342636 ÷ 745 
Our goal is to divide 342636 by 745.

Step 1:
The number 745 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 745

Let's proceed to step 2:
The number 745 fits into 34 0 times, leaving a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 745

On to step 3:
When dividing 342 by 745, we get 0 with a remainder of 342.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 342 and we're left with 342.
Include the next digit (6) from the dividend after 342, then repeat: 3426 / 745

Step 4:
The number 745 fits into 3426 4 times, leaving a remainder of 446.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 446 after subtracting 2980 from 3426.
Grab the next digit (3) from the dividend, add it to 446, then carry on: 4463 / 745

Going ahead to step 5:
4463 divided by 745 is 5 with a remainder of 738.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtract 3725 from 4463 to get 738.
Append the next digit (6) from the dividend to 738 and continue with: 7386 / 745

Moving on to step 6:
745 goes into 7386 9 times with a remainder of 681.
Record the quotient 9 as the next digit in the result. 
Result so far: 459.0
If we subtract 6705 from 7386, we get 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

Advancing to step 7:
If we divide 6810 by 745, we get 9 and a remainder of 105.
Record the quotient 9 as the next digit in the result. 
Result so far: 459.9
The remainder is 105 after subtracting 6705 from 6810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 8:
745 goes into 1050 1 times with a remainder of 305.
Put 1 as the next digit of the answer. 
Result so far: 459.91
If we take 745 away from 1050, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 9:
The number 745 fits into 3050 4 times, leaving a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 459.914
Deduct 2980 from 3050 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
If we divide 700 by 745, we get 0 and a remainder of 700.
Write down 0 as next digit of the result. 
Result so far: 459.914
If we take 0 away from 700, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 11:
The number 745 fits into 7000 9 times, leaving a remainder of 295.
Use 9 as the next digit of our solution. 
Result so far: 459.91409
Subtracting 6705 from 7000 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 12:
The number 745 fits into 2950 3 times, leaving a remainder of 715.
Use 3 as the next digit of our solution. 
Result so far: 459.914093
Subtract 2235 from 2950 to get 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

On to step 13:
745 goes into 7150 9 times with a remainder of 445.
The next digit of our result is 9. 
Result so far: 459.9140939
Subtract 6705 from 7150 to get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Step 14:
4450 divided by 745 is 5 with a remainder of 725.
Use 5 as the next digit of our solution. 
Result so far: 459.91409395
Subtracting 3725 from 4450 leaves us with 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

After the division, we end up with 459.91409395 and a remainder of 7.25e-07.
