We look at the division of 863236 by 42 
We want to figure out the number of times 863236 can be divided by 42.

Advancing to step 1:
8 divided by 42 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 42

Advancing to step 2:
42 goes into 86 2 times 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.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 42

On to step 3:
42 goes into 23 0 times with a remainder of 23.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 23, we end up with 23.
Take the next digit (2) from the dividend and append it to 23, then repeat: 232 / 42

Advancing to step 4:
If we divide 232 by 42, we get 5 and a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 205.0
Subtracting 210 from 232 leaves us with 22.
Take the next digit (3) from the dividend and append it to 22, then repeat: 223 / 42

Going ahead to step 5:
The number 42 fits into 223 5 times, leaving a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 2055.0
Subtracting 210 from 223 leaves us with 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 42

Going ahead to step 6:
When dividing 136 by 42, we get 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 20553.0
Deduct 126 from 136 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 20553.2
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
If we divide 160 by 42, we get 3 and a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 20553.23
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 20553.238
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
42 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 20553.238
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
The number 42 fits into 400 9 times, leaving a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 20553.23809
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
42 can be fit into 220 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 20553.238095
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
If we divide 100 by 42, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 20553.2380952
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
42 goes into 160 3 times with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 20553.23809523
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 20553.23809523 with a balance of 3.4e-08.
