We're dividing 77661924 by 389 
We want to divide 77661924 by 389.

Going ahead to step 1:
The number 389 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 389

Let's proceed to step 2:
389 can be fit into 77 0 times, resulting in a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Grab the next digit (6) from the dividend, add it to 77, then carry on: 776 / 389

Advancing to step 3:
When dividing 776 by 389, we get 1 with a remainder of 387.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 389 from 776 to get 387.
Grab the next digit (6) from the dividend, add it to 387, then carry on: 3876 / 389

Advancing to step 4:
The number 389 fits into 3876 9 times, leaving a remainder of 375.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 375 after subtracting 3501 from 3876.
Grab the next digit (1) from the dividend, add it to 375, then carry on: 3751 / 389

On to step 5:
When dividing 3751 by 389, we get 9 with a remainder of 250.
Put 9 as the next digit of the answer. 
Result so far: 199.0
Deduct 3501 from 3751 and we're left with 250.
Bring next digit (9) of the dividend behind the 250 and repeat the process: 2509 / 389

Going ahead to step 6:
If we divide 2509 by 389, we get 6 and a remainder of 175.
Record the quotient 6 as the next digit in the result. 
Result so far: 1996.0
Subtracting 2334 from 2509 leaves us with 175.
Bring next digit (2) of the dividend behind the 175 and repeat the process: 1752 / 389

Step 7:
389 goes into 1752 4 times with a remainder of 196.
The number 4 becomes the next digit in our result. 
Result so far: 19964.0
Subtract 1556 from 1752 to get 196.
Take the next digit (4) from the dividend and append it to 196, then repeat: 1964 / 389

Moving on to step 8:
389 goes into 1964 5 times with a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 199645.0
Subtracting 1945 from 1964 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 9:
If we divide 190 by 389, we get 0 and a remainder of 190.
Use 0 as the next digit of our solution. 
Result so far: 199645.0
The remainder is 190 after subtracting 0 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 10:
The number 389 fits into 1900 4 times, leaving a remainder of 344.
Use 4 as the next digit of our solution. 
Result so far: 199645.04
The remainder is 344 after subtracting 1556 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 11:
389 goes into 3440 8 times with a remainder of 328.
Record the quotient 8 as the next digit in the result. 
Result so far: 199645.048
Deduct 3112 from 3440 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 12:
When dividing 3280 by 389, we get 8 with a remainder of 168.
Write down 8 as next digit of the result. 
Result so far: 199645.0488
Subtract 3112 from 3280 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final outcome is 199645.0488, with a leftover of 0.00168.
