Let's divide 13053242 by 999
We're looking to find how many times 999 goes into 13053242.

Moving on to step 1:
999 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 999

Moving on to step 2:
999 goes into 13 0 times with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 999

Step 3:
999 goes into 130 0 times with a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 130 after subtracting 0 from 130.
Fetch the next digit (5) from the dividend, attach it to 130 and continue: 1305 / 999

Going ahead to step 4:
999 goes into 1305 1 times with a remainder of 306.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 999 from 1305 to get 306.
Append the next digit (3) from the dividend to 306 and continue with: 3063 / 999

Advancing to step 5:
3063 divided by 999 is 3 with a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 2997 from 3063 leaves us with 66.
Append the next digit (2) from the dividend to 66 and continue with: 662 / 999

Advancing to step 6:
662 divided by 999 is 0 with a remainder of 662.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
The remainder is 662 after subtracting 0 from 662.
Take the next digit (4) from the dividend and append it to 662, then repeat: 6624 / 999

Going ahead to step 7:
If we divide 6624 by 999, we get 6 and a remainder of 630.
The number 6 becomes the next digit in our result. 
Result so far: 1306.0
If we take 5994 away from 6624, we end up with 630.
Grab the next digit (2) from the dividend, add it to 630, then carry on: 6302 / 999

Moving on to step 8:
999 can be fit into 6302 6 times, resulting in a remainder of 308.
Record the quotient 6 as the next digit in the result. 
Result so far: 13066.0
The remainder is 308 after subtracting 5994 from 6302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 9:
999 can be fit into 3080 3 times, resulting in a remainder of 83.
Use 3 as the next digit of our solution. 
Result so far: 13066.3
Subtracting 2997 from 3080 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 10:
When dividing 830 by 999, we get 0 with a remainder of 830.
Record the quotient 0 as the next digit in the result. 
Result so far: 13066.3
Subtract 0 from 830 to get 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

On to step 11:
When dividing 8300 by 999, we get 8 with a remainder of 308.
Use 8 as the next digit of our solution. 
Result so far: 13066.308
If we take 7992 away from 8300, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 12:
When dividing 3080 by 999, we get 3 with a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 13066.3083
Subtract 2997 from 3080 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 13:
If we divide 830 by 999, we get 0 and a remainder of 830.
Put 0 as the next digit of the answer. 
Result so far: 13066.3083
Deduct 0 from 830 and we're left with 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Advancing to step 14:
999 goes into 8300 8 times with a remainder of 308.
The next digit of our result is 8. 
Result so far: 13066.308308
Deduct 7992 from 8300 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 15:
The number 999 fits into 3080 3 times, leaving a remainder of 83.
Use 3 as the next digit of our solution. 
Result so far: 13066.3083083
If we take 2997 away from 3080, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 16:
The number 999 fits into 830 0 times, leaving a remainder of 830.
The next digit of our result is 0. 
Result so far: 13066.3083083
Subtract 0 from 830 to get 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

The final outcome is 13066.3083083, with a leftover of 8.3e-07.
