386754 divided by 42 
The aim is to understand the frequency of 42 in 386754.

Advancing to step 1:
The number 42 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 42

Step 2:
42 goes into 38 0 times with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 42

Step 3:
The number 42 fits into 386 9 times, leaving a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 8 after subtracting 378 from 386.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 42

Advancing to step 4:
The number 42 fits into 87 2 times, leaving a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 92.0
Deduct 84 from 87 and we're left with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 42

Going ahead to step 5:
42 can be fit into 35 0 times, resulting in a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 920.0
The remainder is 35 after subtracting 0 from 35.
Grab the next digit (4) from the dividend, add it to 35, then carry on: 354 / 42

On to step 6:
354 divided by 42 is 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 9208.0
The remainder is 18 after subtracting 336 from 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
If we divide 180 by 42, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 9208.4
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
The number 42 fits into 120 2 times, leaving a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 9208.42
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
360 divided by 42 is 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 9208.428
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
42 goes into 240 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 9208.4285
If we take 210 away from 240, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
300 divided by 42 is 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 9208.42857
Subtracting 294 from 300 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
If we divide 60 by 42, we get 1 and a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 9208.428571
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 9208.4285714
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 9208.42857142
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The quotient of the division is 9208.42857142, and the remainder is 3.6e-08.
