879959 divided by 42 
We want to figure out the number of times 879959 can be divided by 42.

Let's proceed to step 1:
If we divide 8 by 42, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 42

On to step 2:
42 goes into 87 2 times with a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 84 from 87 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 42

Let's proceed to step 3:
If we divide 39 by 42, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 42

Advancing to step 4:
If we divide 399 by 42, we get 9 and a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 209.0
The remainder is 21 after subtracting 378 from 399.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 42

Step 5:
When dividing 215 by 42, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 2095.0
The remainder is 5 after subtracting 210 from 215.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 42

Advancing to step 6:
When dividing 59 by 42, we get 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 20951.0
If we take 42 away from 59, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
The number 42 fits into 170 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 20951.4
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
When dividing 20 by 42, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 20951.4
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
The number 42 fits into 200 4 times, leaving a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 20951.404
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
The number 42 fits into 320 7 times, leaving a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 20951.4047
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.

Let's proceed to step 11:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 20951.40476
If we take 252 away from 260, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
42 goes into 80 1 times with a remainder of 38.
The next digit of our result is 1. 
Result so far: 20951.404761
Subtracting 42 from 80 leaves us 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.

Moving on to step 13:
When dividing 380 by 42, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 20951.4047619
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
The number 42 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 20951.4047619
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 20951.4047619 with a balance of 2e-08.
