869777 divided by 42 
The aim is to understand the frequency of 42 in 869777.

Going ahead to step 1:
When dividing 8 by 42, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 42

Advancing to step 2:
42 goes into 86 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 84 from 86 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 42

On to step 3:
42 goes into 29 0 times with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 29, we get 29.
Include the next digit (7) from the dividend after 29, then repeat: 297 / 42

Moving on to step 4:
42 can be fit into 297 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 207.0
Subtract 294 from 297 to get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 42

Advancing to step 5:
42 goes into 37 0 times with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 2070.0
If we take 0 away from 37, we end up with 37.
Grab the next digit (7) from the dividend, add it to 37, then carry on: 377 / 42

Going ahead to step 6:
If we divide 377 by 42, we get 8 and a remainder of 41.
The next digit of our result is 8. 
Result so far: 20708.0
Subtracting 336 from 377 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 7:
410 divided by 42 is 9 with a remainder of 32.
The next digit of our result is 9. 
Result so far: 20708.9
Subtract 378 from 410 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
320 divided by 42 is 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 20708.97
If we take 294 away from 320, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
The number 42 fits into 260 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 20708.976
Subtract 252 from 260 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
If we divide 80 by 42, we get 1 and a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 20708.9761
If we take 42 away from 80, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 11:
When dividing 380 by 42, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 20708.97619
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
When dividing 20 by 42, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 20708.97619
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
When dividing 200 by 42, we get 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 20708.9761904
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
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: 20708.97619047
Deduct 294 from 320 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 20708.97619047 and a remainder of 2.6e-08.
