We're dividing 30453925 by 8 
Our goal is to divide 30453925 by 8.

On to step 1:
If we divide 3 by 8, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 8

Going ahead to step 2:
If we divide 30 by 8, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 24 away from 30, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 8

Step 3:
The number 8 fits into 64 8 times, leaving a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Deduct 64 from 64 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 8

Moving on to step 4:
5 divided by 8 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 380.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 8

On to step 5:
The number 8 fits into 53 6 times, leaving a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 3806.0
Deduct 48 from 53 and we're left with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 8

Let's proceed to step 6:
The number 8 fits into 59 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 38067.0
The remainder is 3 after subtracting 56 from 59.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 8

Step 7:
If we divide 32 by 8, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 380674.0
If we subtract 32 from 32, we get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 8

Moving on to step 8:
8 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 3806740.0
Deduct 0 from 5 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
50 divided by 8 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 3806740.6
Subtracting 48 from 50 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
20 divided by 8 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 3806740.62
Subtract 16 from 20 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
When dividing 40 by 8, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 3806740.625
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.

Advancing to step 12:
If we divide 0 by 8, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3806740.625
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.

Going ahead to step 13:
8 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3806740.625
Subtract 0 from 0 to 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.

Our division results in 3806740.625 with a remaining 0.0.
