We divide 764991 by 42
The aim is to understand the frequency of 42 in 764991.

Going ahead to step 1:
42 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 42

Going ahead to step 2:
If we divide 76 by 42, we get 1 and a remainder of 34.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 42 from 76 to get 34.
Bring next digit (4) of the dividend behind the 34 and repeat the process: 344 / 42

Step 3:
When dividing 344 by 42, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we subtract 336 from 344, we get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 42

Going ahead to step 4:
When dividing 89 by 42, we get 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 182.0
Subtracting 84 from 89 leaves us with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 42

Let's proceed to step 5:
If we divide 59 by 42, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 1821.0
If we take 42 away from 59, we end up with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 42

On to step 6:
42 goes into 171 4 times with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 18214.0
Subtracting 168 from 171 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
42 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 18214.0
Subtract 0 from 30 to 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 8:
300 divided by 42 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 18214.07
Subtract 294 from 300 to 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.

Going ahead to step 9:
60 divided by 42 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 18214.071
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.

On to step 10:
42 can be fit into 180 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 18214.0714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
If we divide 120 by 42, we get 2 and a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 18214.07142
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
42 goes into 360 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 18214.071428
If we subtract 336 from 360, we 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.

Step 13:
240 divided by 42 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 18214.0714285
Subtracting 210 from 240 leaves us 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.

On to step 14:
42 goes into 300 7 times with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 18214.07142857
Subtract 294 from 300 to 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.

The final outcome is 18214.07142857, with a leftover of 6e-09.
