42109381 divided by 723 
We want to figure out the number of times 42109381 can be divided by 723.

Going ahead to step 1:
If we divide 4 by 723, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 723

Going ahead to step 2:
723 goes into 42 0 times with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 723

Step 3:
When dividing 421 by 723, we get 0 with a remainder of 421.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 421, we end up with 421.
Include the next digit (0) from the dividend after 421, then repeat: 4210 / 723

Going ahead to step 4:
723 can be fit into 4210 5 times, resulting in a remainder of 595.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 3615 from 4210 leaves us with 595.
Bring next digit (9) of the dividend behind the 595 and repeat the process: 5959 / 723

On to step 5:
The number 723 fits into 5959 8 times, leaving a remainder of 175.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
Subtracting 5784 from 5959 leaves us with 175.
Append the next digit (3) from the dividend to 175 and continue with: 1753 / 723

On to step 6:
1753 divided by 723 is 2 with a remainder of 307.
The number 2 becomes the next digit in our result. 
Result so far: 582.0
Subtracting 1446 from 1753 leaves us with 307.
Append the next digit (8) from the dividend to 307 and continue with: 3078 / 723

Step 7:
723 can be fit into 3078 4 times, resulting in a remainder of 186.
Use 4 as the next digit of our solution. 
Result so far: 5824.0
Subtract 2892 from 3078 to get 186.
Include the next digit (1) from the dividend after 186, then repeat: 1861 / 723

Going ahead to step 8:
The number 723 fits into 1861 2 times, leaving a remainder of 415.
The number 2 becomes the next digit in our result. 
Result so far: 58242.0
Subtract 1446 from 1861 to get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

On to step 9:
4150 divided by 723 is 5 with a remainder of 535.
Write down 5 as next digit of the result. 
Result so far: 58242.5
If we take 3615 away from 4150, we end up with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Let's proceed to step 10:
723 can be fit into 5350 7 times, resulting in a remainder of 289.
Record the quotient 7 as the next digit in the result. 
Result so far: 58242.57
The remainder is 289 after subtracting 5061 from 5350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

On to step 11:
723 goes into 2890 3 times with a remainder of 721.
Put 3 as the next digit of the answer. 
Result so far: 58242.573
Subtracting 2169 from 2890 leaves us with 721.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7210, and continue the process.

Going ahead to step 12:
723 goes into 7210 9 times with a remainder of 703.
Use 9 as the next digit of our solution. 
Result so far: 58242.5739
If we subtract 6507 from 7210, we get 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

Advancing to step 13:
7030 divided by 723 is 9 with a remainder of 523.
The next digit of our result is 9. 
Result so far: 58242.57399
Subtract 6507 from 7030 to get 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

The quotient of the division is 58242.57399, and the remainder is 0.000523.
