77955459 divided by 389 
Our goal is to divide 77955459 by 389.

Moving on to step 1:
If we divide 7 by 389, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 389

Going ahead to step 2:
When dividing 77 by 389, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Fetch the next digit (9) from the dividend, attach it to 77 and continue: 779 / 389

Let's proceed to step 3:
The number 389 fits into 779 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 778 from 779, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 389

On to step 4:
When dividing 15 by 389, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 389

Let's proceed to step 5:
389 can be fit into 155 0 times, resulting in a remainder of 155.
Write down 0 as next digit of the result. 
Result so far: 200.0
The remainder is 155 after subtracting 0 from 155.
Append the next digit (4) from the dividend to 155 and continue with: 1554 / 389

Let's proceed to step 6:
1554 divided by 389 is 3 with a remainder of 387.
Use 3 as the next digit of our solution. 
Result so far: 2003.0
The remainder is 387 after subtracting 1167 from 1554.
Include the next digit (5) from the dividend after 387, then repeat: 3875 / 389

Let's proceed to step 7:
389 goes into 3875 9 times with a remainder of 374.
Put 9 as the next digit of the answer. 
Result so far: 20039.0
If we take 3501 away from 3875, we end up with 374.
Grab the next digit (9) from the dividend, add it to 374, then carry on: 3749 / 389

Let's proceed to step 8:
When dividing 3749 by 389, we get 9 with a remainder of 248.
The next digit of our result is 9. 
Result so far: 200399.0
If we take 3501 away from 3749, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 9:
When dividing 2480 by 389, we get 6 with a remainder of 146.
The next digit of our result is 6. 
Result so far: 200399.6
The remainder is 146 after subtracting 2334 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 10:
The number 389 fits into 1460 3 times, leaving a remainder of 293.
Write down 3 as next digit of the result. 
Result so far: 200399.63
If we subtract 1167 from 1460, we get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

On to step 11:
When dividing 2930 by 389, we get 7 with a remainder of 207.
Use 7 as the next digit of our solution. 
Result so far: 200399.637
If we subtract 2723 from 2930, we get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Let's proceed to step 12:
2070 divided by 389 is 5 with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 200399.6375
If we take 1945 away from 2070, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 13:
1250 divided by 389 is 3 with a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 200399.63753
The remainder is 83 after subtracting 1167 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 14:
830 divided by 389 is 2 with a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 200399.637532
Subtracting 778 from 830 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 15:
520 divided by 389 is 1 with a remainder of 131.
Use 1 as the next digit of our solution. 
Result so far: 200399.6375321
The remainder is 131 after subtracting 389 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

On to step 16:
389 can be fit into 1310 3 times, resulting in a remainder of 143.
Record the quotient 3 as the next digit in the result. 
Result so far: 200399.63753213
If we take 1167 away from 1310, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

In conclusion, the division gives 200399.63753213 with a balance of 1.43e-07.
