42127834 ÷ 817 
Our goal is to divide 42127834 by 817.

Moving on to step 1:
817 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 817

Going ahead to step 2:
817 can be fit into 42 0 times, resulting in 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.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 817

Step 3:
The number 817 fits into 421 0 times, leaving a remainder of 421.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 421 leaves us with 421.
Append the next digit (2) from the dividend to 421 and continue with: 4212 / 817

On to step 4:
When dividing 4212 by 817, we get 5 with a remainder of 127.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 4085 from 4212, we get 127.
Grab the next digit (7) from the dividend, add it to 127, then carry on: 1277 / 817

Advancing to step 5:
If we divide 1277 by 817, we get 1 and a remainder of 460.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtract 817 from 1277 to get 460.
Take the next digit (8) from the dividend and append it to 460, then repeat: 4608 / 817

Step 6:
4608 divided by 817 is 5 with a remainder of 523.
The number 5 becomes the next digit in our result. 
Result so far: 515.0
Subtract 4085 from 4608 to get 523.
Fetch the next digit (3) from the dividend, attach it to 523 and continue: 5233 / 817

On to step 7:
5233 divided by 817 is 6 with a remainder of 331.
Write down 6 as next digit of the result. 
Result so far: 5156.0
Subtracting 4902 from 5233 leaves us with 331.
Bring next digit (4) of the dividend behind the 331 and repeat the process: 3314 / 817

On to step 8:
817 can be fit into 3314 4 times, resulting in a remainder of 46.
The next digit of our result is 4. 
Result so far: 51564.0
Subtracting 3268 from 3314 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 9:
817 goes into 460 0 times with a remainder of 460.
Use 0 as the next digit of our solution. 
Result so far: 51564.0
Subtract 0 from 460 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 10:
4600 divided by 817 is 5 with a remainder of 515.
The number 5 becomes the next digit in our result. 
Result so far: 51564.05
If we subtract 4085 from 4600, we get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Advancing to step 11:
817 can be fit into 5150 6 times, resulting in a remainder of 248.
Record the quotient 6 as the next digit in the result. 
Result so far: 51564.056
Deduct 4902 from 5150 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 12:
2480 divided by 817 is 3 with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 51564.0563
Subtract 2451 from 2480 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 13:
817 goes into 290 0 times with a remainder of 290.
The next digit of our result is 0. 
Result so far: 51564.0563
Subtracting 0 from 290 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 14:
817 goes into 2900 3 times with a remainder of 449.
The number 3 becomes the next digit in our result. 
Result so far: 51564.056303
Subtracting 2451 from 2900 leaves us with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Step 15:
The number 817 fits into 4490 5 times, leaving a remainder of 405.
Put 5 as the next digit of the answer. 
Result so far: 51564.0563035
If we take 4085 away from 4490, we end up with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Step 16:
The number 817 fits into 4050 4 times, leaving a remainder of 782.
Use 4 as the next digit of our solution. 
Result so far: 51564.05630354
If we take 3268 away from 4050, we end up with 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Our division results in 51564.05630354 with a remaining 7.82e-07.
