869415 divided by 42 
We want to figure out the number of times 869415 can be divided by 42.

Going ahead to step 1:
If we divide 8 by 42, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 42

Going ahead to step 2:
86 divided by 42 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 84 away from 86, we end up with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 42

Going ahead to step 3:
If we divide 29 by 42, we get 0 and a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Deduct 0 from 29 and we're left with 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 42

Going ahead to step 4:
If we divide 294 by 42, we get 7 and a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 207.0
The remainder is 0 after subtracting 294 from 294.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 42

Let's proceed to step 5:
1 divided by 42 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 2070.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 42

Moving on to step 6:
If we divide 15 by 42, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 20700.0
Subtract 0 from 15 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
The number 42 fits into 150 3 times, leaving a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 20700.3
If we take 126 away from 150, we end up 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.

Let's proceed to step 8:
42 can be fit into 240 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 20700.35
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 9:
42 goes into 300 7 times with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 20700.357
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.

On to step 10:
42 goes into 60 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 20700.3571
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
If we divide 180 by 42, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 20700.35714
If we subtract 168 from 180, we get 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.
Write down 2 as next digit of the result. 
Result so far: 20700.357142
If we take 84 away from 120, we end up 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.

Let's proceed to step 13:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 20700.3571428
Subtracting 336 from 360 leaves us 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: 20700.35714285
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.

In conclusion, the division gives 20700.35714285 with a balance of 3e-08.
