We look at the division of 84106974 by 685 
We want to divide 84106974 by 685.

Step 1:
685 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 685

Moving on to step 2:
685 can be fit into 84 0 times, resulting in a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Append the next digit (1) from the dividend to 84 and continue with: 841 / 685

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

Going ahead to step 4:
The number 685 fits into 1560 2 times, leaving a remainder of 190.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1370 from 1560 to get 190.
Bring next digit (6) of the dividend behind the 190 and repeat the process: 1906 / 685

Step 5:
1906 divided by 685 is 2 with a remainder of 536.
Use 2 as the next digit of our solution. 
Result so far: 122.0
If we take 1370 away from 1906, we end up with 536.
Fetch the next digit (9) from the dividend, attach it to 536 and continue: 5369 / 685

Step 6:
The number 685 fits into 5369 7 times, leaving a remainder of 574.
The next digit of our result is 7. 
Result so far: 1227.0
If we subtract 4795 from 5369, we get 574.
Bring next digit (7) of the dividend behind the 574 and repeat the process: 5747 / 685

Advancing to step 7:
If we divide 5747 by 685, we get 8 and a remainder of 267.
Put 8 as the next digit of the answer. 
Result so far: 12278.0
Subtracting 5480 from 5747 leaves us with 267.
Include the next digit (4) from the dividend after 267, then repeat: 2674 / 685

Step 8:
685 can be fit into 2674 3 times, resulting in a remainder of 619.
The number 3 becomes the next digit in our result. 
Result so far: 122783.0
The remainder is 619 after subtracting 2055 from 2674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Advancing to step 9:
685 can be fit into 6190 9 times, resulting in a remainder of 25.
The next digit of our result is 9. 
Result so far: 122783.9
If we subtract 6165 from 6190, 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.

Advancing to step 10:
When dividing 250 by 685, we get 0 with a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 122783.9
Deduct 0 from 250 and we're left 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.

Going ahead to step 11:
685 goes into 2500 3 times with a remainder of 445.
Put 3 as the next digit of the answer. 
Result so far: 122783.903
If we subtract 2055 from 2500, we get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Let's proceed to step 12:
When dividing 4450 by 685, we get 6 with a remainder of 340.
Record the quotient 6 as the next digit in the result. 
Result so far: 122783.9036
If we take 4110 away from 4450, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 13:
When dividing 3400 by 685, we get 4 with a remainder of 660.
Use 4 as the next digit of our solution. 
Result so far: 122783.90364
If we take 2740 away from 3400, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Step 14:
685 goes into 6600 9 times with a remainder of 435.
The number 9 becomes the next digit in our result. 
Result so far: 122783.903649
If we subtract 6165 from 6600, we get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Moving on to step 15:
When dividing 4350 by 685, we get 6 with a remainder of 240.
The number 6 becomes the next digit in our result. 
Result so far: 122783.9036496
Deduct 4110 from 4350 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 16:
When dividing 2400 by 685, we get 3 with a remainder of 345.
Use 3 as the next digit of our solution. 
Result so far: 122783.90364963
If we subtract 2055 from 2400, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

The final result is 122783.90364963 with a remainder of 3.45e-07.
