We're dividing 856696 by 42 
Let's see how many times 42 fits into 856696.

Step 1:
8 divided by 42 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 42

Let's proceed to step 2:
When dividing 85 by 42, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 84 from 85 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 42

Let's proceed to step 3:
If we divide 16 by 42, we get 0 and a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we take 0 away from 16, we end up with 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 42

Going ahead to step 4:
If we divide 166 by 42, we get 3 and a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 203.0
Subtracting 126 from 166 leaves us with 40.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 42

Let's proceed to step 5:
When dividing 409 by 42, we get 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 2039.0
Deduct 378 from 409 and we're left with 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 42

Advancing to step 6:
42 goes into 316 7 times with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 20397.0
Subtract 294 from 316 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
If we divide 220 by 42, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 20397.5
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.

Moving on to step 8:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 20397.52
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
The number 42 fits into 160 3 times, leaving a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 20397.523
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
340 divided by 42 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 20397.5238
If we take 336 away from 340, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
40 divided by 42 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 20397.5238
If we take 0 away from 40, we end up 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.

Step 12:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 20397.523809
Subtracting 378 from 400 leaves us 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.

Step 13:
The number 42 fits into 220 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 20397.5238095
Deduct 210 from 220 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 14:
When dividing 100 by 42, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 20397.52380952
Subtracting 84 from 100 leaves us 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.

After the division, we end up with 20397.52380952 and a remainder of 1.6e-08.
