961201 divided by 42 
The aim is to understand the frequency of 42 in 961201.

Going ahead to step 1:
42 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 42

Advancing to step 2:
If we divide 96 by 42, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 84 from 96 leaves us with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 42

Moving on to step 3:
If we divide 121 by 42, we get 2 and a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we take 84 away from 121, we end up with 37.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 42

On to step 4:
When dividing 372 by 42, we get 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 228.0
Deduct 336 from 372 and we're left with 36.
Fetch the next digit (0) from the dividend, attach it to 36 and continue: 360 / 42

On to step 5:
The number 42 fits into 360 8 times, leaving a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 2288.0
Subtract 336 from 360 to get 24.
Take the next digit (1) from the dividend and append it to 24, then repeat: 241 / 42

Advancing to step 6:
If we divide 241 by 42, we get 5 and a remainder of 31.
Write down 5 as next digit of the result. 
Result so far: 22885.0
Subtracting 210 from 241 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
310 divided by 42 is 7 with a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 22885.7
If we take 294 away from 310, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
When dividing 160 by 42, we get 3 with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 22885.73
Subtracting 126 from 160 leaves us 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.

Step 9:
42 goes into 340 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 22885.738
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
The number 42 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 22885.738
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
The number 42 fits into 400 9 times, leaving a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 22885.73809
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
When dividing 220 by 42, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 22885.738095
Deduct 210 from 220 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 22885.7380952
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
If we divide 160 by 42, we get 3 and a remainder of 34.
The next digit of our result is 3. 
Result so far: 22885.73809523
Subtracting 126 from 160 leaves us 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.

The quotient of the division is 22885.73809523, and the remainder is 3.4e-08.
