We look at the division of 42731213 by 817 
We're looking to find how many times 817 goes into 42731213.

Advancing to step 1:
When dividing 4 by 817, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 817

Step 2:
817 goes into 42 0 times with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 817

On to step 3:
817 goes into 427 0 times with a remainder of 427.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 427 leaves us with 427.
Bring next digit (3) of the dividend behind the 427 and repeat the process: 4273 / 817

Advancing to step 4:
When dividing 4273 by 817, we get 5 with a remainder of 188.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 4085 away from 4273, we end up with 188.
Grab the next digit (1) from the dividend, add it to 188, then carry on: 1881 / 817

Let's proceed to step 5:
If we divide 1881 by 817, we get 2 and a remainder of 247.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
Subtract 1634 from 1881 to get 247.
Append the next digit (2) from the dividend to 247 and continue with: 2472 / 817

Moving on to step 6:
When dividing 2472 by 817, we get 3 with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 523.0
If we take 2451 away from 2472, we end up with 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 817

Moving on to step 7:
211 divided by 817 is 0 with a remainder of 211.
Record the quotient 0 as the next digit in the result. 
Result so far: 5230.0
If we subtract 0 from 211, we get 211.
Append the next digit (3) from the dividend to 211 and continue with: 2113 / 817

On to step 8:
If we divide 2113 by 817, we get 2 and a remainder of 479.
Put 2 as the next digit of the answer. 
Result so far: 52302.0
If we take 1634 away from 2113, we end up with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Step 9:
817 can be fit into 4790 5 times, resulting in a remainder of 705.
Use 5 as the next digit of our solution. 
Result so far: 52302.5
If we subtract 4085 from 4790, we get 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Going ahead to step 10:
817 can be fit into 7050 8 times, resulting in a remainder of 514.
Put 8 as the next digit of the answer. 
Result so far: 52302.58
If we subtract 6536 from 7050, we get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Going ahead to step 11:
The number 817 fits into 5140 6 times, leaving a remainder of 238.
Put 6 as the next digit of the answer. 
Result so far: 52302.586
Subtracting 4902 from 5140 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 12:
817 goes into 2380 2 times with a remainder of 746.
Put 2 as the next digit of the answer. 
Result so far: 52302.5862
Subtracting 1634 from 2380 leaves us with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Moving on to step 13:
817 can be fit into 7460 9 times, resulting in a remainder of 107.
The number 9 becomes the next digit in our result. 
Result so far: 52302.58629
Subtracting 7353 from 7460 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Advancing to step 14:
1070 divided by 817 is 1 with a remainder of 253.
The number 1 becomes the next digit in our result. 
Result so far: 52302.586291
Deduct 817 from 1070 and we're left with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

On to step 15:
817 can be fit into 2530 3 times, resulting in a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 52302.5862913
The remainder is 79 after subtracting 2451 from 2530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 16:
When dividing 790 by 817, we get 0 with a remainder of 790.
The next digit of our result is 0. 
Result so far: 52302.5862913
Deduct 0 from 790 and we're left with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

The final outcome is 52302.5862913, with a leftover of 7.9e-07.
