858869 ÷ 42 
We want to divide 858869 by 42.

Let's proceed to step 1:
The number 42 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 42

Going ahead to step 2:
85 divided by 42 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 84 from 85, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 42

Going ahead to step 3:
The number 42 fits into 18 0 times, leaving a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtracting 0 from 18 leaves us with 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 42

On to step 4:
188 divided by 42 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 204.0
Deduct 168 from 188 and we're left with 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 42

Going ahead to step 5:
42 goes into 206 4 times with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 2044.0
If we subtract 168 from 206, we get 38.
Bring next digit (9) of the dividend behind the 38 and repeat the process: 389 / 42

On to step 6:
The number 42 fits into 389 9 times, leaving a remainder of 11.
The next digit of our result is 9. 
Result so far: 20449.0
The remainder is 11 after subtracting 378 from 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
42 can be fit into 110 2 times, resulting in a remainder of 26.
The next digit of our result is 2. 
Result so far: 20449.2
If we subtract 84 from 110, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 20449.26
Deduct 252 from 260 and we're left 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.

Let's proceed to step 9:
42 can be fit into 80 1 times, resulting in a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 20449.261
Subtract 42 from 80 to get 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 10:
380 divided by 42 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 20449.2619
Subtracting 378 from 380 leaves us 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 11:
42 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 20449.2619
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.

Moving on to step 12:
If we divide 200 by 42, we get 4 and a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 20449.261904
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.

Moving on to step 13:
When dividing 320 by 42, we get 7 with a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 20449.2619047
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
The number 42 fits into 260 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 20449.26190476
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.

In conclusion, the division gives 20449.26190476 with a balance of 8e-09.
