Let's divide 99950041 by 42
The aim is to understand the frequency of 42 in 99950041.

Advancing to step 1:
9 divided by 42 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 42

Moving on to step 2:
The number 42 fits into 99 2 times, leaving a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 84 from 99 leaves us with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 42

On to step 3:
159 divided by 42 is 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 126 from 159, we get 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 42

Moving on to step 4:
When dividing 335 by 42, we get 7 with a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 237.0
Deduct 294 from 335 and we're left with 41.
Grab the next digit (0) from the dividend, add it to 41, then carry on: 410 / 42

Step 5:
When dividing 410 by 42, we get 9 with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 2379.0
If we take 378 away from 410, we end up with 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 42

Moving on to step 6:
The number 42 fits into 320 7 times, leaving a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 23797.0
Deduct 294 from 320 and we're left with 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 42

Going ahead to step 7:
If we divide 264 by 42, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 237976.0
The remainder is 12 after subtracting 252 from 264.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 42

Going ahead to step 8:
The number 42 fits into 121 2 times, leaving a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 2379762.0
Subtracting 84 from 121 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
When dividing 370 by 42, we get 8 with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 2379762.8
If we take 336 away from 370, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
If we divide 340 by 42, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 2379762.88
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 2379762.88, with a leftover of 0.004.
