Let's divide 48610619 by 645
Let's see how many times 645 fits into 48610619.

On to step 1:
If we divide 4 by 645, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 645

Going ahead to step 2:
645 can be fit into 48 0 times, resulting in a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Fetch the next digit (6) from the dividend, attach it to 48 and continue: 486 / 645

Step 3:
If we divide 486 by 645, we get 0 and a remainder of 486.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 486, we end up with 486.
Bring next digit (1) of the dividend behind the 486 and repeat the process: 4861 / 645

On to step 4:
4861 divided by 645 is 7 with a remainder of 346.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 4515 from 4861 to get 346.
Append the next digit (0) from the dividend to 346 and continue with: 3460 / 645

On to step 5:
When dividing 3460 by 645, we get 5 with a remainder of 235.
The next digit of our result is 5. 
Result so far: 75.0
Subtracting 3225 from 3460 leaves us with 235.
Take the next digit (6) from the dividend and append it to 235, then repeat: 2356 / 645

On to step 6:
645 goes into 2356 3 times with a remainder of 421.
Record the quotient 3 as the next digit in the result. 
Result so far: 753.0
If we subtract 1935 from 2356, we get 421.
Bring next digit (1) of the dividend behind the 421 and repeat the process: 4211 / 645

Let's proceed to step 7:
645 goes into 4211 6 times with a remainder of 341.
The number 6 becomes the next digit in our result. 
Result so far: 7536.0
Deduct 3870 from 4211 and we're left with 341.
Fetch the next digit (9) from the dividend, attach it to 341 and continue: 3419 / 645

Let's proceed to step 8:
If we divide 3419 by 645, we get 5 and a remainder of 194.
Put 5 as the next digit of the answer. 
Result so far: 75365.0
Subtracting 3225 from 3419 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

On to step 9:
If we divide 1940 by 645, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 75365.3
The remainder is 5 after subtracting 1935 from 1940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
645 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 75365.3
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
645 can be fit into 500 0 times, resulting in a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 75365.3
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The quotient of the division is 75365.3, and the remainder is 0.05.
