We divide 42660166 by 817
Let's see how many times 817 fits into 42660166.

Let's proceed to step 1:
817 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 817

Step 2:
The number 817 fits into 42 0 times, leaving a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 817

Moving on to step 3:
If we divide 426 by 817, we get 0 and a remainder of 426.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 426 leaves us with 426.
Append the next digit (6) from the dividend to 426 and continue with: 4266 / 817

Going ahead to step 4:
817 goes into 4266 5 times with a remainder of 181.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 4085 away from 4266, we end up with 181.
Take the next digit (0) from the dividend and append it to 181, then repeat: 1810 / 817

On to step 5:
The number 817 fits into 1810 2 times, leaving a remainder of 176.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Deduct 1634 from 1810 and we're left with 176.
Fetch the next digit (1) from the dividend, attach it to 176 and continue: 1761 / 817

On to step 6:
1761 divided by 817 is 2 with a remainder of 127.
Write down 2 as next digit of the result. 
Result so far: 522.0
If we subtract 1634 from 1761, we get 127.
Fetch the next digit (6) from the dividend, attach it to 127 and continue: 1276 / 817

Step 7:
817 goes into 1276 1 times with a remainder of 459.
Write down 1 as next digit of the result. 
Result so far: 5221.0
Subtracting 817 from 1276 leaves us with 459.
Append the next digit (6) from the dividend to 459 and continue with: 4596 / 817

Going ahead to step 8:
The number 817 fits into 4596 5 times, leaving a remainder of 511.
Write down 5 as next digit of the result. 
Result so far: 52215.0
Subtract 4085 from 4596 to get 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

On to step 9:
817 goes into 5110 6 times with a remainder of 208.
Put 6 as the next digit of the answer. 
Result so far: 52215.6
If we subtract 4902 from 5110, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 10:
When dividing 2080 by 817, we get 2 with a remainder of 446.
Use 2 as the next digit of our solution. 
Result so far: 52215.62
If we take 1634 away from 2080, we end up with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Step 11:
817 can be fit into 4460 5 times, resulting in a remainder of 375.
The next digit of our result is 5. 
Result so far: 52215.625
If we take 4085 away from 4460, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 12:
3750 divided by 817 is 4 with a remainder of 482.
The number 4 becomes the next digit in our result. 
Result so far: 52215.6254
The remainder is 482 after subtracting 3268 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Step 13:
The number 817 fits into 4820 5 times, leaving a remainder of 735.
Write down 5 as next digit of the result. 
Result so far: 52215.62545
Subtract 4085 from 4820 to get 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Moving on to step 14:
817 goes into 7350 8 times with a remainder of 814.
Write down 8 as next digit of the result. 
Result so far: 52215.625458
Deduct 6536 from 7350 and we're left with 814.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8140, and continue the process.

Moving on to step 15:
817 goes into 8140 9 times with a remainder of 787.
Use 9 as the next digit of our solution. 
Result so far: 52215.6254589
If we subtract 7353 from 8140, we get 787.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7870, and continue the process.

Going ahead to step 16:
817 can be fit into 7870 9 times, resulting in a remainder of 517.
Write down 9 as next digit of the result. 
Result so far: 52215.62545899
If we subtract 7353 from 7870, we get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

The final result is 52215.62545899 with a remainder of 5.17e-07.
