We're dividing 706873 by 42 
The aim is to understand the frequency of 42 in 706873.

Moving on to step 1:
The number 42 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 42

Going ahead to step 2:
42 goes into 70 1 times with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 42 from 70, we get 28.
Append the next digit (6) from the dividend to 28 and continue with: 286 / 42

On to step 3:
When dividing 286 by 42, we get 6 with a remainder of 34.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 252 from 286, we get 34.
Append the next digit (8) from the dividend to 34 and continue with: 348 / 42

Advancing to step 4:
348 divided by 42 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 168.0
The remainder is 12 after subtracting 336 from 348.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 42

Step 5:
If we divide 127 by 42, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 1683.0
The remainder is 1 after subtracting 126 from 127.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 42

Let's proceed to step 6:
42 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 16830.0
If we take 0 away from 13, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
42 goes into 130 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 16830.3
If we subtract 126 from 130, we 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.

On to step 8:
40 divided by 42 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 16830.3
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
If we divide 400 by 42, we get 9 and a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 16830.309
If we subtract 378 from 400, we 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 10:
The number 42 fits into 220 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 16830.3095
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.

Advancing to step 11:
100 divided by 42 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 16830.30952
Deduct 84 from 100 and we're left 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 12:
42 goes into 160 3 times with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 16830.309523
The remainder is 34 after subtracting 126 from 160.
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 13:
If we divide 340 by 42, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 16830.3095238
Subtracting 336 from 340 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
42 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 16830.3095238
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 16830.3095238 with a remaining 4e-08.
