We're dividing 39301764 by 449 
We want to figure out the number of times 39301764 can be divided by 449.

On to step 1:
If we divide 3 by 449, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 449

Advancing to step 2:
449 can be fit into 39 0 times, resulting in a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 449

Step 3:
If we divide 393 by 449, we get 0 and a remainder of 393.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 393 to get 393.
Bring next digit (0) of the dividend behind the 393 and repeat the process: 3930 / 449

Step 4:
449 can be fit into 3930 8 times, resulting in a remainder of 338.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 3592 from 3930 leaves us with 338.
Fetch the next digit (1) from the dividend, attach it to 338 and continue: 3381 / 449

Step 5:
449 goes into 3381 7 times with a remainder of 238.
Use 7 as the next digit of our solution. 
Result so far: 87.0
If we take 3143 away from 3381, we end up with 238.
Take the next digit (7) from the dividend and append it to 238, then repeat: 2387 / 449

Going ahead to step 6:
When dividing 2387 by 449, we get 5 with a remainder of 142.
Put 5 as the next digit of the answer. 
Result so far: 875.0
If we subtract 2245 from 2387, we get 142.
Include the next digit (6) from the dividend after 142, then repeat: 1426 / 449

On to step 7:
449 goes into 1426 3 times with a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 8753.0
The remainder is 79 after subtracting 1347 from 1426.
Fetch the next digit (4) from the dividend, attach it to 79 and continue: 794 / 449

Going ahead to step 8:
The number 449 fits into 794 1 times, leaving a remainder of 345.
Put 1 as the next digit of the answer. 
Result so far: 87531.0
Subtracting 449 from 794 leaves us with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

On to step 9:
If we divide 3450 by 449, we get 7 and a remainder of 307.
Put 7 as the next digit of the answer. 
Result so far: 87531.7
Deduct 3143 from 3450 and we're left with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Moving on to step 10:
3070 divided by 449 is 6 with a remainder of 376.
Use 6 as the next digit of our solution. 
Result so far: 87531.76
Subtract 2694 from 3070 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 11:
449 goes into 3760 8 times with a remainder of 168.
The number 8 becomes the next digit in our result. 
Result so far: 87531.768
Deduct 3592 from 3760 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 12:
449 can be fit into 1680 3 times, resulting in a remainder of 333.
Put 3 as the next digit of the answer. 
Result so far: 87531.7683
Subtracting 1347 from 1680 leaves us with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Advancing to step 13:
449 can be fit into 3330 7 times, resulting in a remainder of 187.
Write down 7 as next digit of the result. 
Result so far: 87531.76837
If we take 3143 away from 3330, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Going ahead to step 14:
449 goes into 1870 4 times with a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 87531.768374
If we subtract 1796 from 1870, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 15:
The number 449 fits into 740 1 times, leaving a remainder of 291.
The next digit of our result is 1. 
Result so far: 87531.7683741
If we subtract 449 from 740, we get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Going ahead to step 16:
449 can be fit into 2910 6 times, resulting in a remainder of 216.
The number 6 becomes the next digit in our result. 
Result so far: 87531.76837416
The remainder is 216 after subtracting 2694 from 2910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

The final outcome is 87531.76837416, with a leftover of 2.16e-07.
