328913 divided by 42 
The aim is to understand the frequency of 42 in 328913.

Advancing to step 1:
When dividing 3 by 42, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 42

Going ahead to step 2:
42 goes into 32 0 times with a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 32 and we're left with 32.
Take the next digit (8) from the dividend and append it to 32, then repeat: 328 / 42

Going ahead to step 3:
If we divide 328 by 42, we get 7 and a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 294 from 328, we get 34.
Grab the next digit (9) from the dividend, add it to 34, then carry on: 349 / 42

On to step 4:
The number 42 fits into 349 8 times, leaving a remainder of 13.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Subtracting 336 from 349 leaves us with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 42

Moving on to step 5:
If we divide 131 by 42, we get 3 and a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 783.0
Subtracting 126 from 131 leaves us with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 42

On to step 6:
42 can be fit into 53 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 7831.0
Deduct 42 from 53 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
If we divide 110 by 42, we get 2 and a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 7831.2
Subtract 84 from 110 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
The number 42 fits into 260 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 7831.26
Subtract 252 from 260 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 7831.261
If we take 42 away from 80, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
380 divided by 42 is 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 7831.2619
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
20 divided by 42 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 7831.2619
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
If we divide 200 by 42, we get 4 and a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 7831.261904
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
The number 42 fits into 320 7 times, leaving a remainder of 26.
The next digit of our result is 7. 
Result so far: 7831.2619047
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
42 goes into 260 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 7831.26190476
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 7831.26190476 with a balance of 8e-09.
