853490 ÷ 42 
We want to divide 853490 by 42.

Advancing to step 1:
42 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 42

Going ahead to step 2:
42 goes into 85 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 1 after subtracting 84 from 85.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 42

Step 3:
If we divide 13 by 42, we get 0 and a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we take 0 away from 13, we end up with 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 42

Advancing to step 4:
42 goes into 134 3 times with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 203.0
The remainder is 8 after subtracting 126 from 134.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 42

On to step 5:
If we divide 89 by 42, we get 2 and a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2032.0
The remainder is 5 after subtracting 84 from 89.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 42

On to step 6:
42 goes into 50 1 times with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 20321.0
Subtract 42 from 50 to get 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 7:
If we divide 80 by 42, we get 1 and a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 20321.1
Deduct 42 from 80 and we're left 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.

Going ahead to step 8:
42 goes into 380 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 20321.19
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 9:
If we divide 20 by 42, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 20321.19
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
42 goes into 200 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 20321.1904
If we take 168 away from 200, we end up 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 11:
When dividing 320 by 42, we get 7 with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 20321.19047
Subtract 294 from 320 to 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.

Advancing to step 12:
42 goes into 260 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 20321.190476
Subtracting 252 from 260 leaves us 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 13:
80 divided by 42 is 1 with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 20321.1904761
Deduct 42 from 80 and we're left 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.

On to step 14:
The number 42 fits into 380 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 20321.19047619
Subtract 378 from 380 to 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.

Our division results in 20321.19047619 with a remaining 2e-09.
