, we end up with 255.
Append the next digit (3) from the dividend to 255 and continue with: 2553 / 786

Going ahead to step 5:
786 can be fit into 2553 3 times, resulting in a remainder of 195.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
Subtracting 2358 from 2553 leaves us with 195.
Fetch the next digit (8) from the dividend, attach it to 195 and continue: 1958 / 786

Going ahead to step 6:
786 can be fit into 1958 2 times, resulting in a remainder of 386.
Record the quotient 2 as the next digit in the result. 
Result so far: 732.0
Subtracting 1572 from 1958 leaves us with 386.
Include the next digit (4) from the dividend after 386, then repeat: 3864 / 786

On to step 7:
The number 786 fits into 3864 4 times, leaving a remainder of 720.
Write down 4 as next digit of the result. 
Result so far: 7324.0
If we take 3144 away from 3864, we end up with 720.
Fetch the next digit (0) from the dividend, attach it to 720 and continue: 7200 / 786

On to step 8:
If we divide 7200 by 786, we get 9 and a remainder of 126.
Write down 9 as next digit of the result. 
Result so far: 73249.0
Subtracting 7074 from 7200 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 9:
If we divide 1260 by 786, we get 1 and a remainder of 474.
The number 1 becomes the next digit in our result. 
Result so far: 73249.1
If we subtract 786 from 1260, we get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Let's proceed to step 10:
When dividing 4740 by 786, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 73249.16
Deduct 4716 from 4740 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
786 goes into 240 0 times with a remainder of 240.
The next digit of our result is 0. 
Result so far: 73249.16
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 12:
2400 divided by 786 is 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 73249.1603
If we subtract 2358 from 2400, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 13:
If we divide 420 by 786, we get 0 and a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 73249.1603
Subtract 0 from 420 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 14:
If we divide 4200 by 786, we get 5 and a remainder of 270.
Write down 5 as next digit of the result. 
Result so far: 73249.160305
Subtract 3930 from 4200 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 15:
786 can be fit into 2700 3 times, resulting in a remainder of 342.
Write down 3 as next digit of the result. 
Result so far: 73249.1603053
Subtracting 2358 from 2700 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 16:
786 can be fit into 3420 4 times, resulting in a remainder of 276.
The next digit of our result is 4. 
Result so far: 73249.16030534
Subtracting 3144 from 3420 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Our division results in 73249.16030534 with a remaining 2.76e-07.
