12842179 ÷ 225 
Our goal is to divide 12842179 by 225.

Going ahead to step 1:
1 divided by 225 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 225

Let's proceed to step 2:
12 divided by 225 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 225

On to step 3:
128 divided by 225 is 0 with a remainder of 128.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 128 to get 128.
Take the next digit (4) from the dividend and append it to 128, then repeat: 1284 / 225

Advancing to step 4:
If we divide 1284 by 225, we get 5 and a remainder of 159.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 159 after subtracting 1125 from 1284.
Append the next digit (2) from the dividend to 159 and continue with: 1592 / 225

On to step 5:
225 goes into 1592 7 times with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
The remainder is 17 after subtracting 1575 from 1592.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 225

Moving on to step 6:
If we divide 171 by 225, we get 0 and a remainder of 171.
Put 0 as the next digit of the answer. 
Result so far: 570.0
If we subtract 0 from 171, we get 171.
Grab the next digit (7) from the dividend, add it to 171, then carry on: 1717 / 225

Let's proceed to step 7:
225 can be fit into 1717 7 times, resulting in a remainder of 142.
Put 7 as the next digit of the answer. 
Result so far: 5707.0
Deduct 1575 from 1717 and we're left with 142.
Include the next digit (9) from the dividend after 142, then repeat: 1429 / 225

Step 8:
225 can be fit into 1429 6 times, resulting in a remainder of 79.
Write down 6 as next digit of the result. 
Result so far: 57076.0
If we subtract 1350 from 1429, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 9:
790 divided by 225 is 3 with a remainder of 115.
The next digit of our result is 3. 
Result so far: 57076.3
The remainder is 115 after subtracting 675 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 10:
225 goes into 1150 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 57076.35
Subtracting 1125 from 1150 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
225 goes into 250 1 times with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 57076.351
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 12:
225 goes into 250 1 times with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 57076.3511
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 57076.3511, and the remainder is 0.00025.
