We're dividing 128938 by 84 
We're looking to find how many times 84 goes into 128938.

Step 1:
If we divide 1 by 84, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 84

Going ahead to step 2:
12 divided by 84 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 84

Going ahead to step 3:
128 divided by 84 is 1 with 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.
Bring next digit (9) of the dividend behind the 44 and repeat the process: 449 / 84

On to step 4:
When dividing 449 by 84, we get 5 with a remainder of 29.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 420 from 449 to get 29.
Include the next digit (3) from the dividend after 29, then repeat: 293 / 84

Advancing to step 5:
When dividing 293 by 84, we get 3 with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
Deduct 252 from 293 and we're left with 41.
Include the next digit (8) from the dividend after 41, then repeat: 418 / 84

On to step 6:
If we divide 418 by 84, we get 4 and a remainder of 82.
Write down 4 as next digit of the result. 
Result so far: 1534.0
Deduct 336 from 418 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 7:
84 can be fit into 820 9 times, resulting in a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 1534.9
Subtract 756 from 820 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 8:
84 goes into 640 7 times with a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 1534.97
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.

On to step 9:
When dividing 520 by 84, we get 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 1534.976
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 10:
160 divided by 84 is 1 with a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 1534.9761
The remainder is 76 after subtracting 84 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
When dividing 760 by 84, we get 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 1534.97619
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.

Going ahead to step 12:
When dividing 40 by 84, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 1534.97619
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
The number 84 fits into 400 4 times, leaving a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 1534.9761904
Deduct 336 from 400 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 14:
The number 84 fits into 640 7 times, leaving a remainder of 52.
The next digit of our result is 7. 
Result so far: 1534.97619047
Deduct 588 from 640 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 1534.97619047, and the remainder is 5.2e-08.
