801102 divided by 42 
The aim is to understand the frequency of 42 in 801102.

On to step 1:
42 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 42

Moving on to step 2:
42 goes into 80 1 times with a remainder of 38.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 42 from 80 and we're left with 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 42

Let's proceed to step 3:
42 goes into 381 9 times with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 378 away from 381, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 42

On to step 4:
42 goes into 31 0 times with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 190.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 42

On to step 5:
42 goes into 310 7 times with a remainder of 16.
The next digit of our result is 7. 
Result so far: 1907.0
Subtracting 294 from 310 leaves us with 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 42

Going ahead to step 6:
162 divided by 42 is 3 with a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 19073.0
The remainder is 36 after subtracting 126 from 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
42 goes into 360 8 times with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 19073.8
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.

Moving on to step 8:
42 goes into 240 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 19073.85
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 19073.857
If we subtract 294 from 300, we get 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 10:
When dividing 60 by 42, we get 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 19073.8571
Subtract 42 from 60 to 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 11:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 19073.85714
Subtracting 168 from 180 leaves us 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.

Let's proceed to step 12:
When dividing 120 by 42, we get 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 19073.857142
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.

Step 13:
42 can be fit into 360 8 times, resulting in a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 19073.8571428
Deduct 336 from 360 and we're left 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.

Advancing to step 14:
240 divided by 42 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 19073.85714285
If we take 210 away from 240, we end up 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.

The final outcome is 19073.85714285, with a leftover of 3e-08.
