128960 divided by 84 
Let's see how many times 84 fits into 128960.

On to step 1:
When dividing 1 by 84, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 84

Advancing to step 2:
84 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 84

On to step 3:
The number 84 fits into 128 1 times, leaving a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 84 away from 128, we end up with 44.
Include the next digit (9) from the dividend after 44, then repeat: 449 / 84

Advancing to step 4:
84 can be fit into 449 5 times, resulting in a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 420 from 449, we get 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 84

Advancing to step 5:
84 can be fit into 296 3 times, resulting in a remainder of 44.
The next digit of our result is 3. 
Result so far: 153.0
Subtracting 252 from 296 leaves us with 44.
Include the next digit (0) from the dividend after 44, then repeat: 440 / 84

Let's proceed to step 6:
When dividing 440 by 84, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 1535.0
Subtract 420 from 440 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
84 can be fit into 200 2 times, resulting in a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 1535.2
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 8:
84 goes into 320 3 times with a remainder of 68.
The next digit of our result is 3. 
Result so far: 1535.23
If we subtract 252 from 320, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 9:
84 can be fit into 680 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 1535.238
If we subtract 672 from 680, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
When dividing 80 by 84, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 1535.238
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
The number 84 fits into 800 9 times, leaving a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 1535.23809
Deduct 756 from 800 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 12:
84 can be fit into 440 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 1535.238095
Subtract 420 from 440 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
When dividing 200 by 84, we get 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 1535.2380952
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
The number 84 fits into 320 3 times, leaving a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 1535.23809523
Deduct 252 from 320 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 1535.23809523, with a leftover of 6.8e-08.
