Let's divide 77381875 by 243
Let's see how many times 243 fits into 77381875.

Step 1:
When dividing 7 by 243, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 243

Step 2:
The number 243 fits into 77 0 times, leaving a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Fetch the next digit (3) from the dividend, attach it to 77 and continue: 773 / 243

Step 3:
When dividing 773 by 243, we get 3 with a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 729 from 773, we get 44.
Grab the next digit (8) from the dividend, add it to 44, then carry on: 448 / 243

Step 4:
The number 243 fits into 448 1 times, leaving a remainder of 205.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
The remainder is 205 after subtracting 243 from 448.
Fetch the next digit (1) from the dividend, attach it to 205 and continue: 2051 / 243

Let's proceed to step 5:
2051 divided by 243 is 8 with a remainder of 107.
Write down 8 as next digit of the result. 
Result so far: 318.0
If we subtract 1944 from 2051, we get 107.
Include the next digit (8) from the dividend after 107, then repeat: 1078 / 243

Advancing to step 6:
243 can be fit into 1078 4 times, resulting in a remainder of 106.
Record the quotient 4 as the next digit in the result. 
Result so far: 3184.0
Deduct 972 from 1078 and we're left with 106.
Take the next digit (7) from the dividend and append it to 106, then repeat: 1067 / 243

On to step 7:
The number 243 fits into 1067 4 times, leaving a remainder of 95.
Record the quotient 4 as the next digit in the result. 
Result so far: 31844.0
The remainder is 95 after subtracting 972 from 1067.
Grab the next digit (5) from the dividend, add it to 95, then carry on: 955 / 243

Going ahead to step 8:
The number 243 fits into 955 3 times, leaving a remainder of 226.
Put 3 as the next digit of the answer. 
Result so far: 318443.0
Subtracting 729 from 955 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 9:
243 can be fit into 2260 9 times, resulting in a remainder of 73.
Record the quotient 9 as the next digit in the result. 
Result so far: 318443.9
Subtract 2187 from 2260 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 10:
243 goes into 730 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 318443.93
Subtract 729 from 730 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
243 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 318443.93
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
243 goes into 100 0 times with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 318443.93
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 318443.93, and the remainder is 0.001.
