We're dividing 121889 by 53 
Our goal is to divide 121889 by 53.

Going ahead to step 1:
When dividing 1 by 53, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 53

Moving on to step 2:
53 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 53

Step 3:
121 divided by 53 is 2 with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 106 from 121 to get 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 53

Advancing to step 4:
When dividing 158 by 53, we get 2 with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we take 106 away from 158, we end up with 52.
Include the next digit (8) from the dividend after 52, then repeat: 528 / 53

Going ahead to step 5:
The number 53 fits into 528 9 times, leaving a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 229.0
Subtracting 477 from 528 leaves us with 51.
Fetch the next digit (9) from the dividend, attach it to 51 and continue: 519 / 53

Let's proceed to step 6:
The number 53 fits into 519 9 times, leaving a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 2299.0
Subtracting 477 from 519 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
If we divide 420 by 53, we get 7 and a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 2299.7
Subtract 371 from 420 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 8:
53 goes into 490 9 times with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 2299.79
Deduct 477 from 490 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
53 can be fit into 130 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 2299.792
Subtracting 106 from 130 leaves us 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.

Step 10:
When dividing 240 by 53, we get 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 2299.7924
Subtract 212 from 240 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
The number 53 fits into 280 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 2299.79245
If we subtract 265 from 280, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
The number 53 fits into 150 2 times, leaving a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 2299.792452
Subtracting 106 from 150 leaves us 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 13:
53 goes into 440 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 2299.7924528
If we subtract 424 from 440, 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 14:
53 can be fit into 160 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 2299.79245283
Subtracting 159 from 160 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 2299.79245283 with a balance of 1e-09.
