878739 divided by 42 
We want to divide 878739 by 42.

Moving on to step 1:
42 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 42

Step 2:
When dividing 87 by 42, we get 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 84 away from 87, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 42

On to step 3:
42 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 38, we end up with 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 42

On to step 4:
When dividing 387 by 42, we get 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 209.0
The remainder is 9 after subtracting 378 from 387.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 42

Moving on to step 5:
The number 42 fits into 93 2 times, leaving a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 2092.0
Deduct 84 from 93 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 42

Moving on to step 6:
99 divided by 42 is 2 with a remainder of 15.
The next digit of our result is 2. 
Result so far: 20922.0
Deduct 84 from 99 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
The number 42 fits into 150 3 times, leaving a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 20922.3
Subtract 126 from 150 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.

Going ahead to step 8:
When dividing 240 by 42, we get 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 20922.35
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.

Advancing to step 9:
If we divide 300 by 42, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 20922.357
Subtracting 294 from 300 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
When dividing 60 by 42, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 20922.3571
If we subtract 42 from 60, we 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:
42 goes into 180 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 20922.35714
If we take 168 away from 180, we end up 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: 20922.357142
Deduct 84 from 120 and we're left 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.

Step 13:
If we divide 360 by 42, we get 8 and a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 20922.3571428
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.

Step 14:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 20922.35714285
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.

Our division results in 20922.35714285 with a remaining 3e-08.
