We're dividing 763107 by 42 
The aim is to understand the frequency of 42 in 763107.

On to step 1:
42 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 42

Moving on to step 2:
When dividing 76 by 42, we get 1 with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 34 after subtracting 42 from 76.
Bring next digit (3) of the dividend behind the 34 and repeat the process: 343 / 42

On to step 3:
If we divide 343 by 42, we get 8 and a remainder of 7.
The next digit of our result is 8. 
Result so far: 18.0
If we take 336 away from 343, we end up with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 42

Going ahead to step 4:
42 can be fit into 71 1 times, resulting in a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 181.0
Deduct 42 from 71 and we're left with 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 42

Let's proceed to step 5:
42 can be fit into 290 6 times, resulting in a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 1816.0
Deduct 252 from 290 and we're left with 38.
Fetch the next digit (7) from the dividend, attach it to 38 and continue: 387 / 42

On to step 6:
42 can be fit into 387 9 times, resulting in a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 18169.0
If we subtract 378 from 387, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
If we divide 90 by 42, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 18169.2
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
42 can be fit into 60 1 times, resulting in a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 18169.21
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
42 can be fit into 180 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 18169.214
Deduct 168 from 180 and we're left 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.

Going ahead to step 10:
When dividing 120 by 42, we get 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 18169.2142
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.

Advancing to step 11:
When dividing 360 by 42, we get 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 18169.21428
Subtracting 336 from 360 leaves us 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.

Let's proceed to step 12:
42 can be fit into 240 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 18169.214285
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.

Moving on to step 13:
If we divide 300 by 42, we get 7 and a remainder of 6.
The next digit of our result is 7. 
Result so far: 18169.2142857
Deduct 294 from 300 and we're left 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.

Moving on to step 14:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 18169.21428571
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.

Our division results in 18169.21428571 with a remaining 1.8e-08.
