We divide 17521463 by 842
We want to figure out the number of times 17521463 can be divided by 842.

Step 1:
The number 842 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 842

Let's proceed to step 2:
If we divide 17 by 842, we get 0 and a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 842

On to step 3:
When dividing 175 by 842, we get 0 with a remainder of 175.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 175 after subtracting 0 from 175.
Grab the next digit (2) from the dividend, add it to 175, then carry on: 1752 / 842

Step 4:
842 goes into 1752 2 times with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 68 after subtracting 1684 from 1752.
Take the next digit (1) from the dividend and append it to 68, then repeat: 681 / 842

On to step 5:
The number 842 fits into 681 0 times, leaving a remainder of 681.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
The remainder is 681 after subtracting 0 from 681.
Append the next digit (4) from the dividend to 681 and continue with: 6814 / 842

Moving on to step 6:
If we divide 6814 by 842, we get 8 and a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 208.0
If we take 6736 away from 6814, we end up with 78.
Bring next digit (6) of the dividend behind the 78 and repeat the process: 786 / 842

Advancing to step 7:
842 goes into 786 0 times with a remainder of 786.
Write down 0 as next digit of the result. 
Result so far: 2080.0
If we take 0 away from 786, we end up with 786.
Grab the next digit (3) from the dividend, add it to 786, then carry on: 7863 / 842

Let's proceed to step 8:
842 goes into 7863 9 times with a remainder of 285.
Record the quotient 9 as the next digit in the result. 
Result so far: 20809.0
If we subtract 7578 from 7863, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 9:
The number 842 fits into 2850 3 times, leaving a remainder of 324.
The number 3 becomes the next digit in our result. 
Result so far: 20809.3
Subtracting 2526 from 2850 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Moving on to step 10:
842 can be fit into 3240 3 times, resulting in a remainder of 714.
Record the quotient 3 as the next digit in the result. 
Result so far: 20809.33
Subtract 2526 from 3240 to get 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

The final outcome is 20809.33, with a leftover of 0.714.
