78634800 ÷ 449 
We want to figure out the number of times 78634800 can be divided by 449.

Let's proceed to step 1:
449 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 449

Going ahead to step 2:
449 goes into 78 0 times with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 449

Moving on to step 3:
The number 449 fits into 786 1 times, leaving a remainder of 337.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 449 from 786, we get 337.
Grab the next digit (3) from the dividend, add it to 337, then carry on: 3373 / 449

Step 4:
If we divide 3373 by 449, we get 7 and a remainder of 230.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 3143 from 3373 to get 230.
Bring next digit (4) of the dividend behind the 230 and repeat the process: 2304 / 449

Step 5:
When dividing 2304 by 449, we get 5 with a remainder of 59.
Record the quotient 5 as the next digit in the result. 
Result so far: 175.0
Subtracting 2245 from 2304 leaves us with 59.
Append the next digit (8) from the dividend to 59 and continue with: 598 / 449

Moving on to step 6:
If we divide 598 by 449, we get 1 and a remainder of 149.
Put 1 as the next digit of the answer. 
Result so far: 1751.0
Subtract 449 from 598 to get 149.
Take the next digit (0) from the dividend and append it to 149, then repeat: 1490 / 449

Moving on to step 7:
449 can be fit into 1490 3 times, resulting in a remainder of 143.
Record the quotient 3 as the next digit in the result. 
Result so far: 17513.0
Deduct 1347 from 1490 and we're left with 143.
Include the next digit (0) from the dividend after 143, then repeat: 1430 / 449

Going ahead to step 8:
449 can be fit into 1430 3 times, resulting in a remainder of 83.
Record the quotient 3 as the next digit in the result. 
Result so far: 175133.0
The remainder is 83 after subtracting 1347 from 1430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 9:
449 goes into 830 1 times with a remainder of 381.
Write down 1 as next digit of the result. 
Result so far: 175133.1
Subtracting 449 from 830 leaves us with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Advancing to step 10:
3810 divided by 449 is 8 with a remainder of 218.
Put 8 as the next digit of the answer. 
Result so far: 175133.18
If we take 3592 away from 3810, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 11:
The number 449 fits into 2180 4 times, leaving a remainder of 384.
Put 4 as the next digit of the answer. 
Result so far: 175133.184
Subtracting 1796 from 2180 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 12:
The number 449 fits into 3840 8 times, leaving a remainder of 248.
The number 8 becomes the next digit in our result. 
Result so far: 175133.1848
Subtract 3592 from 3840 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 13:
If we divide 2480 by 449, we get 5 and a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 175133.18485
If we take 2245 away from 2480, we end up with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 14:
If we divide 2350 by 449, we get 5 and a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 175133.184855
The remainder is 105 after subtracting 2245 from 2350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The quotient of the division is 175133.184855, and the remainder is 1.05e-05.
