Let's divide 12720009 by 462
Our goal is to divide 12720009 by 462.

Going ahead to step 1:
462 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 462

Advancing to step 2:
If we divide 12 by 462, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 462

Let's proceed to step 3:
When dividing 127 by 462, we get 0 with a remainder of 127.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 127 leaves us with 127.
Include the next digit (2) from the dividend after 127, then repeat: 1272 / 462

Advancing to step 4:
When dividing 1272 by 462, we get 2 with a remainder of 348.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 924 from 1272, we get 348.
Grab the next digit (0) from the dividend, add it to 348, then carry on: 3480 / 462

On to step 5:
462 goes into 3480 7 times with a remainder of 246.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Subtract 3234 from 3480 to get 246.
Append the next digit (0) from the dividend to 246 and continue with: 2460 / 462

Let's proceed to step 6:
The number 462 fits into 2460 5 times, leaving a remainder of 150.
The next digit of our result is 5. 
Result so far: 275.0
Subtracting 2310 from 2460 leaves us with 150.
Append the next digit (0) from the dividend to 150 and continue with: 1500 / 462

Step 7:
When dividing 1500 by 462, we get 3 with a remainder of 114.
Use 3 as the next digit of our solution. 
Result so far: 2753.0
Deduct 1386 from 1500 and we're left with 114.
Grab the next digit (9) from the dividend, add it to 114, then carry on: 1149 / 462

Advancing to step 8:
462 can be fit into 1149 2 times, resulting in a remainder of 225.
Use 2 as the next digit of our solution. 
Result so far: 27532.0
If we subtract 924 from 1149, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 9:
If we divide 2250 by 462, we get 4 and a remainder of 402.
Write down 4 as next digit of the result. 
Result so far: 27532.4
Deduct 1848 from 2250 and we're left with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Advancing to step 10:
462 can be fit into 4020 8 times, resulting in a remainder of 324.
Write down 8 as next digit of the result. 
Result so far: 27532.48
Deduct 3696 from 4020 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Moving on to step 11:
462 can be fit into 3240 7 times, resulting in a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 27532.487
Subtract 3234 from 3240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
60 divided by 462 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 27532.487
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
If we divide 600 by 462, we get 1 and a remainder of 138.
The next digit of our result is 1. 
Result so far: 27532.48701
Deduct 462 from 600 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 14:
462 can be fit into 1380 2 times, resulting in a remainder of 456.
Write down 2 as next digit of the result. 
Result so far: 27532.487012
Deduct 924 from 1380 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Going ahead to step 15:
When dividing 4560 by 462, we get 9 with a remainder of 402.
Record the quotient 9 as the next digit in the result. 
Result so far: 27532.4870129
If we take 4158 away from 4560, we end up with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Moving on to step 16:
If we divide 4020 by 462, we get 8 and a remainder of 324.
Write down 8 as next digit of the result. 
Result so far: 27532.48701298
If we take 3696 away from 4020, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

In conclusion, the division gives 27532.48701298 with a balance of 3.24e-07.
