We're dividing 686055 by 42 
The aim is to understand the frequency of 42 in 686055.

Step 1:
42 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 42

Going ahead to step 2:
68 divided by 42 is 1 with a remainder of 26.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 42 from 68, we get 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 42

Going ahead to step 3:
The number 42 fits into 266 6 times, leaving a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 252 from 266 and we're left with 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 42

Step 4:
140 divided by 42 is 3 with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 163.0
Deduct 126 from 140 and we're left with 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 42

Advancing to step 5:
When dividing 145 by 42, we get 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 1633.0
The remainder is 19 after subtracting 126 from 145.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 42

Going ahead to step 6:
If we divide 195 by 42, we get 4 and a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 16334.0
Deduct 168 from 195 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
If we divide 270 by 42, we get 6 and a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 16334.6
The remainder is 18 after subtracting 252 from 270.
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 8:
180 divided by 42 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 16334.64
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
120 divided by 42 is 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 16334.642
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.

Advancing to step 10:
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: 16334.6428
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.

Step 11:
If we divide 240 by 42, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 16334.64285
Deduct 210 from 240 and we're left 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.

Step 12:
300 divided by 42 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 16334.642857
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.

Let's proceed to step 13:
42 goes into 60 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 16334.6428571
The remainder is 18 after subtracting 42 from 60.
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 14:
When dividing 180 by 42, we get 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 16334.64285714
If we take 168 away from 180, we end up 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.

The quotient of the division is 16334.64285714, and the remainder is 1.2e-08.
