We're dividing 42736981 by 427 
The aim is to understand the frequency of 427 in 42736981.

Going ahead to step 1:
When dividing 4 by 427, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 427

Going ahead to step 2:
427 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (7) from the dividend, add it to 42, then carry on: 427 / 427

On to step 3:
If we divide 427 by 427, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 427 from 427 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 427

Step 4:
When dividing 3 by 427, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 427

Going ahead to step 5:
If we divide 36 by 427, we get 0 and a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Subtracting 0 from 36 leaves us with 36.
Fetch the next digit (9) from the dividend, attach it to 36 and continue: 369 / 427

Going ahead to step 6:
If we divide 369 by 427, we get 0 and a remainder of 369.
Put 0 as the next digit of the answer. 
Result so far: 1000.0
If we subtract 0 from 369, we get 369.
Bring next digit (8) of the dividend behind the 369 and repeat the process: 3698 / 427

Let's proceed to step 7:
When dividing 3698 by 427, we get 8 with a remainder of 282.
The number 8 becomes the next digit in our result. 
Result so far: 10008.0
Subtract 3416 from 3698 to get 282.
Grab the next digit (1) from the dividend, add it to 282, then carry on: 2821 / 427

Step 8:
427 goes into 2821 6 times with a remainder of 259.
Put 6 as the next digit of the answer. 
Result so far: 100086.0
The remainder is 259 after subtracting 2562 from 2821.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

On to step 9:
When dividing 2590 by 427, we get 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 100086.6
If we take 2562 away from 2590, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
427 can be fit into 280 0 times, resulting in a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 100086.6
Deduct 0 from 280 and we're left 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.

Step 11:
If we divide 2800 by 427, we get 6 and a remainder of 238.
Record the quotient 6 as the next digit in the result. 
Result so far: 100086.606
Subtract 2562 from 2800 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Going ahead to step 12:
2380 divided by 427 is 5 with a remainder of 245.
Write down 5 as next digit of the result. 
Result so far: 100086.6065
Subtract 2135 from 2380 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Advancing to step 13:
2450 divided by 427 is 5 with a remainder of 315.
Record the quotient 5 as the next digit in the result. 
Result so far: 100086.60655
If we subtract 2135 from 2450, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

The quotient of the division is 100086.60655, and the remainder is 0.000315.
