We're dividing 20249434 by 8 
Our goal is to divide 20249434 by 8.

On to step 1:
The number 8 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 8

Advancing to step 2:
The number 8 fits into 20 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 16 from 20, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 8

Going ahead to step 3:
8 can be fit into 42 5 times, resulting in a remainder of 2.
The next digit of our result is 5. 
Result so far: 25.0
The remainder is 2 after subtracting 40 from 42.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 8

Moving on to step 4:
When dividing 24 by 8, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 253.0
If we take 24 away from 24, we end up with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 8

Advancing to step 5:
8 can be fit into 9 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 2531.0
Subtract 8 from 9 to get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 8

Going ahead to step 6:
14 divided by 8 is 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 25311.0
Subtracting 8 from 14 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 8

Advancing to step 7:
The number 8 fits into 63 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 253117.0
The remainder is 7 after subtracting 56 from 63.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 8

Going ahead to step 8:
8 goes into 74 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 2531179.0
The remainder is 2 after subtracting 72 from 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
When dividing 20 by 8, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 2531179.2
The remainder is 4 after subtracting 16 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
If we divide 40 by 8, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2531179.25
Subtracting 40 from 40 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
If we divide 0 by 8, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2531179.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
When dividing 0 by 8, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2531179.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 2531179.25, and the remainder is 0.0.
