81187720 divided by 685 
We want to divide 81187720 by 685.

Advancing to step 1:
8 divided by 685 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 685

On to step 2:
The number 685 fits into 81 0 times, leaving a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Grab the next digit (1) from the dividend, add it to 81, then carry on: 811 / 685

Going ahead to step 3:
685 goes into 811 1 times with a remainder of 126.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 685 away from 811, we end up with 126.
Take the next digit (8) from the dividend and append it to 126, then repeat: 1268 / 685

On to step 4:
685 can be fit into 1268 1 times, resulting in a remainder of 583.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 685 from 1268 leaves us with 583.
Take the next digit (7) from the dividend and append it to 583, then repeat: 5837 / 685

Going ahead to step 5:
The number 685 fits into 5837 8 times, leaving a remainder of 357.
Write down 8 as next digit of the result. 
Result so far: 118.0
The remainder is 357 after subtracting 5480 from 5837.
Bring next digit (7) of the dividend behind the 357 and repeat the process: 3577 / 685

Advancing to step 6:
3577 divided by 685 is 5 with a remainder of 152.
The next digit of our result is 5. 
Result so far: 1185.0
Deduct 3425 from 3577 and we're left with 152.
Take the next digit (2) from the dividend and append it to 152, then repeat: 1522 / 685

Step 7:
685 can be fit into 1522 2 times, resulting in a remainder of 152.
The next digit of our result is 2. 
Result so far: 11852.0
If we subtract 1370 from 1522, we get 152.
Fetch the next digit (0) from the dividend, attach it to 152 and continue: 1520 / 685

Moving on to step 8:
The number 685 fits into 1520 2 times, leaving a remainder of 150.
The number 2 becomes the next digit in our result. 
Result so far: 118522.0
Subtract 1370 from 1520 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 9:
If we divide 1500 by 685, we get 2 and a remainder of 130.
The number 2 becomes the next digit in our result. 
Result so far: 118522.2
Subtracting 1370 from 1500 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 10:
When dividing 1300 by 685, we get 1 with a remainder of 615.
Put 1 as the next digit of the answer. 
Result so far: 118522.21
Subtracting 685 from 1300 leaves us with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Moving on to step 11:
6150 divided by 685 is 8 with a remainder of 670.
The number 8 becomes the next digit in our result. 
Result so far: 118522.218
Deduct 5480 from 6150 and we're left with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

On to step 12:
685 can be fit into 6700 9 times, resulting in a remainder of 535.
Use 9 as the next digit of our solution. 
Result so far: 118522.2189
Deduct 6165 from 6700 and we're left with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Going ahead to step 13:
685 can be fit into 5350 7 times, resulting in a remainder of 555.
The number 7 becomes the next digit in our result. 
Result so far: 118522.21897
Deduct 4795 from 5350 and we're left with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Let's proceed to step 14:
When dividing 5550 by 685, we get 8 with a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 118522.218978
The remainder is 70 after subtracting 5480 from 5550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 15:
If we divide 700 by 685, we get 1 and a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 118522.2189781
Deduct 685 from 700 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 16:
150 divided by 685 is 0 with a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 118522.2189781
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

In conclusion, the division gives 118522.2189781 with a balance of 1.5e-07.
