We look at the division of 125992 by 84 
Let's see how many times 84 fits into 125992.

Step 1:
84 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 84

Going ahead to step 2:
84 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 84

Moving on to step 3:
When dividing 125 by 84, we get 1 with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 41 after subtracting 84 from 125.
Fetch the next digit (9) from the dividend, attach it to 41 and continue: 419 / 84

Moving on to step 4:
When dividing 419 by 84, we get 4 with a remainder of 83.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 83 after subtracting 336 from 419.
Fetch the next digit (9) from the dividend, attach it to 83 and continue: 839 / 84

Step 5:
When dividing 839 by 84, we get 9 with a remainder of 83.
The next digit of our result is 9. 
Result so far: 149.0
Subtracting 756 from 839 leaves us with 83.
Grab the next digit (2) from the dividend, add it to 83, then carry on: 832 / 84

Advancing to step 6:
When dividing 832 by 84, we get 9 with a remainder of 76.
Record the quotient 9 as the next digit in the result. 
Result so far: 1499.0
If we subtract 756 from 832, 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.

Moving on to step 7:
If we divide 760 by 84, we get 9 and a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 1499.9
The remainder is 4 after subtracting 756 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
40 divided by 84 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 1499.9
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
If we divide 400 by 84, we get 4 and a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 1499.904
The remainder is 64 after subtracting 336 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 10:
If we divide 640 by 84, we get 7 and a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 1499.9047
Subtract 588 from 640 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
84 can be fit into 520 6 times, resulting in a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 1499.90476
Subtracting 504 from 520 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
84 goes into 160 1 times with a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 1499.904761
If we take 84 away from 160, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 13:
When dividing 760 by 84, we get 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 1499.9047619
Subtract 756 from 760 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
The number 84 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1499.9047619
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 1499.9047619 with a remainder of 4e-08.
