84749387 ÷ 449 
We want to figure out the number of times 84749387 can be divided by 449.

On to step 1:
449 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 449

Moving on to step 2:
449 goes into 84 0 times with a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Include the next digit (7) from the dividend after 84, then repeat: 847 / 449

Let's proceed to step 3:
If we divide 847 by 449, we get 1 and a remainder of 398.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 449 from 847 leaves us with 398.
Take the next digit (4) from the dividend and append it to 398, then repeat: 3984 / 449

Moving on to step 4:
449 goes into 3984 8 times with a remainder of 392.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we subtract 3592 from 3984, we get 392.
Bring next digit (9) of the dividend behind the 392 and repeat the process: 3929 / 449

Advancing to step 5:
449 goes into 3929 8 times with a remainder of 337.
The next digit of our result is 8. 
Result so far: 188.0
Subtract 3592 from 3929 to get 337.
Fetch the next digit (3) from the dividend, attach it to 337 and continue: 3373 / 449

On to step 6:
3373 divided by 449 is 7 with a remainder of 230.
The next digit of our result is 7. 
Result so far: 1887.0
The remainder is 230 after subtracting 3143 from 3373.
Bring next digit (8) of the dividend behind the 230 and repeat the process: 2308 / 449

Step 7:
If we divide 2308 by 449, we get 5 and a remainder of 63.
The next digit of our result is 5. 
Result so far: 18875.0
If we take 2245 away from 2308, we end up with 63.
Include the next digit (7) from the dividend after 63, then repeat: 637 / 449

Advancing to step 8:
449 goes into 637 1 times with a remainder of 188.
The number 1 becomes the next digit in our result. 
Result so far: 188751.0
Deduct 449 from 637 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 9:
When dividing 1880 by 449, we get 4 with a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 188751.4
The remainder is 84 after subtracting 1796 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 10:
When dividing 840 by 449, we get 1 with a remainder of 391.
The next digit of our result is 1. 
Result so far: 188751.41
Subtracting 449 from 840 leaves us with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 11:
The number 449 fits into 3910 8 times, leaving a remainder of 318.
Put 8 as the next digit of the answer. 
Result so far: 188751.418
If we subtract 3592 from 3910, we get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Step 12:
3180 divided by 449 is 7 with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 188751.4187
Subtracting 3143 from 3180 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 13:
370 divided by 449 is 0 with a remainder of 370.
The next digit of our result is 0. 
Result so far: 188751.4187
If we subtract 0 from 370, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 14:
The number 449 fits into 3700 8 times, leaving a remainder of 108.
Write down 8 as next digit of the result. 
Result so far: 188751.418708
Deduct 3592 from 3700 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 15:
If we divide 1080 by 449, we get 2 and a remainder of 182.
Write down 2 as next digit of the result. 
Result so far: 188751.4187082
If we take 898 away from 1080, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 16:
449 goes into 1820 4 times with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 188751.41870824
Subtract 1796 from 1820 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 188751.41870824, with a leftover of 2.4e-08.
