991233 ÷ 53 
Our goal is to divide 991233 by 53.

Let's proceed to step 1:
If we divide 9 by 53, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 53

Going ahead to step 2:
The number 53 fits into 99 1 times, leaving a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 53 from 99 to get 46.
Bring next digit (1) of the dividend behind the 46 and repeat the process: 461 / 53

On to step 3:
53 goes into 461 8 times with a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtract 424 from 461 to get 37.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 53

Advancing to step 4:
If we divide 372 by 53, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 187.0
If we take 371 away from 372, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 53

Step 5:
13 divided by 53 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 1870.0
Deduct 0 from 13 and we're left with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 53

Moving on to step 6:
The number 53 fits into 133 2 times, leaving a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 18702.0
Subtracting 106 from 133 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
When dividing 270 by 53, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 18702.5
Subtract 265 from 270 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
50 divided by 53 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 18702.5
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
When dividing 500 by 53, we get 9 with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 18702.509
If we subtract 477 from 500, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 10:
53 goes into 230 4 times with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 18702.5094
Subtract 212 from 230 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 11:
53 goes into 180 3 times with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 18702.50943
Deduct 159 from 180 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 12:
The number 53 fits into 210 3 times, leaving a remainder of 51.
The next digit of our result is 3. 
Result so far: 18702.509433
Subtracting 159 from 210 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

After the division, we end up with 18702.509433 and a remainder of 5.1e-06.
