We're dividing 12427813 by 786 
The aim is to understand the frequency of 786 in 12427813.

Let's proceed to step 1:
If we divide 1 by 786, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 786

Going ahead to step 2:
When dividing 12 by 786, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 786

Step 3:
When dividing 124 by 786, we get 0 with a remainder of 124.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 124, we end up with 124.
Grab the next digit (2) from the dividend, add it to 124, then carry on: 1242 / 786

Advancing to step 4:
786 goes into 1242 1 times with a remainder of 456.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 786 from 1242 to get 456.
Append the next digit (7) from the dividend to 456 and continue with: 4567 / 786

Going ahead to step 5:
786 can be fit into 4567 5 times, resulting in a remainder of 637.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 3930 from 4567, we get 637.
Bring next digit (8) of the dividend behind the 637 and repeat the process: 6378 / 786

Let's proceed to step 6:
When dividing 6378 by 786, we get 8 with a remainder of 90.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
The remainder is 90 after subtracting 6288 from 6378.
Take the next digit (1) from the dividend and append it to 90, then repeat: 901 / 786

Going ahead to step 7:
901 divided by 786 is 1 with a remainder of 115.
Record the quotient 1 as the next digit in the result. 
Result so far: 1581.0
Subtracting 786 from 901 leaves us with 115.
Grab the next digit (3) from the dividend, add it to 115, then carry on: 1153 / 786

Going ahead to step 8:
786 can be fit into 1153 1 times, resulting in a remainder of 367.
Use 1 as the next digit of our solution. 
Result so far: 15811.0
Deduct 786 from 1153 and we're left with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

On to step 9:
786 goes into 3670 4 times with a remainder of 526.
The number 4 becomes the next digit in our result. 
Result so far: 15811.4
Subtracting 3144 from 3670 leaves us with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Advancing to step 10:
5260 divided by 786 is 6 with a remainder of 544.
The next digit of our result is 6. 
Result so far: 15811.46
The remainder is 544 after subtracting 4716 from 5260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

On to step 11:
If we divide 5440 by 786, we get 6 and a remainder of 724.
Write down 6 as next digit of the result. 
Result so far: 15811.466
If we take 4716 away from 5440, we end up with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

The final outcome is 15811.466, with a leftover of 0.0724.
