We're dividing 39946453 by 744 
We want to divide 39946453 by 744.

Step 1:
3 divided by 744 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 744

Let's proceed to step 2:
When dividing 39 by 744, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 744

Step 3:
When dividing 399 by 744, we get 0 with a remainder of 399.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 399 leaves us with 399.
Append the next digit (4) from the dividend to 399 and continue with: 3994 / 744

Step 4:
When dividing 3994 by 744, we get 5 with a remainder of 274.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 3720 from 3994 and we're left with 274.
Append the next digit (6) from the dividend to 274 and continue with: 2746 / 744

Moving on to step 5:
2746 divided by 744 is 3 with a remainder of 514.
Write down 3 as next digit of the result. 
Result so far: 53.0
If we take 2232 away from 2746, we end up with 514.
Grab the next digit (4) from the dividend, add it to 514, then carry on: 5144 / 744

Step 6:
When dividing 5144 by 744, we get 6 with a remainder of 680.
The number 6 becomes the next digit in our result. 
Result so far: 536.0
Subtract 4464 from 5144 to get 680.
Take the next digit (5) from the dividend and append it to 680, then repeat: 6805 / 744

Step 7:
If we divide 6805 by 744, we get 9 and a remainder of 109.
The number 9 becomes the next digit in our result. 
Result so far: 5369.0
If we take 6696 away from 6805, we end up with 109.
Include the next digit (3) from the dividend after 109, then repeat: 1093 / 744

Let's proceed to step 8:
1093 divided by 744 is 1 with a remainder of 349.
Put 1 as the next digit of the answer. 
Result so far: 53691.0
If we subtract 744 from 1093, we get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Advancing to step 9:
3490 divided by 744 is 4 with a remainder of 514.
Put 4 as the next digit of the answer. 
Result so far: 53691.4
Subtract 2976 from 3490 to get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

On to step 10:
5140 divided by 744 is 6 with a remainder of 676.
The number 6 becomes the next digit in our result. 
Result so far: 53691.46
If we subtract 4464 from 5140, we get 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Advancing to step 11:
744 can be fit into 6760 9 times, resulting in a remainder of 64.
Record the quotient 9 as the next digit in the result. 
Result so far: 53691.469
If we take 6696 away from 6760, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 12:
640 divided by 744 is 0 with a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 53691.469
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 13:
If we divide 6400 by 744, we get 8 and a remainder of 448.
The next digit of our result is 8. 
Result so far: 53691.46908
If we take 5952 away from 6400, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 14:
4480 divided by 744 is 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 53691.469086
Subtract 4464 from 4480 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 15:
The number 744 fits into 160 0 times, leaving a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 53691.469086
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 16:
When dividing 1600 by 744, we get 2 with a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 53691.46908602
The remainder is 112 after subtracting 1488 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

After the division, we end up with 53691.46908602 and a remainder of 1.12e-07.
