850513 divided by 42 
Let's see how many times 42 fits into 850513.

Going ahead to step 1:
8 divided by 42 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 42

Moving on to step 2:
42 goes into 85 2 times with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 84 from 85 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 42

Going ahead to step 3:
If we divide 10 by 42, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 20.0
The remainder is 10 after subtracting 0 from 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 42

Moving on to step 4:
105 divided by 42 is 2 with a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 202.0
Deduct 84 from 105 and we're left with 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 42

On to step 5:
When dividing 211 by 42, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 2025.0
Deduct 210 from 211 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 42

On to step 6:
If we divide 13 by 42, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 20250.0
If we subtract 0 from 13, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
If we divide 130 by 42, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 20250.3
Deduct 126 from 130 and we're left 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.

Moving on to step 8:
40 divided by 42 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 20250.3
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
42 goes into 400 9 times with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 20250.309
The remainder is 22 after subtracting 378 from 400.
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 10:
When dividing 220 by 42, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 20250.3095
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
42 goes into 100 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 20250.30952
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.

On to step 12:
160 divided by 42 is 3 with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 20250.309523
Subtracting 126 from 160 leaves us 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.

Let's proceed to step 13:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 20250.3095238
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.

Going ahead to step 14:
42 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 20250.3095238
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.

After the division, we end up with 20250.3095238 and a remainder of 4e-08.
