Append the next digit (1) from the dividend to 84 and continue with: 841 / 685

On to step 3:
841 divided by 685 is 1 with a remainder of 156.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 685 from 841, we get 156.
Bring next digit (0) of the dividend behind the 156 and repeat the process: 1560 / 685

Moving on to step 4:
685 goes into 1560 2 times with a remainder of 190.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 1370 from 1560 and we're left with 190.
Append the next digit (1) from the dividend to 190 and continue with: 1901 / 685

Advancing to step 5:
685 can be fit into 1901 2 times, resulting in a remainder of 531.
Write down 2 as next digit of the result. 
Result so far: 122.0
If we subtract 1370 from 1901, we get 531.
Bring next digit (9) of the dividend behind the 531 and repeat the process: 5319 / 685

On to step 6:
The number 685 fits into 5319 7 times, leaving a remainder of 524.
Put 7 as the next digit of the answer. 
Result so far: 1227.0
The remainder is 524 after subtracting 4795 from 5319.
Append the next digit (1) from the dividend to 524 and continue with: 5241 / 685

Moving on to step 7:
685 can be fit into 5241 7 times, resulting in a remainder of 446.
The next digit of our result is 7. 
Result so far: 12277.0
Deduct 4795 from 5241 and we're left with 446.
Include the next digit (9) from the dividend after 446, then repeat: 4469 / 685

Step 8:
685 goes into 4469 6 times with a remainder of 359.
Put 6 as the next digit of the answer. 
Result so far: 122776.0
If we subtract 4110 from 4469, we get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Advancing to step 9:
685 can be fit into 3590 5 times, resulting in a remainder of 165.
Put 5 as the next digit of the answer. 
Result so far: 122776.5
Subtracting 3425 from 3590 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 10:
685 goes into 1650 2 times with a remainder of 280.
Put 2 as the next digit of the answer. 
Result so far: 122776.52
The remainder is 280 after subtracting 1370 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 11:
If we divide 2800 by 685, we get 4 and a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 122776.524
The remainder is 60 after subtracting 2740 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
When dividing 600 by 685, we get 0 with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 122776.524
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 13:
If we divide 6000 by 685, we get 8 and a remainder of 520.
The next digit of our result is 8. 
Result so far: 122776.52408
If we subtract 5480 from 6000, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 14:
When dividing 5200 by 685, we get 7 with a remainder of 405.
Write down 7 as next digit of the result. 
Result so far: 122776.524087
If we take 4795 away from 5200, we end up with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Advancing to step 15:
When dividing 4050 by 685, we get 5 with a remainder of 625.
Write down 5 as next digit of the result. 
Result so far: 122776.5240875
If we take 3425 away from 4050, we end up with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Going ahead to step 16:
The number 685 fits into 6250 9 times, leaving a remainder of 85.
Record the quotient 9 as the next digit in the result. 
Result so far: 122776.52408759
The remainder is 85 after subtracting 6165 from 6250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Our division results in 122776.52408759 with a remaining 8.5e-08.
