We're dividing 12155621 by 488 
We want to divide 12155621 by 488.

Going ahead to step 1:
488 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 488

Let's proceed to step 2:
When dividing 12 by 488, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 488

Moving on to step 3:
488 can be fit into 121 0 times, resulting in a remainder of 121.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 121 and we're left with 121.
Grab the next digit (5) from the dividend, add it to 121, then carry on: 1215 / 488

Let's proceed to step 4:
488 goes into 1215 2 times with a remainder of 239.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 976 from 1215 leaves us with 239.
Fetch the next digit (5) from the dividend, attach it to 239 and continue: 2395 / 488

Advancing to step 5:
488 can be fit into 2395 4 times, resulting in a remainder of 443.
Write down 4 as next digit of the result. 
Result so far: 24.0
Deduct 1952 from 2395 and we're left with 443.
Append the next digit (6) from the dividend to 443 and continue with: 4436 / 488

Going ahead to step 6:
If we divide 4436 by 488, we get 9 and a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 249.0
If we subtract 4392 from 4436, we get 44.
Fetch the next digit (2) from the dividend, attach it to 44 and continue: 442 / 488

On to step 7:
The number 488 fits into 442 0 times, leaving a remainder of 442.
The number 0 becomes the next digit in our result. 
Result so far: 2490.0
The remainder is 442 after subtracting 0 from 442.
Include the next digit (1) from the dividend after 442, then repeat: 4421 / 488

Advancing to step 8:
When dividing 4421 by 488, we get 9 with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 24909.0
If we subtract 4392 from 4421, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 9:
488 goes into 290 0 times with a remainder of 290.
The number 0 becomes the next digit in our result. 
Result so far: 24909.0
Subtracting 0 from 290 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 10:
488 can be fit into 2900 5 times, resulting in a remainder of 460.
Record the quotient 5 as the next digit in the result. 
Result so far: 24909.05
Subtracting 2440 from 2900 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 11:
488 can be fit into 4600 9 times, resulting in a remainder of 208.
Use 9 as the next digit of our solution. 
Result so far: 24909.059
If we subtract 4392 from 4600, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 12:
If we divide 2080 by 488, we get 4 and a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 24909.0594
Deduct 1952 from 2080 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 13:
When dividing 1280 by 488, we get 2 with a remainder of 304.
The number 2 becomes the next digit in our result. 
Result so far: 24909.05942
Deduct 976 from 1280 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 14:
The number 488 fits into 3040 6 times, leaving a remainder of 112.
Record the quotient 6 as the next digit in the result. 
Result so far: 24909.059426
Subtract 2928 from 3040 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 15:
When dividing 1120 by 488, we get 2 with a remainder of 144.
Record the quotient 2 as the next digit in the result. 
Result so far: 24909.0594262
Subtract 976 from 1120 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 16:
If we divide 1440 by 488, we get 2 and a remainder of 464.
The next digit of our result is 2. 
Result so far: 24909.05942622
If we take 976 away from 1440, we end up with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

In conclusion, the division gives 24909.05942622 with a balance of 4.64e-07.
