When dividing 1 by 742, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 742

On to step 2:
When dividing 12 by 742, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 742

Going ahead to step 3:
742 goes into 122 0 times with a remainder of 122.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 122 after subtracting 0 from 122.
Include the next digit (2) from the dividend after 122, then repeat: 1222 / 742

Advancing to step 4:
The number 742 fits into 1222 1 times, leaving a remainder of 480.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 742 from 1222 to get 480.
Fetch the next digit (1) from the dividend, attach it to 480 and continue: 4801 / 742

Moving on to step 5:
742 can be fit into 4801 6 times, resulting in a remainder of 349.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 349 after subtracting 4452 from 4801.
Fetch the next digit (2) from the dividend, attach it to 349 and continue: 3492 / 742

Step 6:
When dividing 3492 by 742, we get 4 with a remainder of 524.
Use 4 as the next digit of our solution. 
Result so far: 164.0
Subtracting 2968 from 3492 leaves us with 524.
Fetch the next digit (1) from the dividend, attach it to 524 and continue: 5241 / 742

Going ahead to step 7:
5241 divided by 742 is 7 with a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 1647.0
Deduct 5194 from 5241 and we're left with 47.
Fetch the next digit (6) from the dividend, attach it to 47 and continue: 476 / 742

Let's proceed to step 8:
476 divided by 742 is 0 with a remainder of 476.
The number 0 becomes the next digit in our result. 
Result so far: 16470.0
Subtracting 0 from 476 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 9:
The number 742 fits into 4760 6 times, leaving a remainder of 308.
Write down 6 as next digit of the result. 
Result so far: 16470.6
Subtract 4452 from 4760 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 10:
When dividing 3080 by 742, we get 4 with a remainder of 112.
Use 4 as the next digit of our solution. 
Result so far: 16470.64
Subtracting 2968 from 3080 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 11:
If we divide 1120 by 742, we get 1 and a remainder of 378.
Write down 1 as next digit of the result. 
Result so far: 16470.641
Subtract 742 from 1120 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Advancing to step 12:
The number 742 fits into 3780 5 times, leaving a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 16470.6415
Subtracting 3710 from 3780 leaves us 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.

Going ahead to step 13:
742 can be fit into 700 0 times, resulting in a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 16470.6415
Subtracting 0 from 700 leaves us 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 14:
The number 742 fits into 7000 9 times, leaving a remainder of 322.
The number 9 becomes the next digit in our result. 
Result so far: 16470.641509
Deduct 6678 from 7000 and we're left with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Let's proceed to step 15:
742 goes into 3220 4 times with a remainder of 252.
Use 4 as the next digit of our solution. 
Result so far: 16470.6415094
The remainder is 252 after subtracting 2968 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 16:
2520 divided by 742 is 3 with a remainder of 294.
The next digit of our result is 3. 
Result so far: 16470.64150943
Subtract 2226 from 2520 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

The quotient of the division is 16470.64150943, and the remainder is 2.94e-07.
