42341711 ÷ 803 
Our goal is to divide 42341711 by 803.

On to step 1:
If we divide 4 by 803, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 803

Let's proceed to step 2:
If we divide 42 by 803, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 803

Advancing to step 3:
The number 803 fits into 423 0 times, leaving a remainder of 423.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 423 after subtracting 0 from 423.
Bring next digit (4) of the dividend behind the 423 and repeat the process: 4234 / 803

On to step 4:
If we divide 4234 by 803, we get 5 and a remainder of 219.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 4015 from 4234, we get 219.
Include the next digit (1) from the dividend after 219, then repeat: 2191 / 803

Step 5:
803 can be fit into 2191 2 times, resulting in a remainder of 585.
Use 2 as the next digit of our solution. 
Result so far: 52.0
If we take 1606 away from 2191, we end up with 585.
Take the next digit (7) from the dividend and append it to 585, then repeat: 5857 / 803

Let's proceed to step 6:
5857 divided by 803 is 7 with a remainder of 236.
Record the quotient 7 as the next digit in the result. 
Result so far: 527.0
If we subtract 5621 from 5857, we get 236.
Append the next digit (1) from the dividend to 236 and continue with: 2361 / 803

Let's proceed to step 7:
If we divide 2361 by 803, we get 2 and a remainder of 755.
The number 2 becomes the next digit in our result. 
Result so far: 5272.0
The remainder is 755 after subtracting 1606 from 2361.
Grab the next digit (1) from the dividend, add it to 755, then carry on: 7551 / 803

Step 8:
The number 803 fits into 7551 9 times, leaving a remainder of 324.
The number 9 becomes the next digit in our result. 
Result so far: 52729.0
Subtracting 7227 from 7551 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.

Step 9:
803 goes into 3240 4 times with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 52729.4
The remainder is 28 after subtracting 3212 from 3240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
The number 803 fits into 280 0 times, leaving a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 52729.4
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 11:
803 goes into 2800 3 times with a remainder of 391.
Use 3 as the next digit of our solution. 
Result so far: 52729.403
Subtract 2409 from 2800 to get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Step 12:
The number 803 fits into 3910 4 times, leaving a remainder of 698.
Write down 4 as next digit of the result. 
Result so far: 52729.4034
If we subtract 3212 from 3910, we get 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Advancing to step 13:
The number 803 fits into 6980 8 times, leaving a remainder of 556.
The next digit of our result is 8. 
Result so far: 52729.40348
Subtract 6424 from 6980 to get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Step 14:
If we divide 5560 by 803, we get 6 and a remainder of 742.
The number 6 becomes the next digit in our result. 
Result so far: 52729.403486
The remainder is 742 after subtracting 4818 from 5560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

On to step 15:
803 goes into 7420 9 times with a remainder of 193.
Put 9 as the next digit of the answer. 
Result so far: 52729.4034869
If we subtract 7227 from 7420, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

On to step 16:
When dividing 1930 by 803, we get 2 with a remainder of 324.
The number 2 becomes the next digit in our result. 
Result so far: 52729.40348692
The remainder is 324 after subtracting 1606 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Our division results in 52729.40348692 with a remaining 3.24e-07.
