We divide 77860145 by 680
We want to figure out the number of times 77860145 can be divided by 680.

Step 1:
680 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
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 / 680

On to step 2:
680 can be fit into 77 0 times, resulting in a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Take the next digit (8) from the dividend and append it to 77, then repeat: 778 / 680

On to step 3:
When dividing 778 by 680, we get 1 with a remainder of 98.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 98 after subtracting 680 from 778.
Bring next digit (6) of the dividend behind the 98 and repeat the process: 986 / 680

Moving on to step 4:
The number 680 fits into 986 1 times, leaving a remainder of 306.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 680 from 986 and we're left with 306.
Grab the next digit (0) from the dividend, add it to 306, then carry on: 3060 / 680

On to step 5:
The number 680 fits into 3060 4 times, leaving a remainder of 340.
The next digit of our result is 4. 
Result so far: 114.0
If we take 2720 away from 3060, we end up with 340.
Append the next digit (1) from the dividend to 340 and continue with: 3401 / 680

Step 6:
If we divide 3401 by 680, we get 5 and a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 1145.0
Deduct 3400 from 3401 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 680

On to step 7:
When dividing 14 by 680, we get 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 11450.0
Subtracting 0 from 14 leaves us with 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 680

Going ahead to step 8:
145 divided by 680 is 0 with a remainder of 145.
The number 0 becomes the next digit in our result. 
Result so far: 114500.0
Deduct 0 from 145 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 9:
The number 680 fits into 1450 2 times, leaving a remainder of 90.
The number 2 becomes the next digit in our result. 
Result so far: 114500.2
Subtract 1360 from 1450 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 10:
The number 680 fits into 900 1 times, leaving a remainder of 220.
The next digit of our result is 1. 
Result so far: 114500.21
If we take 680 away from 900, we end up 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.

Step 11:
680 can be fit into 2200 3 times, resulting in a remainder of 160.
The number 3 becomes the next digit in our result. 
Result so far: 114500.213
If we subtract 2040 from 2200, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 12:
1600 divided by 680 is 2 with a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 114500.2132
Subtract 1360 from 1600 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 13:
When dividing 2400 by 680, we get 3 with a remainder of 360.
Use 3 as the next digit of our solution. 
Result so far: 114500.21323
Subtract 2040 from 2400 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 14:
680 goes into 3600 5 times with a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 114500.213235
Subtract 3400 from 3600 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 15:
680 goes into 2000 2 times with a remainder of 640.
The next digit of our result is 2. 
Result so far: 114500.2132352
The remainder is 640 after subtracting 1360 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 16:
680 goes into 6400 9 times with a remainder of 280.
The number 9 becomes the next digit in our result. 
Result so far: 114500.21323529
If we subtract 6120 from 6400, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

After the division, we end up with 114500.21323529 and a remainder of 2.8e-07.
