849666 divided by 42 
We want to figure out the number of times 849666 can be divided by 42.

Let's proceed to step 1:
If we divide 8 by 42, we get 0 and 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.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 42

Let's proceed to step 2:
The number 42 fits into 84 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 84 from 84 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 42

Step 3:
42 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 9, we get 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 42

On to step 4:
96 divided by 42 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 202.0
If we subtract 84 from 96, we get 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 42

Moving on to step 5:
If we divide 126 by 42, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 2023.0
If we take 126 away from 126, we end up with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 42

On to step 6:
6 divided by 42 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 20230.0
If we subtract 0 from 6, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
When dividing 60 by 42, we get 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 20230.1
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
180 divided by 42 is 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 20230.14
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 20230.142
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
42 goes into 360 8 times with a remainder of 24.
The next digit of our result is 8. 
Result so far: 20230.1428
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
42 can be fit into 240 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 20230.14285
Deduct 210 from 240 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 20230.142857
If we take 294 away from 300, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 20230.1428571
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 14:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 20230.14285714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 20230.14285714, and the remainder is 1.2e-08.
