852791 divided by 42 
Let's see how many times 42 fits into 852791.

Advancing to step 1:
42 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 42

Step 2:
The number 42 fits into 85 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 84 from 85, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 42

Let's proceed to step 3:
The number 42 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 42

Advancing to step 4:
The number 42 fits into 127 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 203.0
If we subtract 126 from 127, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 42

Advancing to step 5:
The number 42 fits into 19 0 times, leaving a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 2030.0
If we take 0 away from 19, we end up with 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 42

Going ahead to step 6:
42 can be fit into 191 4 times, resulting in a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 20304.0
Subtracting 168 from 191 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
The number 42 fits into 230 5 times, leaving a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 20304.5
Deduct 210 from 230 and we're left 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.

Going ahead to step 8:
If we divide 200 by 42, we get 4 and a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 20304.54
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.

Let's proceed to step 9:
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: 20304.547
If we take 294 away from 320, we end up 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.

On to step 10:
42 goes into 260 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 20304.5476
If we subtract 252 from 260, we 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.

On to step 11:
If we divide 80 by 42, we get 1 and a remainder of 38.
The next digit of our result is 1. 
Result so far: 20304.54761
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.

Advancing to step 12:
380 divided by 42 is 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 20304.547619
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.

Step 13:
The number 42 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 20304.547619
If we take 0 away from 20, we end up 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 14:
The number 42 fits into 200 4 times, leaving a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 20304.54761904
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.

The final outcome is 20304.54761904, with a leftover of 3.2e-08.
