We look at the division of 316986 by 84 
We want to figure out the number of times 316986 can be divided by 84.

On to step 1:
When dividing 3 by 84, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 84

Let's proceed to step 2:
31 divided by 84 is 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 84

Advancing to step 3:
84 goes into 316 3 times with a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 252 from 316 to get 64.
Bring next digit (9) of the dividend behind the 64 and repeat the process: 649 / 84

On to step 4:
The number 84 fits into 649 7 times, leaving a remainder of 61.
Use 7 as the next digit of our solution. 
Result so far: 37.0
The remainder is 61 after subtracting 588 from 649.
Grab the next digit (8) from the dividend, add it to 61, then carry on: 618 / 84

Step 5:
84 can be fit into 618 7 times, resulting in a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 377.0
Deduct 588 from 618 and we're left with 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 84

Going ahead to step 6:
84 goes into 306 3 times with a remainder of 54.
Write down 3 as next digit of the result. 
Result so far: 3773.0
If we subtract 252 from 306, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 7:
540 divided by 84 is 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 3773.6
Subtract 504 from 540 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
If we divide 360 by 84, we get 4 and a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 3773.64
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
84 can be fit into 240 2 times, resulting in a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 3773.642
Subtracting 168 from 240 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 10:
720 divided by 84 is 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 3773.6428
Subtracting 672 from 720 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
When dividing 480 by 84, we get 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 3773.64285
Subtracting 420 from 480 leaves us 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.

Step 12:
84 goes into 600 7 times with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 3773.642857
If we subtract 588 from 600, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
84 can be fit into 120 1 times, resulting in a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 3773.6428571
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
360 divided by 84 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 3773.64285714
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 3773.64285714 and a remainder of 2.4e-08.
