49353624 divided by 645 
We want to figure out the number of times 49353624 can be divided by 645.

Moving on to step 1:
When dividing 4 by 645, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 645

On to step 2:
645 can be fit into 49 0 times, resulting in a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Fetch the next digit (3) from the dividend, attach it to 49 and continue: 493 / 645

On to step 3:
493 divided by 645 is 0 with a remainder of 493.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 493 and we're left with 493.
Grab the next digit (5) from the dividend, add it to 493, then carry on: 4935 / 645

On to step 4:
When dividing 4935 by 645, we get 7 with a remainder of 420.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 4515 away from 4935, we end up with 420.
Include the next digit (3) from the dividend after 420, then repeat: 4203 / 645

Step 5:
The number 645 fits into 4203 6 times, leaving a remainder of 333.
Put 6 as the next digit of the answer. 
Result so far: 76.0
The remainder is 333 after subtracting 3870 from 4203.
Append the next digit (6) from the dividend to 333 and continue with: 3336 / 645

On to step 6:
645 goes into 3336 5 times with a remainder of 111.
Use 5 as the next digit of our solution. 
Result so far: 765.0
If we take 3225 away from 3336, we end up with 111.
Fetch the next digit (2) from the dividend, attach it to 111 and continue: 1112 / 645

Step 7:
1112 divided by 645 is 1 with a remainder of 467.
Put 1 as the next digit of the answer. 
Result so far: 7651.0
Subtract 645 from 1112 to get 467.
Bring next digit (4) of the dividend behind the 467 and repeat the process: 4674 / 645

On to step 8:
If we divide 4674 by 645, we get 7 and a remainder of 159.
Write down 7 as next digit of the result. 
Result so far: 76517.0
The remainder is 159 after subtracting 4515 from 4674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Advancing to step 9:
1590 divided by 645 is 2 with a remainder of 300.
Record the quotient 2 as the next digit in the result. 
Result so far: 76517.2
The remainder is 300 after subtracting 1290 from 1590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 10:
The number 645 fits into 3000 4 times, leaving a remainder of 420.
The number 4 becomes the next digit in our result. 
Result so far: 76517.24
Subtract 2580 from 3000 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 11:
The number 645 fits into 4200 6 times, leaving a remainder of 330.
Put 6 as the next digit of the answer. 
Result so far: 76517.246
Subtract 3870 from 4200 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 12:
3300 divided by 645 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 76517.2465
If we subtract 3225 from 3300, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 13:
645 goes into 750 1 times with a remainder of 105.
Put 1 as the next digit of the answer. 
Result so far: 76517.24651
If we subtract 645 from 750, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 14:
1050 divided by 645 is 1 with a remainder of 405.
The number 1 becomes the next digit in our result. 
Result so far: 76517.246511
If we take 645 away from 1050, we end up with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Our division results in 76517.246511 with a remaining 4.05e-05.
