We look at the division of 612991 by 84 
We want to divide 612991 by 84.

Let's proceed to step 1:
84 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 84

On to step 2:
If we divide 61 by 84, we get 0 and a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Append the next digit (2) from the dividend to 61 and continue with: 612 / 84

Moving on to step 3:
The number 84 fits into 612 7 times, leaving a remainder of 24.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 588 from 612, we get 24.
Grab the next digit (9) from the dividend, add it to 24, then carry on: 249 / 84

Advancing to step 4:
84 can be fit into 249 2 times, resulting in a remainder of 81.
Put 2 as the next digit of the answer. 
Result so far: 72.0
If we take 168 away from 249, we end up with 81.
Take the next digit (9) from the dividend and append it to 81, then repeat: 819 / 84

Step 5:
The number 84 fits into 819 9 times, leaving a remainder of 63.
The number 9 becomes the next digit in our result. 
Result so far: 729.0
If we take 756 away from 819, we end up with 63.
Include the next digit (1) from the dividend after 63, then repeat: 631 / 84

On to step 6:
84 can be fit into 631 7 times, resulting in a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 7297.0
Subtract 588 from 631 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
If we divide 430 by 84, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 7297.5
Subtract 420 from 430 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
100 divided by 84 is 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 7297.51
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
When dividing 160 by 84, we get 1 with a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 7297.511
If we subtract 84 from 160, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 7297.511, with a leftover of 0.0076.
