Let's divide 77685254 by 305
We want to figure out the number of times 77685254 can be divided by 305.

Advancing to step 1:
When dividing 7 by 305, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 305

Going ahead to step 2:
If we divide 77 by 305, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Fetch the next digit (6) from the dividend, attach it to 77 and continue: 776 / 305

Advancing to step 3:
The number 305 fits into 776 2 times, leaving a remainder of 166.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 610 from 776 and we're left with 166.
Append the next digit (8) from the dividend to 166 and continue with: 1668 / 305

On to step 4:
305 can be fit into 1668 5 times, resulting in a remainder of 143.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 1525 away from 1668, we end up with 143.
Include the next digit (5) from the dividend after 143, then repeat: 1435 / 305

Advancing to step 5:
When dividing 1435 by 305, we get 4 with a remainder of 215.
The number 4 becomes the next digit in our result. 
Result so far: 254.0
Subtract 1220 from 1435 to get 215.
Include the next digit (2) from the dividend after 215, then repeat: 2152 / 305

Let's proceed to step 6:
When dividing 2152 by 305, we get 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 2547.0
Subtract 2135 from 2152 to get 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 305

Going ahead to step 7:
When dividing 175 by 305, we get 0 with a remainder of 175.
Record the quotient 0 as the next digit in the result. 
Result so far: 25470.0
Subtract 0 from 175 to get 175.
Include the next digit (4) from the dividend after 175, then repeat: 1754 / 305

On to step 8:
If we divide 1754 by 305, we get 5 and a remainder of 229.
Put 5 as the next digit of the answer. 
Result so far: 254705.0
Deduct 1525 from 1754 and we're left with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Going ahead to step 9:
If we divide 2290 by 305, we get 7 and a remainder of 155.
Record the quotient 7 as the next digit in the result. 
Result so far: 254705.7
Subtracting 2135 from 2290 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 10:
1550 divided by 305 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 254705.75
If we subtract 1525 from 1550, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
If we divide 250 by 305, we get 0 and a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 254705.75
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 12:
The number 305 fits into 2500 8 times, leaving a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 254705.7508
If we take 2440 away from 2500, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 13:
600 divided by 305 is 1 with a remainder of 295.
Write down 1 as next digit of the result. 
Result so far: 254705.75081
Subtract 305 from 600 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 14:
When dividing 2950 by 305, we get 9 with a remainder of 205.
Record the quotient 9 as the next digit in the result. 
Result so far: 254705.750819
If we take 2745 away from 2950, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 15:
The number 305 fits into 2050 6 times, leaving a remainder of 220.
Use 6 as the next digit of our solution. 
Result so far: 254705.7508196
Subtracting 1830 from 2050 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 16:
If we divide 2200 by 305, we get 7 and a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 254705.75081967
Subtracting 2135 from 2200 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

In conclusion, the division gives 254705.75081967 with a balance of 6.5e-08.
