Let's divide 810220 by 42
Let's see how many times 42 fits into 810220.

Let's proceed to step 1:
When dividing 8 by 42, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 42

Advancing to step 2:
The number 42 fits into 81 1 times, leaving a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 42 from 81 leaves us with 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 42

Going ahead to step 3:
42 goes into 390 9 times with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 12 after subtracting 378 from 390.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 42

Step 4:
42 goes into 122 2 times with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 192.0
If we subtract 84 from 122, we get 38.
Append the next digit (2) from the dividend to 38 and continue with: 382 / 42

On to step 5:
42 goes into 382 9 times with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 1929.0
Subtracting 378 from 382 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 42

Going ahead to step 6:
When dividing 40 by 42, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 19290.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 19290.9
Deduct 378 from 400 and we're left 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.

Moving on to step 8:
42 can be fit into 220 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 19290.95
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 9:
If we divide 100 by 42, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 19290.952
If we take 84 away from 100, we end up 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.

Moving on to step 10:
160 divided by 42 is 3 with a remainder of 34.
The next digit of our result is 3. 
Result so far: 19290.9523
The remainder is 34 after subtracting 126 from 160.
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 11:
340 divided by 42 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 19290.95238
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 12:
40 divided by 42 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 19290.95238
If we subtract 0 from 40, we 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.

Moving on to step 13:
42 goes into 400 9 times with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 19290.9523809
Deduct 378 from 400 and we're left 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.

On to step 14:
The number 42 fits into 220 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 19290.95238095
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.

After the division, we end up with 19290.95238095 and a remainder of 1e-08.
