49702888 ÷ 645 
We want to divide 49702888 by 645.

On to step 1:
645 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 645

Moving on to step 2:
When dividing 49 by 645, we get 0 with a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Include the next digit (7) from the dividend after 49, then repeat: 497 / 645

On to step 3:
645 can be fit into 497 0 times, resulting in a remainder of 497.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 497 to get 497.
Bring next digit (0) of the dividend behind the 497 and repeat the process: 4970 / 645

Step 4:
645 can be fit into 4970 7 times, resulting in a remainder of 455.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 4515 away from 4970, we end up with 455.
Take the next digit (2) from the dividend and append it to 455, then repeat: 4552 / 645

Moving on to step 5:
645 goes into 4552 7 times with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Subtract 4515 from 4552 to get 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 645

Advancing to step 6:
The number 645 fits into 378 0 times, leaving a remainder of 378.
Put 0 as the next digit of the answer. 
Result so far: 770.0
The remainder is 378 after subtracting 0 from 378.
Take the next digit (8) from the dividend and append it to 378, then repeat: 3788 / 645

Going ahead to step 7:
If we divide 3788 by 645, we get 5 and a remainder of 563.
Write down 5 as next digit of the result. 
Result so far: 7705.0
If we subtract 3225 from 3788, we get 563.
Include the next digit (8) from the dividend after 563, then repeat: 5638 / 645

On to step 8:
When dividing 5638 by 645, we get 8 with a remainder of 478.
The number 8 becomes the next digit in our result. 
Result so far: 77058.0
Subtracting 5160 from 5638 leaves us with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Let's proceed to step 9:
The number 645 fits into 4780 7 times, leaving a remainder of 265.
The number 7 becomes the next digit in our result. 
Result so far: 77058.7
If we subtract 4515 from 4780, we get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 10:
645 goes into 2650 4 times with a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 77058.74
Subtract 2580 from 2650 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 11:
645 can be fit into 700 1 times, resulting in a remainder of 55.
Record the quotient 1 as the next digit in the result. 
Result so far: 77058.741
The remainder is 55 after subtracting 645 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 12:
550 divided by 645 is 0 with a remainder of 550.
Put 0 as the next digit of the answer. 
Result so far: 77058.741
Subtract 0 from 550 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 13:
The number 645 fits into 5500 8 times, leaving a remainder of 340.
Write down 8 as next digit of the result. 
Result so far: 77058.74108
Subtracting 5160 from 5500 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 14:
3400 divided by 645 is 5 with a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 77058.741085
Subtracting 3225 from 3400 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 15:
645 can be fit into 1750 2 times, resulting in a remainder of 460.
The next digit of our result is 2. 
Result so far: 77058.7410852
The remainder is 460 after subtracting 1290 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 16:
If we divide 4600 by 645, we get 7 and a remainder of 85.
Put 7 as the next digit of the answer. 
Result so far: 77058.74108527
Deduct 4515 from 4600 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The quotient of the division is 77058.74108527, and the remainder is 8.5e-08.
